Mater, Research, vol.8, page 3233 (1993), which is incorporated herein by reference. In 1976, Endo et al. (see Obelin, A. and Endo, M., J. of Crystal Growth, vol, 32 (1976), pp. 335-349, which is incorporated herein by reference) elucidated the mechanism It is seen that they originated from a metallic catalyst particle that, in the presence of a hydrocarbon-containing gas, is supersaturated with carbon.A cylindrical ordered graphitic core is extruded which immediately, According to Endo et al., it is covered with an external layer of graphite deposited pyrolically, these fibrils with an ionic pyrol coating have typically diameters greater than 0.1 μ, more typically between 0.2 and f.5 μ. Ert 1983, Tennent, in the North American patent no. No. 4,663,230, which is incorporated herein by reference, managed to grow cylindrical ordered graphite cores, not contaminated with pyrolytic carbon. Accordingly, Tennent's invention provided access to fibrils of smaller diameters, typically 35 to 700 angstroms (0.0035 to 0.070 μ) and to a graffiti surface "in the co-or grown" state, ordered. Fibrillar carbons of a perfect ñßnos structure but also without an outer layer of pyrolytic carbon also grew. The fibrils, fullerenes and nanofibers operated in this application are distinguished from commercially available continuous carbon fibers or reinforcing materials. In contrast to fibrils, which have desirably large but inevitably finite aspect ratios, continuous carbon fibers have aspect ratios (Length / Diameter) of at least 10,000 and frequently 1,000,000 or more. The diameter of the continuous fibers is also much greater than the diameter of the fibrils, always above 1.0 μ and typically between 5 and 7 μ. Continuous carbon fibers are made by pyrolysis of organic precursor fibers, usually rayon, pal iacri loni tri lo (PAN) and tar. Accordingly, they may include heteroatoms within their structure. The graphite nature of the continuous "as-processed" carbon fibers varies, but they can be subjected to a subsequent graphing step. Differences in the degree of graphitization, orientation and crystallinity of the graphite planes, if present, the potential presence of heteroatoms and even the absolute difference in substrate diameter make the experience with continuous fibers a limited predictor of the chemistry of the nanofibras .: Tennent, in the North American patent no. No. 4,663,230 discloses free carbon fibrils of a continuous thermal carbon coating and has numerous graphitic outer layers substantially parallel to the axis of the fibril. As such they can be characterized as having their axes c, the axes that are perpendicular to the tangents of the graphite curved layers, substantially perpendicular to their cylindrical axes. They generally have diameters not greater than 0.1 μ and proportions between the diameter length of at least 5. Desirably they are substantially free of a continuous thermal carbon coating, i.e., pyrolitically deposited carbon resulting from the thermal decomposition of the gas fed used to prepare them. Tennent et al., In U.S. Pat. No. 5,171,560, which is incorporated herein by reference, discloses carbon fibrils free from thermal coating and having graffiti layers substantially parallel to the axes of the fibrils such that the projection of said layers on said fibril shafts extends over a distance of at least two diameters of fibril. Typically, such fibrils are substantially cylindrical graphitic nanophones of a substantially constant diameter and comprise cylindrical graphite sheets whose axes c are substantially perpendicular to their cylindrical axis. They are substantially free of carbon deposited piratically, have a diameter of less than 0.1 μ, have a ratio of length to diameter greater than 5, These fibrils are of primary interest in the invention. Additional details regarding the formation of carbon fibril aggregates can be found in the presentation by Snyder et al., Nartea and icana patent application no. of series 149,573, filed on January 28, 1988, and the PCT application no. US89 00322, filed on January 28, 1989 ("carbon fibrils") WO 89/07163, and today et al., US patent application no. series -3-13,837, filed September 28, 1989, and PCT application number US90 / 05498, filed on September 27, 1990 ("Fibril Aggregates and Methods for Making Them") WO 91/05089, which is incorporated by reference in its entirety. they all assign to the same assignee as the present invention which are incorporated herein by reference. Moy et al., In USSN 07 / 887,307 filed May 22, 1992, which is incorporated herein by reference, discloses separate fibrils as aggregates having various macroscopic morphologies (as determined by scanning electron microscopy), wherein they are randomly entangled between them to form tangled fibril balls that resemble bird nests ("BN"); or with aggregates consisting of bundles of straight or slightly bent or twisted carbon fibrils having their tanc and the same relative orientation, and having the appearance of combed yarn ("CY") for example, the longitudinal axis of each fibril (in spite of individual folds or retrofits) extends in the same direction as the direction of the adjacent fibrils in the bundles; or, as aggregates consisting of straight to slightly bent or twisted fibrils that are tangled loosely together to form an "open network" ("ON") structure. In open network structures, the degree of fibril entanglement is greater than that observed in combed thread aggregates (where individual fibrils have substantially the same relative orientation) but less than the entanglement of bird nests. Read additions CY and ON are more easily dispersed than DN making them useful in composite manufacturing, where uniform properties are desired throughout the structure. When the projection of the graphite layers on the axis of the fibrils extends over a distance less than two diameters