Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a method for preparing a carbon nanotube composite structure. [0002] 先前 [Prior Art] A carbon nanotube is a hollow tube rolled from a graphene sheet. Nano carbon tubes have excellent mechanical, thermal and electrical properties and are used in a wide range of applications. For example, carbon nanotubes can be used to make field effect transistors, atomic force microscope tips, field emission electron guns, nano templates, and the like. The application of the carbon nanotubes in the above technology is mainly the application of the carbon nanotubes on the micro scale, and the operation is difficult. Therefore, it is important to make the carbon nanotubes have a macroscopic structure and to be applied at a macroscopic level. [0003] Jiang Kaili et al. successfully obtained a nano carbon pipeline from a carbon nanotube array in 2002, see the literature "Spinning Continuous Carbon Nanotube Yarns", Nature, V419, P801. The nanocarbon pipeline is composed of a plurality of carbon nanotubes connected end to end and arranged in a preferred orientation in the same direction. [0004] However, the bonding strength between the carbon nanotubes in the nanocarbon pipeline is weak, so the mechanical strength of the nanocarbon pipeline needs to be further improved. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a method for preparing a carbon nanotube composite structure for preparing good mechanical properties. [0006] A method for preparing a carbon nanotube composite structure, comprising the steps of: dissolving a polymer in an organic solvent to form a polymer solution, the contact angle of the organic solvent to the carbon nanotubes is less than 90 degrees; And a carbon nanotube structure of a support structure from 099122580 Form No. A0101/3/36 pages 0992039782-0 201202318 is impregnated in the polymer solution to composite the polymer with the carbon nanotube structure. [0010] [0013] [0013] [0013] 099122580 A method for preparing a carbon nanotube composite structure, comprising the steps of: dissolving a polymer monomer in an organic solvent to form a polymer monomer solution having a contact angle of less than 90 degrees to a carbon nanotube; infiltrating a self-supporting structure of a carbon nanotube structure in the polymer monomer solution; and allowing the polymer The polymer monomers in the monomer solution polymerize with each other to form a polymer and are combined with the carbon nanotube structure. Compared to the prior art, the carbon nanotube composite structure dissolves the polymer by selecting an organic solvent having a contact angle of less than 90 degrees to the carbon nanotube, thereby enabling the polymer to be sufficiently wetted in the nanometer. In the carbon nanotube film structure, it is tightly bonded to the carbon nanotube. Thereby, the carbon nanotube composite structure prepared by the method has excellent mechanical properties. [Embodiment] Hereinafter, the present invention will be described in further detail with reference to the accompanying drawings. A method for preparing a carbon nanotube composite structure according to a first embodiment of the present invention includes the following steps: S10, dissolving a polymer in an organic solvent to form a polymer solution, wherein the organic solvent is on a carbon nanotube The contact angle is less than 90 degrees; and S20, a carbon nanotube structure of a self-supporting structure is impregnated into the polymer solution to composite the polymer with the carbon nanotube structure. In the step S10, the type and nature of the polymer are not limited and may be selected according to actual needs, and only need to be dissolved in the organic solvent. The polymer may include polyacrylonitrile (PAN) Form No. A0101 Page 4 / Total 36 Page 0992039782-0 201202318 ρ P〇lyvinyl alcohol (PVA), Polypropylene (p^mQPylene', Polystyrene (Polystyrene, Polyvinylchlorid, PVC and Polyparaphenylene)

Generally, when the polymer is polyvinyl alcohol 2, the degree of polymerization of the polyethylene glycol is between 15 Å and 35 Å. The mass percentage of the polymer in the aggregating liquid varies depending on the polymer and the organic solvent [0014]. Generally, when the polymer is polyvinyl alcohol, the mass percentage of the poly(ethylene) dilute alcohol is approximately between 1% and ^ such that the polyvinyl alcohol solution is wetted in the nano. It is sufficient to reduce the specific surface area of the carbon nanotube structure as much as possible. The organic refrigerant is used to dissolve the polymer and can be immersed with the carbon nanotube to enable the polymer to be fully immersed - even infiltrating into the carbon nanotube structure The inside of the carbon nanotube in the structure can be dipped into the hollow portion of the carbon tube. Preferably, the organic solvent has a relatively large surface tension while being capable of dissolving the polymer. Specifically, the organic solvent may have a surface tension of more than 20 millinews per meter and a contact angle to the carbon nanotubes of less than 9 degrees. The organic solvent includes Dimethyl Sulphxide (DMS0), monomethymamine (j) imethyi Formamide (DMF), 2, 5-methyl 11 fumon (2, 5-dimethyl). Any one or combination of furan) and N-methyl-n-pyrrolidone (N-methyl-2-pyrr〇iici〇ne, ΝΜΡ). Since the dissolving power of the organic solvent differs depending on the polymer, the choice of the organic solvent is determined according to the specific polymer, depending on the polymer, the number of the polymer, the number of the organic solvent, and the number of the organic solvent. For example, when the polymer is polyvinyl alcohol, the organic solvent may be selected from the group consisting of dimercaptopurine. The surface tension of the dimethyl hydrazine is approximately 43.54 milli-Nilometers per meter and the contact angle to the carbon nanotubes is approximately 70 degrees. The contact angle of the organic solvent to the carbon nanotubes is an angle complementary to the wetting angle of the organic solvent to the carbon nanotubes. The smaller the contact angle of the organic solvent to the carbon nanotubes, the better the wettability of the polymer to the carbon nanotube structure, and the closer the polymer is bonded to the carbon nanotube structure. The greater the surface tension of the organic solvent, the better the wettability of the polymer to the carbon nanotube structure, the stronger the ability to shrink the structure of the carbon nanotube, the polymer and the naphthalene The tighter the carbon nanotube structure is combined. [0015] The carbon nanotube structure is a film-like structure, a linear structure or other three-dimensional structure composed of a plurality of carbon nanotubes. The carbon nanotube structure is a self-supporting structure of a carbon nanotube, and the so-called "self-supporting" means that the carbon nanotube structure does not need to be supported by being disposed on a surface of the substrate, that is, the edge or the opposite end is not supported. The rest of the part can maintain its own specific shape. Since a large number of carbon nanotubes in the self-supporting carbon nanotube structure are attracted to each other by Van der Waals attractive force, the carbon nanotube structure has a specific shape to form a self-supporting structure. . Generally, when the distance between the plurality of carbon nanotubes in the carbon nanotube body is between 0.2 nm and 9 nm, there is a large van der Waals force between the carbon nanotubes. Thereby the carbon nanotube structure is formed by the van der Waals force to form the self-supporting structure. [0016] The carbon nanotube structure may include at least one carbon nanotube film, when the nai 099122580 form number A0101 page 6 / 36 pages 0992039782-0 201202318 m carbon tube structure includes a plurality of carbon nanotubes In the case of the membrane, the plurality of carbon nanotube membranes are disposed, and the adjacent carbon nanotube membranes are combined by van der Waals force. [0017] Referring to FIG. 1, the carbon nanotube structure film may be a carbon nanotube flocculation film, and the carbon nanotube film is a carbon nanotube raw material, such as a super-aligned array. The flocculation treatment obtains a self-supporting carbon nanotube structural film. The carbon nanotube flocculation membrane comprises carbon nanotubes which are intertwined and uniformly distributed. The length of the carbon nanotubes is greater than 10 microns, preferably from 200 microns to 900 microns, thereby entwining the carbon nanotubes with one another. The carbon nanotubes are attracted to each other by van der Waals forces to form a network structure. Since the large number of carbon nanotubes in the self-supporting carbon nanotube flocculation membrane are mutually attracted and intertwined by van der Waals force, the carbon nanotube flocculation membrane has a specific shape to form a self-supporting structure. . The carbon nanotube film is isotropic. The carbon nanotubes in the carbon nanotube flocculation membrane are uniformly distributed and randomly arranged to form a large number of gaps or micropores having a size ranging from 1 nm to 500 nm. 5纳米至100微米之间。 The carbon nanotubes of the film is not limited in area and thickness, the thickness is between about 0.5 nm to 100 microns. [0018] The carbon nanotube structure film may be a carbon nanotube rolled film, which is a self-supporting nano-particle obtained by rolling a carbon nanotube array. Carbon tube structural film. The carbon nanotube rolled film comprises uniformly distributed carbon nanotubes, and the carbon nanotubes are arranged in the same direction or in different directions. The carbon nanotubes in the carbon nanotube rolled film partially overlap each other and are attracted to each other by van der Waals force, and the carbon nanotube structure film has good flexibility and can be bent and folded. In any shape without breaking. And because the carbon nanotubes in the carbon nanotube rolled film are mutually attracted by van der Waals force, and tightly combined, the carbon nanotube rolled film 099122580 Form No. A0101 Page 7 / 36 pages 0992039782-0 201202318 is a self-supporting structure. The carbon nanotubes of the carbon nanotubes of the carbon