That is, the wiring having both elongation and electrical conductivity is preferably conductivity l SZ cm or more, and to have a 1 0% or more stretch. Simply, or disperse the carbon nanotubes and a rubber by using a known technique, the rubber a force - Bon'nanochu part be impregnated using techniques known to the wiring having both elongation and conductivity as in the present invention it is not possible to manufacture a. Conductivity of greater than or 1 S / cm, and a wiring having a 1 0% or more of the stretch is groundbreaking electronic components for the first time realized by the present invention.

Wiring of the present invention can be prepared carbon nanotube rubber composition, carbon nano tube rubber pace Bok, carbon Nanochi Yubu rubber. Wire but it may also contain an ionic liquid as needed. The conductivity of the wiring by Ion liquid increases, stretchability is further improved, the least a part of the wiring Ri is disposed in an elastic material such as rubber, or a and wiring least be such as rubber part it may be covered with elastic material. This is least or insulating part also of the wiring is suitable for adding 弹 sexual function of the rubber to the wiring.

The conductivity of the wiring is more preferable Higher but can not and obtain conductivity surpassing the conductivity of the force one Bon'nanochu Bed itself. Therefore, the force

- conductive 1 0 0 0 S cm of carbon nanotubes is an upper limit of the conductive wires. If the conductivity of the wire is equal to or greater than 1 SZ cm, it can be used as the circuit wiring. If conductivity is 1 0 SZ cm or more, it is suitable for use as a device for interconnection of a large area. If further conductivity 2 0 SZ cm or more, current can flow through the wire is increased, preferably can be driven in a variety of devices.

Elongation of the wiring is preferred over larger, but can not get an extension of you surpass rubber itself. Therefore the upper limit 4 0 0% elongation of the rubber is the upper limit of the elongation of the wire. If stretch ratio of 1 0% or more, can be used wiring as the wiring of the scan Toretsuchiyaburu circuit, it is suitable. If elongation is 25% or more, Ki out bending a wire, Ru suitable der for use as foldable flexible wiring. Further, the wiring if the stretch ratio of 50% or more can be disposed in the free-form surface, Ru suitable der to produce the three-dimensional wiring of various shapes and forms.

Conductive paste of the present invention includes a carbon nanotube rubber paste containing a force one carbon nanotubes and rubber, therefore refers to the conductive paste Bok having both stretchability and conductive properties. Conductive base one be sampled of the present invention is preferably conductivity l S / cm or more, and has a 1 0% or more stretch. Simply, or by dispersing a force one carbon nanotube and the rubber using known techniques, it is impregnated using techniques known to rubber Chikaraichi carbon nanotube, combine elongation and conductivity as in the present invention it is not possible to manufacture a conductive paste Bok. In other words, the conductivity having both elongation and electrical conductivity of greater than or 1 S / cm, and first conductive paste having a 0% or more extension length of the epoch electronic components materials first realized by the present invention is there. Conductive paste of the present invention can be manufacturing carbon nano tube rubber composition, from the force one carbon nanotube rubber paste. Conductive base Ichisu DOO may contain an ionic liquid as needed. The conductivity of the conductive paste Bok by the ionic liquid increases, stretchability is improved.

Furthermore, or a portion also less conductive paste disposed on an elastic material such as rubber, or and the least a part of the conductive paste may be coated with an elastic material such as rubber. This is least or insulating part also of the conductive paste, is suitable for adding a rubber elastic function to the wiring.

The conductivity of the conductive paste is more preferable Higher, but it is impossible to obtain a conductive to surpass the conductivity of the carbon nanotube itself. Thus conductive 1 0 0 OSZ cm of the carbon nanotubes is the upper limit of the conductivity of the conductive paste Bok. If the conductive paste Bok conductivity is 1 SZ cm or more, it is Rukoto using conductive terminal and the wiring for electrically connecting. If conductivity is 1 0 SZ cm or more is preferable in order to electrically connect the wiring and the conductive terminals of the device having a large area. If conductivity is 2 OS / cm or more is found, increasing the current allowed to flow in the electrical connecting portions of the conductive terminals and the wiring, not preferred can drive a variety of devices.

