Definitions
- a wide variety of fibrous precursors can be employed in the process of this invention.
- suitable fibers include acrylics, polybenzimidazoles, nylons, and carbon fibers.
- acrylic fibers are known to the art, i.e. fibers formed from at least by weight acrylonitrile and up to 15% of monomers copolymerizable therewith.
- Preferred fibers of this class in the process of this invention are acrylonitrile homopolymers and that formed from 9394% by weight acrylonitrile and 67% by weight methyl acrylate.
- a preferred subclass of polybenzimidazole precursors for use in this invention consists of recurring units of the formula:
- R is an aromatic nucleus having each of the two depicted pairs of nitrogen atoms substituted upon adjacent carbon atoms of the said aromatic nucleus and R is a carbocyclic ring.
- poly-2,2-m-phenylene-5,5'-bibenzimidazole which consists of recurring units of the formula:
- the plating is carried out by continuously passing the precursor fiber through a stannous chloride solution and then through a solution containing a salt of a noble metal to form a thin film of the noble metal thereon. Thereafter the sensitized fiber is passed through a basic aqueous formaldehyde solution containing chelated cupric ions to form a thin copper coating. This copper-coated fiber is then electroplated by placing a voltage drop across the fiber and passing the fiber through a suitable copper solution to produce a fine grained plating of sufficient conductivity for further processing.
- the preferred noble metal salt is a water-soluble silver salt such as silver nitrate. Salt of gold, platinum, rhodium and palladium can also be employed.
- the basic formaldehyde solution should have a pH in the range of 10 to 14.
- Suitable basic reagents are metallic and quaternary ammonium hydroxides such as sodium, potassium, calcium and tetramethylammonium hydroxide and the like.
- Suitable copper chelating agents include tartrates, salicylates, ethylenaminoacetic acids, alkanol aminoacetic acids and alkanolamines. Many such chelating agents are described in greater detail in US. Patents Nos. 2,874,072; 2,996,408 and 3,075,855.
- the copper sheaths resulting from this electroless deposition cannot be directly employed as an electrically conductive medium. They tend to flake and upon pyrolysis form hot spots and burn off. Furthermore, a residence time on the order of one hour would be required to produce a plating having sufiicient conductivity to effect a temperature of even 900 C.
- the electrodeposition can be conveniently carried out by passing the electrolessly plated fiber over a graphite roll into a solution containing soluble cupric salts such as copper sulfate.
- a copper bar is immersed in the bath and a voltage drop is maintained between the graphite roll and the bar.
- the residence time in the bath should be on the order of 2 minutes.
- the amount of copper electrodeposited should be sufficient to conduct enough current to effect a temperature of at least 900 C. and preferably 1000 C. This generally requires an amount of copper of between to 50%, and preferably 30 to 50%, by weight, of the weight of the organic fibrous precursor.
- the plated yarn is then pyrolyzed by placing a voltage drop across it. By adjusting this voltage drop, any desirable temperature profile may be obtained.
- the plated yarn is passed between two graphite rolls which in addition to guiding and transporting the yarn, form the two rotating terminals for the input of electrical power.
- the heating of the yarn may be conducted in N stages between N+1 rolls. By adjusting the voltage inputs between neighboring rolls, any desired temperature profile along the fiber may be attained.
- the voltage is regulated to effect a temperature of about 1000 C. and then the copper plating is removed. This removal can be effected simply by washing in a bath of nitric acid from Which the copper can later be recovered.
- the plating yarn is simply heated up in the same manner to within the range of 2000 to 3000" C.
- the copper plating will evaporate and can be suitably condensed on a cold surface, dissolved in acid and reused.
- the plateless carbon yarn is itself capable of conducting current and thus can be directly heated to form graphite yarn. It is preferable, however, not to remove the metal sheath since the metal sheath provide reinforcing action upon the still weak carbonaceous substrate. On subsequent heating to higher temperatures, the carbonaceous substrate is converted to fibrous graphite of considerably increased strength.
- the pyrolysis reaction is carried in inert environment, preferably nitrogen.
- EXAMPLE PBI yarn having the properties indicated below is pressed through a bath containing 10 grams of stannous chloride dihydride per liter, 20 mls. of concentrated hydrochloric acid per liter, and 1 ml. per liter of Aquet (non-ionic detergent-Monostat Corporation) in deionized water. The residence time is one minute. The yarn is then passed through a second bath containing 10 grams of silver nitrate per liter for a residence time of 1 minute and a thin film of silver forms.
- This yarn is then passed through a third bath containing 25 grams of copper sulfate pentahydrate per liter, 25 grams of triethanolamine per liter, 25 grams of formaldehyde (37%) per liter and 25 grams of sodium hydroxide.
- the bath has a pH of 12.
- the residence time in this bath is 3 minutes.
- the copper plated yarn is then passed over a graphite roll and through a fourth bath containing a copper bar, grams of copper sulfate pentahydrate per liter, 30 grams of sulfuric acid per liter and 10 grams of phenol per liter. 1.5 volt DC. potential is maintained across the graphite roll and the copper bar. After a residence time in this bath of 2 minutes, a fine grained copper-plated yarn is achieved.
- the plated yarn is passed over two motor driven graphite rolls separated from each other by about 4 inches.
- the electrical power is supplied from a volt/ 15 amp alternating current source and carried to the rolls via spring loaded graphite brushes.
- the voltage, and consequently the temperature, is regulated with a Variac located between the source and brushes.
- the voltage is adjusted to achieve a temperature of 1000 C.
- a yarn sample A is removed at this point and the plating is removed by washing in concentrated nitric acid.
- the remainder of the plated yarn (Sample B) is heated by means of the same graphite roll system to 2800 C.
- the plating evaporates and need not be chemically removed.
- the properties of the yarns are as follows:
- a process for the production of high temperature resistant car-bonaceous yarns comprising the steps of (1) forming thin films of sensitizing and activating metals on the surface of an organic fiber, (2) electrolessly plating a thin layer of copper on the activated surface, (3) electrodepositing additional copper on top of said copper layer and (4) passing an electric current across said plated fiber to effect temperatures of at least 900 C.
- a process according to claim 1 wherein the amount of said additional copper electrodeposited is equivalent to between 10 to 50% by weight of the weight of said organic fiber.
- a process according to claim 10 wherein the pH of said solution is from about 10 to 14.
- a process according to claim 11 wherein the amount of said additional copper electrodeposited is equivalent to between 30 to 50% by weight of the said organic fiber.