nanotubes form an angle with the surface of the growth substrate forming the array of carbon nanotubes, wherein /3 is greater than or equal to 0 degrees and less than or equal to 15 degrees, and the angle is cold and The pressure applied to the array of carbon nanotubes is related. The greater the pressure, the smaller the angle. Preferably, the carbon nanotubes in the carbon nanotube rolled film are aligned parallel to the growth substrate. The carbon nanotube rolled film is obtained by rolling a carbon nanotube array, and the carbon nanotubes in the carbon nanotube rolled film have different arrangements depending on the manner of rolling. Specifically, the carbon nanotubes can be arranged in disorder; referring to FIG. 2, when rolling in different directions, the carbon nanotubes are arranged in different directions; when crushed in the same direction, the carbon nanotubes are along a The direction of the orientation is preferred. The length of the carbon nanotubes in the carbon nanotube rolled film is greater than 50 microns. [0019] The area of the carbon nanotube rolled film is substantially the same as the size of the carbon nanotube array. The thickness of the carbon nanotube film is related to the height of the carbon nanotube array and the pressure of the rolling, and may be between 0.5 nm and 100 μm. It can be understood that the larger the height of the carbon nanotube array and the lower the pressure applied, the greater the thickness of the prepared carbon nanotube rolled film; on the contrary, the smaller the height of the carbon nanotube array, the more the applied pressure Large, the smaller the thickness of the prepared carbon nanotube rolled film. There is a gap between adjacent carbon nanotubes in the carbon nanotube film, so that a plurality of sizes ranging from 1 nm to 500 nm are formed in the carbon nanotube film. Clearance or micropores. [0020] The carbon nanotube structure film may be a carbon nanotube film. Referring to Fig. 3, the formed carbon nanotube film is a self-supporting structure composed of a plurality of carbon nanotubes.

And the overall extension direction of the majority of the carbon nanotubes is substantially parallel to the surface of the carbon nanotube film. Further, most of the non-meterite back pipe systems in the carbon nanotube film are connected end to end by van der Waals force. Specifically, in the nanocarbon & film, most of the nanotubes extending in the same direction are each of the carbon nanotubes and the nanotubes adjacent in the extending direction pass the van der Waals end to end. There are a few carbon nanotubes in the film drawn from the n-carbon nanotubes that deviate from the extending direction. These carbon nanotubes do not form an alignment of most of the carbon nanotubes in the carbon nanotube film. Significant impact. The self-supporting n* carbon tube pulls a large area of the new branch building, and only provides shearing force on both sides, which can be suspended on the whole and maintain its own film-like shape. Or @定定) The nano-S S film located between the two bodies when separated by two distances from the two cuts can be suspended to maintain its own membranous state. The self-supporting building is mainly realized by the presence of continuous carbon nanotubes extending through the end of the van der Waals force through the carbon nanotube film. In particular, most of the carbon nanotubes in the nano-stretched film which are substantially oriented in the same direction are not absolutely linear, and may be appropriately bent; or may not be arranged completely in the direction of the extension, and may be appropriately deviated from the extending direction. Therefore, it cannot be ruled out that there may be partial contact between the carbon nanotubes juxtaposed in the majority of the carbon nanotubes extending substantially in the same direction as the nanotubes. [0021] Specifically, the carbon nanotube film comprises a plurality of continuous and aligned carbon nanotubes. The section of the shirt is connected to the rails. Each carbon nanotube segment consists of a plurality of carbon nanotubes that are parallel to each other. The carbon nanotubes have (iv) length, thickness, uniformity and shape 099122580 Form No. A0101 Page 9 of 36 0992039782-0 201202318 Shape. The carbon nanotube film has good light transmittance and the visible light transmittance can reach more than 75%. [0022] When the carbon nanotube structure comprises a multi-layered carbon nanotube film, a preferred angle between the adjacent two layers of carbon nanotube film forming an intersection angle α, α Greater than or equal to 0 degrees and less than or equal to 90 degrees (0° α 90°). Referring to FIG. 4, preferably, in order to increase the strength of the carbon nanotube film, the intersection angle α is approximately 90 degrees, that is, the arrangement direction of the carbon nanotubes in the adjacent two layers of carbon nanotube film. Basically vertical, forming a cross film. a gap between the plurality of carbon nanotube membranes or between adjacent carbon nanotubes in a carbon nanotube membrane, thereby forming a plurality of uniform distributions