of fibril, the carbon planes of the graphitic nanofiber, in section, to the appearance of a fishbone. These are known as fishbone fibrils, Geu, in US Patent no. No. 4,855,091, which is incorporated herein by reference, provides a process for the preparation of fish-fiber fibrils. Try free of pyrolytic coating. These fibrils are also useful in the practice of the invention. Carbon nonotubes of a morphology similar to the catalytically grown fibrils described above grew in a carbon arc at elevated temperature (Iijima, Na ture 354 56 1991). It is now generally accepted (Weaver, Science 265 1994) that these nanofibers that grew in arc have the same morphology as the previous fibrils that grew catically from Tennent. The carbon nanofibers that grew in arc are also useful in the innovation. Maccarthy et al, in US Patent Application Serial No. 3 1,967 filed May 15, 1989, which is incorporated herein by reference, describe processes for oxidizing the surface of carbon fibrils that include contacting the fibrils with an oxidizing agent including sulfuric acid (H2SO4) and potassium chlorate (KCl03) under reaction conditions (eg time, temperature and pressure) sufficient to oxidize the surface of the fibril. Fibrils oxidized according to the McCarthy et al. they are oxidized in a non-uniform manner, that is, the carbon atoms are substituted with a mixture of carbonyl, aldehyde, ketone, phenol groups and other carbonyla groups. Fibrils have also been non-uniformly oxidized by treatment with nitric acid. International Application PCT / US94 / 10168 discloses the formation of oxidized fibrils containing a mixture of functional groups. Hoogenvaad, M.S., et al. ("Metal catalysts supported in a Novel Carbon Support", Presented at the Sixth International Conference on the Scientific Basis for the Preparation of Heterogeneous Catalysts, Brussels, Belgium, September 1994) also found that it was beneficial in the preparation of precious metals supported in fibrils, first oxidize the surface of fibrils with nitric acid. Pretreatment with acid is a standard step in the preparation of noble metal catalysts supported on carbon where, given the usual sources of such carbon, it serves both to clean the surface of undesirable materials and to function it. In published work, McCarthy and Benipg (Polymer Preprints ACS Di. Of Polymer Chem. 30 (1) 420 (1990)) prepared derivatives of oxidized fibrils to demonstrate that the surface comprises several oxidized groups. The compounds that they prepared, f m Ih i dragons, esters of the roertic, talose salts, etc., were selected because of their analytical utility, for example, bright color, or because they present some other strong and easily identified and iferen iada signal. These compounds were not isolated and, unlike the derivatives described here, have no practical importance. While many uses were found for carbon fibrils and carbon fibril aggregates, as described in the aforementioned patents and patent applications, many different and important uses can develop if the fibril surfaces are operated. Functional func- tion, whether uniform or non-uniform, allows the interaction of func- tional fibrils with several substrates to form unique compositions of matter with unique properties and allows the generation of fibrila structures in b links between the functional sites in the surfaces of the fibrils. OBJECTS OF THE INVENTION It is therefore a primary object of this invention to provide functional fibrils, ie, fibrils whose surfaces are uniformly or not uniformly modified such that they have a functional chemical moiety associated therewith. A further and related object of this invention is to provide fibrils whose surfaces are operated by reaction with oxidizing means or other chemical means. It is a further and related object of this invention to provide fibrils whose surfaces are uniformly modified either by means of a chemical reaction or by means of physical absorption of species which themselves have a chemical reactivity. It is an additional object to provide fibrils whose surfaces have been modified, for example, by oxidation, which are then modified adi cially by reaction with functional groups. It is a further and related object of this invention to provide fibrils whose surfaces are modified with a spectrum of functional groups in such a way that the fibrils can chemically react or can be physically bound and chemical groups in vr-ios substrates It's another additional object <; The present invention provides complex structures of fibrils by linking functional groups on the fibrils together from a range of chemical linkers. It is a further related object of this invention to provide methods for the chemical modification of fibril surfaces and methods for the physical absorption of species on the surface of fibrils to provide, in each case, a functional portion associated with the surface of the fibrils. the fibril. It is a further object of this invention to provide new co-factors of matter based on fibr the functionalities.

The majority of the carbon atoms in the surface layer of a graphitic fibril, as in graphite, are basic planar carbons. The flat carbons b salts are relatively inert to chemical attack. At deflection sites where, for example, the graphite plane is not eroded completely around the fibril, there are carbon atoms analogous to the carbon atoms of a graphite plane (see Urry, Ele entary Equilibrium Che istry of Coal, Wiley, Nem Yorfc 1989) for a discussion of the edge plane and basal carbons). At defect sites, the edge plane or basal carbons of the lower, inner layers of the nanotube may be exposed. The term surface carbon includes all the carbons, of basal plane and edge, of the outermost layer of the nanotube, as well as the carbons, both of the basal plane and / or edge, of the lower layers that may be placed in the defect sites of the outermost layer.