Conductive paste Bok elongation rate is preferable from the larger, but it is impossible to obtain extensibility to surpass the rubber itself. Therefore the upper limit 4 0 0% elongation of the rubber is the upper limit of the elongation of the conductive paste. If stretch ratio of 1 0% or more, the conductive terminals and the wiring of the conductive paste Toosu Toretsuchapuru circuit can be used to electrically connect the, it is suitable. If elongation is 25% or more, the wiring can be bent, and is suitable for use as a bendable flexible wiring. Moreover, if the elongation ratio is 50% or more can and disposed child in free-form surface wiring, stretchable wire according to the invention is suitable for producing three-dimensional wiring of various shapes and forms, conductive pace Bok, known existing substrate, combined with known existing electronic components, an electronic circuit having stretchability can be produced. As used herein, preferably refers to an electronic circuit having a 1 0% or more stretch and extensibility electronics. For example, a configuration of stretchable electronics, provided in known existing substrate, the known existing electronic component, stretch connected to the electrically stretchable wiring using conductive paste Bok and stretchable wiring It can be exemplified circuit.

To realize stretchable electronic circuit of the arrangement is preferably harder than the substrate stretchable wiring. Note that hard herein refers to Young's modulus is large. In general, it is known existing substrate, an electronic component known existing is hard, no stretch. Further, there is a problem that electrical characteristics are changed when distorted existing electronic components.

By the electronic circuitry according to the present invention described above, when the electronic circuit is subject to distortion, softer elastic wire strain, rigid substrate is not distorted. As a result, the electrical characteristics of the electronic components on the substrate does not change. Furthermore, during the stretch lines and electronic components on the board, by connecting with a stretchable conductive paste Ya stretchable wire having, electronic components can be stretchable wiring electrically connected. Conductive paste Ya elastic wires stretching and distortion by absorption, without causing strain to the electronic component, does not change the electrical characteristics of the electronic component. Such electronic circuit arrangement has a whole circuit is elastic, and also by stretching, it has a feature that a small change in electrical characteristics of the circuit. Such stretchable electronics is for the first time been realized by the present invention.

Useful substrate to the electronic circuit is not particularly limited, the electronic component harder than setting takes it be stretchable wiring, also can use any known substrate, not influenced shape, material, thickness . Various metals, ceramics, silicon, planar to a resin or the like material, curved, can be exemplified frame Kishiburu substrate.

The electronic component of the present invention is not particularly limited, can be electrically connected by a conductive paste or a stretchable wire can Rukoto to be used any known electronic components. CMOS electronics, transistors, integrated circuits, organic transistors, light-emitting elements, Akuchiyue Isseki, memory, sensors, Koi Le, capacitors, resistors, and can be exemplified combinations thereof.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Carbon nanotubes rubber composition, carbon nanotube rubber, it forces one carbon nanotube paste, wire, as the carbon nanotubes contained in the conductive paste, as appropriate any of single-walled carbon nanotubes (SWNT) and multi-walled carbon nanotubes (MWNT) also it can be used. In order to realize has high conductivity, and the carbon nanotube rubber composition having a high elongation, it carbon nano tube is long, purity is high, and high specific surface area is preferable. Therefore, generally lower specific surface area, than even a short multi-walled carbon nanotubes length, high specific surface area, is long monolayer force one carbon nanotube length is more preferable.

High conductivity, in order to obtain a high elongation rate, the carbon nanotubes' unless long desirably possible. This is because when the carbon nano Chupu rubber carbon nanotube network in a composition (stitch structure) is composed of long carbon nanotubes, net even more if the electricity is passing to route many can be formed, and was extended network There is because less likely to be more destruction. Highly conductive, there is no upper limit on the length of the carbon nanotubes in obtaining a high elongation, producing generally long carbon nanotubes becomes more distributed is low carbon nano Chu Bugomu composition becomes difficult. Especially 1 or 1 0 cm or less of the length of the carbon nanotube has good dispersibility length, of high purity is easily obtained, preferable for obtaining high conductivity, a high elongation. High conductivity in the following carbon nanotube 1 m length, it is difficult to form a network for realizing a high elongation. Is 1 0 cm or more carbon nanotubes length has poor dispersibility, and is easily broken during dispersion treatment.