in the carbon nanotube structure, Arranged randomly, with a size between 1 nm and 500 nm or micropores. [0023] The carbon nanotube structure may include at least one nanocarbon line structure. When the carbon nanotube structure includes a plurality of nanocarbon line structures, the plurality of nanocarbon line structures may be disposed in parallel, wound or woven with each other. The carbon nanotube line includes at least one nanocarbon line. When the nanocarbon line structure comprises a plurality of nanocarbon lines, the individual carbon carbon lines are intertwined or arranged in parallel, and the plurality of nanocarbon lines are combined by van der Waals. [0024] The nano carbon pipeline may be a linear structure formed by processing a carbon nanotube film, and the treatment method of the carbon nanotube film includes a volatile organic solvent infiltration treatment or mechanical torsion treatment. . The volatile organic solvent infiltration treatment may immerse the organic solvent on the surface of the carbon nanotube film by a test tube to infiltrate the entire carbon nanotube film, or the above-mentioned fixed frame formed with the carbon nanotube film may be formed. The whole is immersed in a container containing an organic solvent to infiltrate. The volatile organic solvent is ethanol, decyl alcohol, acetone, dichloro 099122580 Form No. Α0101 Page 10 of 36 0992039782-0 201202318 Ο ❹ [0025] [0026] Ethylene or gas-like implementation of the implementation of ethanol. The tension generated when the hair is produced causes the carbon nanotube film to shrink and conform to the carbon tube. Please refer to Figure 5, and the nanowire of the volatile immersed portion is used to In the carbon pipeline, the π line includes a plurality of carbon nanotubes arranged along the length of the nanotube. With a twist, turn the twisted carbon pipe package = carbon pipe through the van der Waals end-to-end Nei Harbin array. The mechanical torsion treatment can be used in a biaxially preferred orientation, and the force is twisted in opposite directions at both ends of the film. Please refer to FIG. 6 and FIG. 7 'The nano carbon line obtained by the mechanical torsion treatment is a twisted Nylon carbon line'. The twisted nano carbon line includes the nano spiral carbon of the axially helical arrangement of the multi-nano carbon line. Specifically, the twisted nanocarbon pipeline includes a plurality of carbon nanotubes, and the van der Waals force is connected end to end and extends helically along the carbon nanotubes = axial direction. It can be understood that the obtained nanocarbon tube can be obtained by simultaneously or sequentially performing a volatile organic solvent infiltration treatment or a mechanical torsion treatment to obtain a twisted nano carbon line β. Please refer to FIG. 8 and FIG. 9 ' for the nano carbon The tubular film is subjected to mechanical torsion treatment and volatile organic solvent infiltration treatment to obtain a contraction and twist of one of the nano carbon camp wires. After the polymer is infiltrated into the carbon nanotube structure, it is combined with the carbon nanotubes to form the carbon nanotube composite structure. Since the contact angle of the organic solvent to the carbon nanotubes is less than 90 degrees, the polymer dissolved in the organic solvent can be dipped together with the organic solvent in the carbon nanotube structure and the nanocarbon. The tubes are tightly bonded to obtain a carbon nanotube composite structure having excellent mechanical properties. The preparation method of the nano tube breaking composite structure may further include the following: 099122580 Form No. 1010101 Page 11 of 36 0992039782-0 201202318 Step: S30, the polymer impregnated carbon nanotube structure is dried. [0027] In step S30, the organic solvent in the polymer-impregnated carbon nanotube structure is removed, thereby obtaining the organic solvent-free carbon nanotube composite structure. At this time, the mass percentage of the polymer in the carbon nanotube composite structure is approximately between 2.5% and 21.5%. The manner of drying the polymer-infiltrated carbon nanotube structure is not limited, and it may be carried out by natural air drying or by heater drying without merely oxidizing the polymer. [0028] A method for preparing a carbon nanotube composite structure according to a second embodiment of the present invention includes the following steps: [0029] S110, dissolving a polymer monomer in an organic solvent to form a polymer monomer solution, The contact angle of the organic solvent to the carbon nanotubes is less than 90 degrees> [0030] S120, a nanocarbon pipeline structure having a self-supporting structure is impregnated in the polymer monomer solution; and [0031] S130, The polymer monomers in the polymer monomer solution polymerize with each other to form a polymer and are combined with the nanocarbon line structure. [0032] In step S110, the polymer monomer includes any one or combination of acrylonitrile, vinyl alcohol, propylene, styrene, ethylene ethylene or ethylene terephthalate. [0033] The preparation method of the carbon nanotube