The preferred cylindrical compounds are flat acros in accordance with what is described on page 76 of Cotton and Will.nsou, Advanced Organic Chemicals (Advanced Organic Chemistry). The most preferred cyclic compounds for adsorption are the porphyrins and the phosphates. The adsorbed cyclic compounds can be functionalized. Such compositions include compounds of the formula (CnHL * (X-Aa) m where m, rt, L, a, X and A are as defined above and the carbons are surface carbons of a 1 cylindrical substance graphitic nanotube segelen described above, the fungal carbon fibrils in accordance with the above described can in order to be in a matrix. Preferably, the matrix is an organic polymer (for example, a thermosetting resin such as an epoxy resin, of b i a lei a, pol lide, or pali; a thermoplastic resin or a resin molded by reaction injection; or an elastomer such as, for example, natural rubber, rubber, styrene-butadiene, or cis-1,4-polybutylene); an inorganic polymer (for example, polymeric inorganic oxide such as glass), a metal (for example lead or copper), or a ceramic material (for example Portland cement). Without subjecting ourselves to any particular theory, fungal fibrils are better dispersed in polymeric systems because the modified surface properties are more cohesive. The polymer or the modified functional groups (particularly hydrophilic or amine groups) are bonded directly onto the polymer as terminal groups. In this way, polymer systems such as polycarbonate, polyurethane, polyesters, or polylaids / imides are bonded directly onto the fibrils, making the fibrils easier to disperse with better adhesion. The invention is also in relation to methods for introducing functional groups on the surface of carbon fibril by contacting carbon fibrils with a strong oxidizing agent for a period of time sufficient to oxidize the surface of said fibers. fibrils and puts into contact said fibrils with appropriate reactive urt to add a functional group to the oxidized surface. In a preferred embodiment of the present invention, the oxidizing agent is formed from a solution of an alkali metal chlorate in a strong acid. In other embodiments of the invention, the alkali metal lorate is sodium chlorate or potassium chlorate. In preferred embodiments, the strong acid employed is sulfuric acid. Sufficient periods of time for 1-oxidation are approximately 0.5 hours to approximately 24 hours. The invention also relates to methods for the production of carbon fibrils which comprises contacting carbon fibrils with an oxidizing agent for a sufficient period of time to oxidize the surface of the carbon fibrils. , the contacting of surface-oxidized carbon fibrils with suitable reagent to add a functional group to the surface of carbon fibrils, and the additional contacting of surface functionalized fibrils with an effective cross-linking agent to produce a network of carbon fibrils. A preferred crosslinking agent is a polyol, polya ida or p l i acid. ar bo. 11 ico. Functional fibrils are also useful for rigid fibril preparations. A well-dispersed three-dimensional network of fibrils funeted by acid can, for example, be stabilized by crosslinking the acid groups dnterf ibri) with polyols or polyamines to form a rigid network. The invention also includes three-dimensional networks formed by linking functionalized fibrils of the invention. These complexes include at least two fungal fibrils linked by one or more linkers comprising a direct bond or a chemical moiety.
E- > The networks comprise porous media of remarkably uniform equivalent pore size. They are useful as adsorbents, catalyst supports, and media. Although the interstices between these fibrils are irregular both in size and shape, they can be considered as pores and characterized by the methods used to characterize the media. porous The size of the interstices in such networks can be controlled by the concentration and level of dispersion of fibrils, and the concentration and chain lengths of the crosslinking agents. Such materials can act as structured catalyst supports and can be prepared to exclude or include molecules of 5 ci Ho size. From conventional industrial catalysis, they have special applications as large pore supports for biologically insulated vessels. Rigid networks can also serve as a structure in < ") b io i ethic systems for molecular recognition, systems have been deciphered in U.S. Patent No. 5,110.83", and in International Patent Publication No. W093 / 19344. Appropriate selections for crosslinking agents and complexing agents allow for the establishment of specific molecular structures.
METHODS FUNCTIONAL FARO IZAR FIBRILAS The fibrils uniformly funeled by the invention can be prepared directly by sulphonation, addition of elefofil on surfaces of deoxygenated surfaces or metalization. When nanofibers that grew in arc are used, they may require extensive purification before the operation. Ebbesen et al. (Nature 367 519 (1994)) provide a method for purification. Preferably, the carbon fibrils are processed before they are brought into contact with the func tioning agent. Such processing may include dispersing the fibrils in a solvent. In such cases, carbon fibrils can be filtered and dried before further contact. 1. THE FONATION The background of the technique is described in March, J.P., Ad vaneen Organic Chemistry, (Advanced Organic Chemistry), 3rd. edition, Wiley, New Yor * i, 1985; House; H., Modern Synthetie Reactions, (Modern Synthetic Reactions), 2nd. edition, Be jami n / Cummings, Menlo Par! , CA 1 * 972. Activated C-H bonds (including aromatic C-H) can be sulfonated using fuming sulfuric acid (pi r-osul furic acid), which is a concentrated sulfuric acid solution containing up to 20% S03. The convention method is by means of the liquid phase at a temperature of approximately 80 * C using p i rosul acid; however, activated C-H bonds can also be sulphonated using S03 in aprotic, inert solvents or S03 in the vapor phase. The reaction is: -C-H + SP3 - > -C-S03H The overreaction results in the formation of sulfones, in accordance with the reaction: 2-C-H + SP3 > -C-S02-C- + H20 EXAMPLE 1 Activation of C-H bonds using Sulfuric Acid Reactions were performed in the gas phase and in solution without any difference in ignition in terms of results. The reaction in the vapor phase was carried out in a reactor of a water reactor heated by a furnace i i d ertj. A multi-neck row containing S03 to 'A in H2S04 concentrate equipped with gas inlet / outlet tube = was used as a source of S03. A weighted example of fibril (BN or CC) in a porcelain container was placed in the 2.54 cm tube equipped with a gas inlet. The outlet was connected to a concentrated H2S04 bubble apparatus trap. It was purged with argon in the reactor for 20 minutes to remove all the air, and the sample was heated at 300 ° C for 1 hour to remove residual moisture. After drying, the temperature was adjusted to reaction temperature under an argon atmosphere. When the desired temperature was stabilized, the S03 source was connected to the reactor tube and an argon current was used to carry the S03 vapors from the quartz reactor. The reaction was carried out for the desired time at the desired temperature, after which the reactor was cooled with argon flows. The fibrils were then dried at 90 ° C and in a vacuum of 12.7 cm Hg to obtain the weight gain in the dry state. The sulphonic acid content (-S03H) was determined by the reaction with 0.100N NaOH and a new titration was carried out with 0.100N HCl using oH 6.0 co or end point. The liquid phase reaction was carried out in concentrated sulfoic acid containing% S03 in a 100 c multi-neck flask equipped with a thermometer / temperature controller and a magnetic stirrer. A fibril paste in concentrated H2SO4 (50) was placed in the flask. The acid solution p i rasu 1 f rich C2 <; zc was preheated to approximately 60 * C before its addition to the rea tor. After the reaction, the acid paste was emptied with ice or ice, and diluted immediately with one liter of water. The solids were filtered and washed thoroughly with deionized water until no change in the pH of the wash effluent was observed. The fibrils were dried at 100 ° C under a vacuum of 12.7 cm Hg. Due to the loss of transfer upon filtering, precise weight gains could not be obtained. The results appear in Table 1. Table I Summary of reactions EXAMPLE NO.