While having the carbon nanotube diameter of nanoscale, it is due to the long very elongated nanomaterials, it is very difficult to measure the length of one single length. For the present invention, Yibin, Ion liquid

, The solvent, the car Pont nanotube dispersion containing polymer one rubber or rubber diluted thinly with an organic solvent or the like was dropped on the substrate, scanning atomic force microscope by the length of the carbon nanotubes II guess one by one rather, it can be evaluated by measuring the length of the bundle. The length of the carbon nanotubes length of the force one carbon nanotube bundles, measured by a scanning atomic force microscope and the structure there is a correlation, the bundle composed of long carbon nanotubes becomes longer. Especially carbon nanotubes bundle length 1 0 cm or less in length 1 m or more preferable for obtaining high conductivity, a high elongation.

Further, as the carbon nanotubes, carbon nanotubes oriented vertically aligned from the substrate using the method described in Japanese Patent Application No. 2 0 0 6- 5 2 7 8 9 4 (WO 2 0 0 6/0 1 1 6 5 5 corresponding) when used in stripping the aggregate from the growth substrate, Ru can be the height of the vertically aligned carbon nanotubes oriented aggregate of carbon nanotubes with lengths. That carbon Nanochi Yubu oriented collection of height 1 0 cm or less in length 1 m or more preferable for obtaining high conductivity, a high elongation. High conductivity, in order to obtain a high elongation, it is desirable as far as possible the carbon nanotubes of high purity. The term purity and is-carbon purity, indicates what percentage of the mass of the carbon nanotube is composed of carbon. Highly conductive, there is no upper limit to the purity of in obtaining a high elongation, for convenience of manufacture, it is difficult to obtain a 9 9.9 9 9 9% or more of the force one carbon nanotube. When the carbon purity contain impurities such as metal is less than 90%, metal impurities are agglomerated during the manufacturing process, since the carbon nanotube rubber composition becomes brittle, difficult to obtain a high conductivity, high elongation to become. From these points, the purity of the force one carbon nanotube is preferably 90% or more.

The purity of the carbon nanotubes, obtained from elemental analysis using fluorescence X-rays. Was elemental analysis of single-walled carbon nanotubes used in Example 1 below by the fluorescent X-ray, carbon 9 9.9 8%, is iron 0.0 1 3%, other elements were not measured .

Further, highly conductive, in order to obtain a high elongation is preferably as far as high specific surface area capable of carbon nanotubes. This carbon nanotubes with high specific surface area, the surface is large, because the easily interaction interface is increased with an ionic liquid and rubber. Moreover, the force one carbon nanotube of high specific surface area, the carbon nanotube other than carbon impurities, less content of impurities other than carbon, such as a metal, is preferred for the reasons described above. Single-walled carbon nanotubes having a specific surface area is less than 6 0 0 m 2 / g is several tens of percent of the weight of impurities or carbon impurities, such as metal (about 4 0%) comprise and, monolayer force one Ponna Bruno tube originally it is not possible to express the function, it is not suitable.

The specific surface area of the single-walled carbon nanotubes is generally preferred the greater the theoretically has an upper limit, and those unopened at 1 3 0 0 m about 2 Z g, obtained by opening 2 6 0 is 0 m 2 / g or so.

The specific surface area of ​​the single-walled carbon nanotubes can be determined by measuring the adsorption-desorption isotherm at 7 7 K of liquid nitrogen. As an example, the single-walled aligned CNT aggregate 3 0 mg, can be obtained from the adsorption-desorption isothermal curve was measured using the BELS ORP-MINI (Co. Japan Bell) (adsorption equilibrium time was 6 0 0 seconds ). Used in the present invention, Brunauer from adsorption and desorption isothermal curve of the single-walled carbon nanotubes, EmmeU, was measured specific surface area Teller method was 1 1 0 0m 2 Z g. Incidentally, by changing the aperture processing temperature from 3 5 0 ° C to 6 0 0 ° C, 1 0 0 Om 2 / g~ 2 3 0 0 m 2 specific surface area of the monolayer force one carbon nanotube in a range of Zg It can be changed, or mow the single-walled carbon nanotubes are preferred to achieve a carbon nanotube rubber composition of the present invention to obtain Bei serves as a high conductivity and high elongation.