composite structure provided by the embodiment of the present invention is basically similar to the steps and principles of the preparation method of the carbon nanotube composite structure provided by the first embodiment of the present invention, and the main difference is that the The polymer is infiltrated in the structure of the carbon nanotubes by in-situ polymerization, ie 099122580 Form No. A0101 Page 12 / Total 36 Page 0992039782-0 201202318 完成 Complete the steps through steps S1 20 and S1 30 The function completed by the step S20 in the first embodiment of the invention. Since the solubility of the polymer monomer in the same organic solvent is greater than the solubility of the polymer formed by polymerization of the polymer monomer. Therefore, it is possible to select a polymer having poor solubility in the organic solvent to be composited with the carbon nanotube structure, and only the corresponding polymer monomer has a good solubility in the organic solvent. The polymer can be selected in a wider range, i.e., the carbon nanotube film structure can be impregnated with a polymer that is poorly soluble in the organic solvent. In order to more clearly illustrate the preparation method of the carbon nanotube composite structure of the present invention, the following description will be given by way of specific examples. For the structure of the carbon nanotube film, the wire or other shapes, the treatment method is relatively similar. Therefore, the specific embodiment is described by taking the twisted carbon nanotube line in the carbon nanotube line as an example. [0035] First, polyvinyl alcohol was dissolved in dimethyl hydrazine to prepare a polyvinyl alcohol solution. The degree of polymerization of the polyvinyl alcohol is between 1 750 and 3300. The surface tension of the dimethyl sulfoxide to the carbon nanotubes is approximately 70 degrees, and the surface tension of the dimethyl sulfoxide is approximately 43.45 milli-mines per meter. The mass percentage of the polyvinyl alcohol in the polyvinyl alcohol solution or the concentration of the polyvinyl alcohol solution is approximately between 1% and 9%. Preferably, the mass percentage of the polyvinyl alcohol in the polyvinyl alcohol solution is approximately 5%, so that the polyvinyl alcohol can fill the twisted nano carbon pipeline and can utilize its surface tension to pull The distance between the carbon nanotubes in the near-nano carbon pipeline, thereby reducing the diameter of the twisted nanocarbon pipeline as much as possible, and obtaining a nanocarbon pipeline having a large strength. [0036] Next, the twisted nanocarbon line of FIG. 6 is infiltrated into the alcohol solution of the polyethylene 099122580 Form No. A0101, page 13 / 36 pages 0992039782-0 201202318, so that the polyvinyl alcohol and the The twisted nanocarbon line is infiltrated to form a carbon nanotube composite line as shown in FIGS. 10 and 11. [0037] comparing FIG. 6, FIG. 8 and FIG. 10, and FIG. 7, FIG. 9 and FIG. 11, the carbon nanotube composite line is opposite to the twisted nanocarbon pipeline and the contracted and twisted nanocarbon pipeline, although Both are based on the same carbon nanotube structure, but after treatment, the diameter and density are different. The carbon nanotubes of the carbon nanotube composite wire have a smaller diameter and a higher density, and the gap between the carbon nanotubes is substantially filled with polyvinyl alcohol. Referring to FIG. 12, the diameters of the twisted nanocarbon pipeline of FIG. 6, the contracted and twisted nanocarbon pipeline of FIG. 8, and the nanocarbon tube composite line of FIG. 10 are respectively obtained, and the axial direction resistance is obtained. Tensile strength and Tensile load. It can be seen from the figure that the tensile strength and the tensile load of the carbon nanotubes after composite formation of the carbon nanotube composite wire are significantly improved. Further, please refer to FIG. 13 , which is a tensile-strain comparison diagram of the twisted nanocarbon pipeline of FIG. 6 , the contracted and twisted nano carbon pipeline of FIG. 8 , and the nano carbon nanotube composite wire of FIG. 10 . It can be seen from the figure that after the twisted carbon nanotubes are composited to form a carbon nanotube composite wire, under the same strain, the tensile strength of the carbon nanotube composite wire is greater than that of the twisted nanocarbon. The tensile strength of the pipeline and the contracted and twisted nanocarbon pipeline. Thus, it can be explained that the carbon nanotube composite structure having a large tensile strength, a large tensile load, and a large tensile strength/strain ratio can be obtained by the preparation method of the carbon nanotube structure. [0038] Please refer to FIG. 14 , which is a comparison diagram of tensile strength obtained when the carbon nanotube composite wire is formed in different concentrations of polyvinyl alcohol solution. As can be seen from the figure, the tensile strength of the carbon nanotube composite wire and the polyvinyl alcohol 099122580 Form No. A0101 Page 14 of 36 0992039782-0 201202318 [0040] Ο [0040]