An effect of temperature was observed. A higher reaction temperature (f is steam) provides higher amounts of sulfonis. In 118-61B, the gain of 4.2% by weight corresponded to the sulfonic acid content (theoretically O. 51 meq / g). Experiments 60A and 61A showed too high a weight gain so that it can be assigned only to the sulfonic acid content. It was therefore considered that appreciable amounts of sulfones were also developed. 2. ADDITIONS TO THE SURFACES OF FIBRILLS EXEMPT FROM OXIDE In Urry, G., Elementary Equilibrium Chemistry of Carbon (Chemistry of Elemental Balance of Carbon), Wiley, New York, 1989, background techniques are described. The superficial carbons in the fibrils behave like graphite, that is, they are arranged in hexagonal sheets containing both basal plane carbons or edge carbons. While flat-carbon carbons are relatively inert to chemical attacks, the edge carbons are reactive and must contain some heteroatoms or groups to satisfy the valence of the carbon, the fibrila-, they also have super defect sites. -f i > The most common atoms fixed on the surface carbons of fibrils are hydrogen, the predominant gas component during manufacture, oxygen due to its high reactivity, which are basically the edge carbons and contain heteroatoms or groups. and because it is very difficult to avoid traces of the element, and water, which is present at the first time due to the catalyst, pyrolysis to a turbine in a deoxygenated vacuum in the surface of a complex reaction with unknown mechanisms, but This product is known as CO and C02, in a 2 1 -project. The resulting fibril surface contains radicals in a C1-C4 alignment that are highly reactive with activated olefmas.The surface is stable in vacuum or in the presence of an inert gas, but maintains its reactivity until it is exposed to a reaction gas, therefore, the fibrils can be picolized at a temperature of Properly IOOO'C in a vacuum or in an inert atmosphere, cooled under these conditions and with a suitable molecule at all times. to your * lower for p i oror > ar un giupo fune luna! stable.

The tube ends are equipped with gas inlet / outlet. Under continuous flow of H2, the fibrils are heated at 700 ° C for 2 hours to convert any surface oxygenate into C-H bonds. The reactor was then cooled to room temperature under H2 flow. The hydrogenated fibrils are transferred with dry, dehydrogenated heptane (with LY1H4) to a 1 liter, multi-necked round bottom flask equipped with a purified argon purge system to remove all air and matert an inert atmosphere, a conden- , a magnetic stirrer and a bule septum through which liquid can be added by means of a syringe. Under an argon atmosphere, a 2 * 4 solution containing 5 butyl lithium is added via syringe and the paste is shaken under gentle reflux for 4 hours. At the end of this period, the fibrils are separated by gravity filtration in an argon atmosphere glove and washed several times on the filter with heptane de-so. igenado, dry. The fibrils are transferred to a 50 c round bottom flask equipped with a stopper and dried under a vacuum of 1 / 10,000 tsrr at 50 * C. The lithium concentration is determined by the reaction of a sample of fibrils with excess O.IOON HCl in deionized water and re-titration with O.IOON NaOH to a final point with pH 5.0. EXAMPLE 7 Preparation of fibrila-Tl (TFA12 One gram of CC fibrils is hydrogenated as in example 5 and loaded into the multi-neck flask with HTFA that has been degassed by repeated purging with dry argon. of 5 mmol of TI (TFA) 3 in HTFA is added to the flask through the rubber septum and the paste is shaken under gentle reflux for 6 hours After the reaction the fibrils are collected which are dried as in example 1. EXAMPLE 8 Preparation of fibrila-OH (oxygenated derivative containing only functional OH-ionization) Half gram of lithiated fibrils prepared in Example 6 are transferred with undigested heptane, dried in a glove bag of alcohol atmosphere to a neck flask single 50 c equipped with a cap and magnetic stir bar The bottle is removed from the glove bag and shaken on a magnetic stirrer The plug is *, 33 then open to the air and the paste is stirred for 24 hours. At the end of this time, the fibrils are separated by filtration and washed with aqueous MeOH, dried at 50 ° C and under a vacuum of 12.7 cm. The concentration of OH groups is determined by reaction with a standardized solution of acetic anhydride in dioxide (0.252 M) at 80 ° C to convert the OH groups into acetate esters, and in this way, release 1 equivalent of acetic acid / mol of reacted anhydride. The amount of total acid, free acetic acid and unreacted acetic anhydride is determined by titration with NaOH O.IOON to a final point at a pH of 7.5. EXAMPLE 9 Preparation of Fibila-NH2 A gram of felled fibrils is prepared as in Example 7. The fibrils are pulped in dioxane and 0.5 g of dihydroxyphosphine is added in dioxane. The paste is stirred at 50 ° C. for several minutes, followed by the addition at 50 ° C. of gaseous ammonia for 30 minutes. The fibrils are then separated by filtration, washed in diaxapo, then in deionized water and dried at 80 ° C. in a vacuum of 12.7 cm. The. Amine concentration