Carbon nanotubes rubber composition of the present invention, the carbon nano-Ju one Bugomu force one carbon nanotube paste, wire, useful ionic liquids conductive base Ichisu preparative is not particularly limited, carbon Nanochi Yu over Bed and high affinity, gel-like and made things good Mashiku upon distributed processing, for example, 1-Echiru 3- methylimidazolium Riu arm tetra Furuoroporeto (EM IBF 4), 1- Echiru - 3 Mechiruimi to Dazoriumu Kisa full O b phosphate (EM IPF 6), 1-Echiru 3- methylimidazolium Riu arm bis (triflate Ruo b methyl scan Ruhoniru) imide (EM ITFSI), 1 one-butyl - 3-Mechirui Midazoriumu tetrafluoropropoxy O Lobo, single Bok (BM IBF 4), to 1 over Bed Chiru 3- methylimidazolium Riu arm hexa full O b phosphate (BIPF 6), 1 one Puchiru 3- Mechirui Midazoriumu bis (triflate Ruo b methylsulfonyl) imide (BM ITFSI) mentioned can Rukoto.

. Could you to produce a carbon nanotube composition having both the case where the content is less than 4 0% by weight more than 0 wt% elongation and conductivity of the ionic liquid.

Carbon nanotubes rubber composition of carbon nano Ju Pugomu of the present invention, the carbon nanotube paste lines, conductive base - Useful rubber scan Bok, not particularly limited, Ri broadly Elastic Bokuma - may be a, in particular the elastic material or elastic rubber to an organic polymer as a main Ingredients such as natural rubber or synthetic rubber is preferred. For example, fluorine rubber (e.g., manufactured by Daikin Industries, Ltd., D aie 1 - G 8 0 1 D aie

1 - G 9 1 2), natural rubber, propylene rubber butadiene rubber, I Sopurengomu, styrene-butadiene rubber click a port Purenaku 'J port rubber, nitrile butadiene rubber, butyl rubber ethylene propylene rubber, urethane rubber, silicone rubber, click mouth styrenated Poryechire Ngomu, polyethylene chlorinated rubber, Akurirugomu, Epikuro □ human de V Ngomu, be used any of rubber such as polysulfide rubber away at. Among these, from giving sufficient elasticity to the handling it is easy 1 is the composition, and does not inhibit the desirable properties viewpoint, fluorine rubber and silicone Ngomu preferably

As the organic solvent, such rubber rather by Melle in that dissolves and may be selected in due connexion appropriate rubber used. Specifically, Toruen xylene, § Se h emissions, carbon tetrachloride or the like can be used, in particular preferred a 4-methyl-2 pen evening non because many rubber containing hydrofluoric rubber and shea U Kongomu is soluble It can be used in actual

Force Pont nanotube rubber composition of the present invention, the carbon nano-Chu Bugomu, carbon nanotube paste, wire, Oite the conductive paste, high electrical conductivity and elastic stretchability as the carbon nanotubes are uniformly dispersed in the composition Become. That is, in order to achieve an article of the present invention having both high conductivity and high elongation rate, long, high purity, high specific surface area carbon nanotube, its function without I a loss, how in the rubber either by uniform dispersion is important. In general, the carbon nanotubes have a low material highly soluble, affinity with the rubber material is low, it does not disperse in the rubber. Therefore, carbon nano tubes are uniformly dispersed, combines high conductivity and high elongation Therefore, realization of the article of the present invention was extremely difficult. The present inventors have conducted extensive devised, in order to increase the dispersibility of the carbon nanotubes and the rubber was found to be preferable to use an ionic liquid. JP 2 0 0 5 1 7 6 4 2 8 No. as described in Japanese force - carbon nanotube and an ionic liquid have high affinity, distributed processing forces one Ponna entry tube in the ionic liquid by it becomes gelatinous. This detailed aircraft structure of carbon nanotubes ionic liquid gel forms is not known at present, the ionic liquid is adsorbed on one by one carbon nanotube, the van der Waals forces that wore shoes to each other carbon nanotubes weakening and if Kangaeraru. As a result, carbon nanotubes usually easily bundled is dispersed in ionic liquids to form a gel composition. So to speak, an ionic liquid as a dispersant for the force one carbon nanotube is believed to function.

In the present invention, the inventors, using a rubber miscible with the ionic liquid, found that can uniformly disperse the rubber in the carbon nanotube ionic liquid gel, highly conductive invention, high It was achieved force one carbon nanotube rubber composition having both extension length ratio. By mixing sum, although detailed aircraft structure of carbon nanotubes rubber composition is formed is not known at this time, I on liquid adsorbed to the carbon nanotubes, by mixing has a rubber affinity, the carbon nano-tube it possible to blend in the rubber, that is normally distributed min in the rubber are difficult carbon nanotubes are uniformly dispersed in the rubber and considered Erareru.