is determined by reaction with an excess of acetic anhydride and a re-titration of free acetic acid and unreacted anhydride with NaOH O.IOON. 4. AROMATIC COMPOUNDS POLY UCLE REAS DERIVATIVES, COMPOUNDS ARROATIC POLYHETERONUCLEARS DERIVATIVES AND DERIVED FLAT MACROCYCLICAL COMPOUNDS The graffiti surfaces of fibrils allow the physical adsorption of aromatic compounds. The attraction is realized through the van der Waals forces. These forces are considerable between multiple-ring heteranuclear aromatic compounds and the carbons of the basal plane of the graphite surfaces. Desorption can occur under conditions where competitive surface adsorption is possible or when the adsorbate has a high solubility. EXAMPLE 10 Adsorption of porphyrins and phthalocyanins in fibrils The preferred compounds for physical adsorption in fibrils are derived particles or phthalic derivatives known to be strongly adsorbed on graphite or carbon black. Several compounds are available, for example, a tetracarboxylic acid porphyrin, cobalt (II) phthalocyanine or di lithium phthalacyanine. The last two compounds can be derived in the form of carboxylic acid. The loading capacity of the porphyrin or of more phthalocyanines can be determined by decolorizing the solutions when they are added incrementally. The .7 dark colors of the solutions (dark pink for the porphyrin of tetracarboxylic acid in MeOH, dark blue-green in the case of Co (II) or of the phthalocyanine of dilithium in acetone or pyridine) are discharged according to the molecules they remove by adsorption on the black surface of the fibrils. The loading capacities were estimated by this method the traces of the derivatives were calculated from approximate suspensions (approximately 140 square Angstroms). For an average surface area of fibrils of 250 m2 / g, the maximum load will be approximately 0.3 mntol / g. The porphyrin of tetracarb acid i 1 ico was analyzed by titration. The integrity of the adsorption was tested by color release in aqueous systems at room temperature and at elevated temperatures. The fibril pastes were initially mixed (W ring mixer) and stirred during loading. Some of the pulps were subjected to ul trasonido after the suspension of the color discharge, but without effect. After loading, experiments 169-11, -12, -14 and -19-1 (see Table II) were washed in the same solvent to remove the occluded pigment. All provided a continuous weak ink in the wash effluent, such that it was difficult to determine the saturation point accurately.
Experiments 168-18, and - 19--2 used calculated amounts of pigments to load and were washed only very slightly after ca.ga. The porphyrin of tetracarboxylic acid (from acetone) and phthalocyanine Co (from pyridine) were loaded into fibrils for further characterization (experiments 169-18 and -19-2, respectively). Porphyrin analysis of tet racarboxylic acid The addition of excess base (pH 11-12) caused an immediate pink coloration of the titration paste. While this did not interfere with the figuration, it was shown that at a high pH level, the porphyrin exhibited desorption. The concentration of carboxylic acid was determined by re-titrating excess NaOH using pH 7.5 as the end point. The titration provided a load of 1.10 meq / g of acid, equivalent to. 75 meq / g of porf i r i na. Analysis of cobalt or phthalocyanine of dilithium The concentrations of these adsorbates were estimated from de-colouration experiments only. The point where the blue-green ink did not fade after -30 minutes was taken as the saturation point. Numerous polynuclear substituted aromatic compounds or ai-omát i > : -'-) pol and substituted heteronucleres were adsorbed on fibril surfaces. Par-to his adhesion, the? The aromatic rings must be greater than two per functional pendant ring, and therefore substituted, substituted, substituted phenothianes, etc., with three fused rings, or poly-functional derivatives with four or more. more fused rings can be used in place of the porphyrin or of the derivatives of phthalocytes, in the same way, heterocyclic substituted aromatics as for example quinolines, or romanic compounds several times substituted Those containing four or more rings may be used Table II presents the results of the loading experiments for the three derivatives of porf i rirta / f ta loe iani na TABLE II SUMMARY OF ADSORPTION EXPERIMENTS Example Addebate Experiment » Weight of Sun.

NITRIC ACID OXIDATION 0 CHLORATE The literature on the oxidation of graphite by strong oxidants such as, for example, potassium chlorate in concentrated sulfuric acid or in concentrated nitric acid, includes R.N. Smith, Gjuarterly Review 13, 287 (1959) j M.J.D. Low, Chem. Rev. 60, 267 (1960)), Generally, edge carbons (including defective sites) are attacked to provide mixtures of carboxylic acids, phenols, and oxygenated groups. The mechanism is complex and involves radical reactions. EXAMPLE 11 PREPARATION OF FUNCTIONAL FIBRILLS BY CARBOXY L ACID USING CHLORATE The sample of CC fibrils was formed into paste in concentrated H2SO4 by mixing with a spatula and then transferred to a "reactor" bottle equipped with an inlet / outlet. gas and an agitator on top.
Under agitation and with a slow flow of argon, the charge of NaC103 was added, in parts at room temperature during the period of the experiment. Chlorine vapors were generated throughout the course of the experiment which were removed from the reactor in a tranche of aqueous NaOH. At the end of the experiment, the fibril paste was emptied into ice chips and filtered in vacuum. The filter cake was then transferred to a Soxhlet thimble and washed in a Soxhlet extractor with deionized water, changing the clean water every several hours. The washing was carried out continuously until the fibril sample, when added to fresh deionized water, did not lose the pH of the water. The fibrils were then separated by filtration and dried at 100 ° C overnight under a 12.7 cm vacuum.
Carbohydric acid content was determined by reacting a sample with an excess of 0.100 N NaOH and re-titrating with O.lOOn HCl to a final point at a pH of 7.5. The results appear in the Table.

Under constant agitation, the temperature was adjusted and the reaction was carried out for the specified time. Brown fumes were released shortly after the temperature exceeded 70 ° C, regardless of the strength of the acid. After the reaction, the paste was emptied in t-ice ice and diluted with deionized water. The paste was filtered and the excess acid removed by washing in a Saxhlet extractor, replacing the reserve with fresh deionized water every several hours, until the sample in paste form did not change the pH of the deionized water. The fibrils were dried at 100 ° C overnight in a 12.7 cm vacuum. A weighted portion of fibril was reacted with standard O.sub.100 N NaOH and the carboxylic acid content was determined by re-titration with 0.100 N HCl. The surface oxygen content was determined by XPS. The dispersion capacity in water was tested at 0.1% by weight by mixing in a Waring blender at high speed for two minutes.

SECONDARY DERIVATIVES OF LIFTED FUNCTIONAL FIBRILLES Fibrils functionalized by carboxylic acid The number of secondary derivatives that can be prepared from only carboxylic acid is essentially unlimited. Alcohols and amines are easily linked with acid to provide stable esters or stable amides. If the alcohol or amine is part of a difunctional or functional psi molecule, then the link through 0- or NH- leaves the other functionalities as hanging groups. Typical examples of secondary reagents are: GENERAL FORMULA GROUP EXAMPLES PENDANT HO-P, P = alkyl, P-methanol, phenol, trifluoro-aralkyl, aryl, carbon, polyester with f-haloethanol, OH-termination, polymer silanols, SiR'3 H2N-R R = as R-amines, anilines, to inírß up fluorinated, silylamine * «polyamides with amine termination C1-SiR3 SiR3- c lorosi l nos HO-R-OH, Realkyl, HO- and i-glycol, PEG, penta-aralkyl, CH20-erythritol, bis-phenol A H2N-R-NH2, H2N- eti lendiamine, polyethyl-R = aralkyl alkyl endiami X-R-Y, R = alkyl, Y-polyamine amides, etc? X = OH or NH2? mercaptoet nol Y = SH, CN, C = 0, CHO, alkene, aromatic, heterocycles The reactions can be carried out using any of the methods developed to esterify or amines carboxylic acids with alcohols or amines. Among these, the methods of H.A. Staab, Angew, Chem. Internat, Etit., (1), 351 (1962) using N, N'-carboni ldi imidazole (CDI) as an acylating agent for esters or amides, and of G.W. • Ire Anderson, et al., J. Amer. Chem. Soc. 86, Í839 (1964), using N-hydroxysuccinimide (NHS) to activate carboxylic acids for amidation. EXAMPLE 13 PREPARATION OF SECONDARY DERIVATIVES OF FIBRILLES FUNCTIONALIZED N, N'-carboni ldi imidazole Aprotic, dry, clean solvents (eg, toluene or dioxide) are required for this procedure. Stoichiometric quantities of reagents are sufficient. For steres, the carboxylic acid compound reacts in an inert atmosphere (argon) in toluene with a stoichiometric amount of CDI dissolved in toluene at room temperature for two hours. During this time, C02 is issued. After 2 hours, alcohol is added together with catalytic amounts of Na-ethoxide and the reaction proceeds to BO'C for 4 hours. In the case of normal alcohols, the yields are quantitative. The reactions are: 1. R-C00H + Im-Co-Im > R-CO-Im + HIm + HIm + C02, Im = Imidazole gone, HIm = Imidazole NaOEt 2. R-CO-Im - + R'OH > R-C0-0R '+ HIm The amidation of the amines occurs in a non-catalyzed manner at room temperature. -The first step in the procedure is the same. After the emission of C02, a stoichiometric amount of amine is added at room temperature and the reaction is carried out for 1-2 hours. The reaction is quantitative. The reaction is: 3. R-CO-Im + R'BG2 > R-CO-NHR + HIm N-hydroxy isuccini ida The activation of carboxylic acids for primary amino-amine amines occurs through the M-hydroxysuccinamine ester; Carbonate is used to bind the released water as a substituted urea. The NHS ester is then converted to room temperature in the amide by reaction with primary amine. The reactions are: 1. R-COOH + NHS + CDI > R-CONHS + substituted urea 2. R-CONHS + R'NH2 r- > R-CO-NHR 'SILILATION Trialquilsi 1 i Ichlorides or trialkylsilanols react immediately with H acid in accordance with: R-COOH + Cl-Si' 3 > R-CO-SiR'3 + HCl Small amounts of Diaza-1, 1, 1, -bicyclooctane (DABCO) are used as catalysts. Suitable solvents are dioxane and toluene. EXAMPLE 14 PREPARATION OF ESTER / ALCOHOL DERIVATIVES FROM FIBRILLES FUNCTIONALIZED WITH CARBONOXY ACID Fibrils functionalized with carboxylic acid were prepared as in example 11. The carboxylic acid content was 0.75 meq / g. The fibrils reacted with a stoichiometric amount of CDI in an inert atmosphere with toluene as solvent at room temperature until the CO 2 emission was suspended. Thereafter, the pulp reacted at 80 ° C with a 10-fold molar excess of polyethylene glycol (molecular weight 600) and a small amount of NaOEt as a catalyst. After two hours of reaction, the fibrils were separated by filtration, washed with toluene and dried at 100 * C. EXAMPLE 15 PREPARATION OF AMID / AMINE DERIVATIVES FROM FIBRILLES FUNCTIONAL LIFTED WITH CARBOXYLIC ACID (177-041-1) 0.242 g of oxidized fibrils were suspended with chlorate (0.62 meq / g) in 20 ml of anhydrous dioxide under agitation in a 100 ml round bottom flask equipped with a stopper of serum. A 20-fold molar excess of N-hydroxysuccinimide (0.299 g) was added and allowed to dissolve. This was followed by the addition of a 20-fold molar excess of 1-et i 1-3- (3-dimet i laminoprop i 1) -carbodi ida (EDAC) (0.510 g) and the stirring continued for 2 hours at room temperature. ambient. At the end of this period the application was suspended, and the supernatant was aspirated and the solids were washed with anhydrous dioxane and MeOH and filtered on the polysulphone membrane of 0.45 microns. The solids were washed with additional MeOH on the filter membrane and dried in vacuum until no further weight reduction was observed. The yield of the oxidized fibrils activated with NHS was 100 * 4 based on the weight gain of 6 * 4 observed. 100 μl of ethendiamine (en) was added to 10 ml of NaH003.2 M regulator. An equivalent volume of acetic acid (HOAc) was added to maintain the pH around 8. Oxidized fibrils activated with NHS were added (0.310 g) under vigorous stirring and a reaction was carried out for 1 hour. An additional 300 μl of et i lendiamine and 300 μl of HOac were added for an additional 10 minutes. The solution was filtered on a 0.45 micron polysulfone membrane and selectively washed with NaHCO3 buffer, 1 * 4 HCl, deionized water and EtOH. The solids were dried under vacuum overnight. The HCl salt was converted back to the free amine by reaction with NaOH (177-046-1) for further analysis and reactions. ESCA was carried out to quantify the amount of N present in the aminated fibrils (GF / NH2). The ESCA analysis of 177-046-1 showed 0.90 to * 4 N (177-059). To additionally evaluate how much of this N is present in both reactive and reactive amine groups, a derivative was made by reaction in gas phase with pentaf luorobenzaldehyde to produce the corresponding Schiff base bonds with the available primary amine groups. The ESCA analysis still showed 0.91 at * 4 N, as expected, and 1.68 at * 4F. This is traduced in 0.34 at * 4 of N present as reactive primary amine in the aminated fibrils (5 F per molecule of pentaflurobenzaldehyde). It is expected that a level of 0.45 at'4 N assumes a complete reaction with the free ends of each N. The observed level indicates a very high yield from the reaction of N with fibrils acitvated with NHS and confirms the reactivity of the groups of free amines available. At the level of 0.34 at * 4 N present as free amine calculated from the ESCA data, there would be an almost complete coverage of the fibrils by the free amine groups allowing the coupling of other materials. EXAMPLE 16 PREPARATION OF SIL ILO DERIVATIVE APART FROM FUNCTIONALIZED FIBRILS BY CARBON ACID Organic acidic prepared fibrils prepared as in example 11 were formed in diaxana paste in an inert atmosphere. Under stirring, a stoichiometric amount of chloratinyllysilane was added and a reaction was carried out for 0.5 hours, after which several drops of a 5 * 4 solution of DABCO in dioxane were added. The system reacted for an additional hour, after which the fibrils were collected by filtration and washed in dioxane. The fibrils were dried at 100 * in a vacuum of 12.7 c during the night.

Sulfonic acids can be reduced to mercaptans by LIA1H4 or the combination of tri-phenylphosphine and iodine (March, J.P., page 1107). They can also be converted to sulfonate esters by reaction with dialkyl ethers, i.e., Fibrila-S03H + R-Qr-R > Fibrila-S020R + ROH Fibrils are activated by electrophysiological addition to oxygen-free fibril surfaces or by metalization The primary products that can be obtained by the addition of activated electrophiles to oxygen-free fibril surfaces have - COOH, -COCÍ, -CN, -CH2NH2, CH2CH, -CH2- halogen, or HC = 0 pendants.

Accordingly, the displacement of the Li + ions with a metal ion bound with non-labile ligands is a method for placing stable functional groups on the surfaces of fibrils. Almost all transition metal complexes displace Li + from Pe to form a stable, non-labile chelate. The point here is therefore to couple this metal with a suitable ligand, cobalt phthalocyanine < II) The cobalt (II) complexes are especially suitable for this. The Co ++ ion can be substituted by the two Li + ions to form a very stable chelate. The Co ++ ion can then be coordinated with urt ligand such as for example nicotinic acid, which contains a pyridine ring with a pendant carboxylic acid group and which is known to be preferably linked to the pyridine group. In the presence of excess nicotine acid, Co (II) Fe can be electrochemically oxidized in Co (III) Pe, forming a non-labile complex with the pyridine portion of nicotinic acid. Accordingly, the free carboxylic acid group of the nicotinic acid ligand is firmly fixed on the fibril surface. Other suitable ligands are aminopyridines or eti lendia inas (pendant NH2), ercaptopi ridine (SH), or other polypunctional ligands containing either an amino moiety or a pyridyl moiety at one end, and any desirable function in the other. 7. THREE-DIMENSIONAL STRUCTURES Oxidized fibrils are more easily dispersed in aqueous media than non-oxidized fibrils. Stable, porous, ridiculous structures with mesopors and macropores (pores of more than 2 nm) are very useful as catalysts or chromatography supports. Since the fibrils can be dispersed on an individualized basis, a well dispersed sample stabilized by crosslinks allows the construction of such support. Functional fibrils are ideal for this application since they can easily be dispersed in aqueous or polar media and the functionality provides crosslinking points. Additionally, the functionality provides points to support the catalytic points or cram tográf icos. The final result is a rigid, three-dimensional structure with its accessible total surface area with functional sites where the active agent can be carried. Typical applications for these supports in catalysis include their use as a highly porous support for metal catalysts placed by impregnation, for example precious metal hydrogenation catalysts. In addition, the ability to anchor molecular catalysts by means of bonding on the support through the functionality combined with the very high porosity of the structure makes it possible to carry out homogeneous reactions in a heterogeneous manner. The bound molecular catalyst is essentially suspended in the continuous liquid phase, similar to a homogeneous reactor, where the advantages of selectivities and velocities that accompany the homogeneous reactions can be used. However, since it is attached to the solid support this allows easy separation and recovery of the active catalyst and in many cases very expensive. These rigid, stable structures also make it possible to carry out reactions that were previously very difficult, such as for example asymmetric synthesis or affinity chromatography by fixing a suitable enantiomeric catalyst or selective substrate on the support. Derivation through metallo-Pe or metallo-porphyrin complexes also allows the recovery of the bound metal ligand, and in addition, of any molecule bound to the ligand through the secondary derivatives. For example, in the case in which the three-dimensional structure of fibrified func- tions is an electrode, or part of an electrode, and the functionalization resulted from the adsorption of Co (II) Pe, the electrochemical oxidation of Co ( II) in Co (III) in the presence of nicotinic acid will produce a Co (III) -pyridyl non-labile complex with a carboxylic acid as a pendant group. The attachment of an appropriate arttigene, antibody, catalytic antibody, or other suitable site-specific entrapment agent will allow selective separations of molecules (affinity chromate raffia) that are otherwise very difficult to achieve. After washing the electrode to remove the occluded material, the Co (II) complex containing the target molecule can be electrochemically reduced to recover the labile Ca (II) complex. The ligand in Co (II) containing the target molecule can then be recovered by mass-action substitution of the labile Ca (II) ligand, thus effecting a separation and recovery of molecules that are otherwise very difficult or costly to carry out (for example, chiral drugs). Another example of three-dimensional structures are fibril-ceramic composites. EXAMPLE 18 Preparation of alumina-fibril compounds (185-02-01) One gram of fibrils oxidized by nitric acid (185-01-02) was highly dispersed in 100 cc of deionized water using a U / S disintegrator. The fibril paste was heated to 90 ° C and a solution of 0.04 mol of aluminum tributhoxide dissolved in 20 g of propanol was slowly added. The reflux continued for 4 hours, after which the condenser was removed to remove the alcohol. After 30 minutes the condenser was returned and the pasta subjected to reflux at 100 ° C overnight. A black colloidal solution with a uniform appearance was obtained. The colloidal solution was cooled to room temperature and after one week, a black gel with a smooth surface was formed. The gel was heated at 500 ° C in the air for 12 hours. The alumina-fibril compounds were examined by SEM. Micrographs of cracked surfaces showed a homogeneous dispersion of the fibrils in the gel. EXAMPLE 19 Preparation of silica-fibril compounds (173-85-03) Two grams of fibrils oxidized by nitric acid (173-83-03) were highly dispersed in 200 g of ethanol using ul trasoni fica. A solution of 0.01 mol of tetraethoxysilane dissolved in 50 ce of ethanol was slowly added to the paste at room temperature, followed by 3 cc of concentrated HCl. The mixture was heated to 85 ° C and maintained at this temperature until the volume was reduced to 100 ° C. The mixture was cooled and stored until a solid black gel formed. The gel was heated at 300 ° C to the air. The ice-fibril compound itself was examined by SEM. The micrographs of the cracked surfaces showed a homogeneous dispersion of the fibrils in the gel. Similar preparations with other ceramics, such as zirconia, titania, rare earth oxides as well. as ternary oxides can be prepared.