Here, the miscible refers ionic liquids, polymers of rubber or rubber, the interleaf cormorants properties mixed to the extent that the dispersion solution is not phase separate containing an organic solvent as needed. No upper limit to the degree of preferred miscible, substantially above Symbol force one carbon nanotube, mixes the rubber and the ionic liquid and the organic solvent as needed, carbon nanotubes are uniformly dispersed in the rubber, the final to highly conductive, high carbon nano tube rubber composition having both elongation rate may be a degree that can be produced, usually the ionic liquid and the rubber or rubber polymer one, number dispersion containing an organic solvent as required hour, more preferably is suitable as long as that does not separate phase for several days.

Ionic liquid and rubber or rubber polymer, that an organic solvent compatibility, if necessary, good preferable in order to achieve better miscibility, dispersibility. Here, the compatibility, two or multiple types of substances mutually having affinity refers to a property of forming a solution or admixture.

Thus, with the ionic liquid, miscible, compatible, with polymer Gomuyago beam and producing carbon nanotube composition, it forces one carbon nanotubes are uniformly dispersed in the rubber. That is, the force one carbon nanotube, ionic liquid rubber is uniformly dispersed, carbon nanotube rubber composition of the present invention to incorporate, carbon nano Chu Bugomu force one carbon nanotube paste, wire, the production of the conductive paste , jet Tomiru the mixing and dispersing of the components, ball mill, may be used an ultrasonic dispersing machine, it is preferable to use a jet Tomiru from the viewpoint of uniformly dispersing the composition of carbon nanotubes.

For example, E as omitted molding of S 3, it may be molded processing after step S 4. If necessary, in a suitable step may be added as appropriate crosslinking agent or a crosslinking initiator and the like. Further, steps S l for method of manufacturing the carbon nanotube rubber composition, dispersion techniques used in step S 2 is not limited to the above, the force one carbon nanotube, ionic liquid, how rubber can be uniformly dispersed if Ru can be used as appropriate dispersion techniques known carbon nanotubes.

Example 1

To specific examples below, the carbon nano-Ju Bugomu composition according to the present invention, the force one Pont nanotube rubber paste, carbon nano tube rubber, wire, that describes in more detail the conductive paste.

As the carbon nanotube, No. 2 0 0 9 - 0 0 1 5 8 6, JP Application 2 0 0 6 - grown oriented perpendicularly from the substrate using the method described in 5 2 7 8 9 4, carbon nanotubes stripping the oriented current age body from the growth substrate, using a powdery single-walled carbon nanotubes (hereinafter SWN T). Carbon nanotubes, Density: 0. 0 3 g / cm 3 , BET- specific surface area: 1 2 0 0 m 2 / g, the average outer diameter: 2. 5 nm, half width 2 nm, a carbon purity 9 9.9% , orientation coefficient 0.8 Herman, having a length 3 0 0 m or more 8 0 0 the following properties.

Organic solvent 4-methyl-2 - Pen evening added non (typical amount 2 0 ml) to SW NT (typically amount 3 0 mg) and the ionic liquid BM ITFSI (typically amount 6 0 mg), scan evening with an error, the rotational speed conditions of more than 7 0 0 rpm, and stirred for 1 6 hours at room temperature, placed in the resulting mixture Jefferies Tsu Tomiru disperser (NANO-JET PAL, JN 1 0, J OKOH Ltd.), 6 0 MP to jet in a, by uniformly dispersing carbon nanotubes in an organic solvent to obtain a carbon nanotube ionic liquid gel (step S 1).

Next, the carbon nanotube ionic liquid gel in an organic solvent 4 - methyl one 2-pentanone (typically amount 8 0 m〗) and fluororubber (manufactured by Daikin Industries, Ltd. D aie having miscibility, compatibility with the ionic liquid 1 - G 9 1 2) (the typical amount 5 0- 1 5 0 O mg) was added, using a scan evening one la foremost, under the conditions of about 3 0 0 r pm, and stirred for 1 6 hours at room temperature to obtain a carbon nanotube rubber paste as shown in FIG. 3 (step S 2).

The carbon nanotube rubber dispersed gel by drying for 12 hours at room temperature to give a force one carbon nanotube rubber shown in FIG. 8 (S 4 as E). The composition of the carbon nanotube rubber S WN T 2 1 wt%, BMITFSI 4 3 wt%, Ri G 9 1 2 3 6 wt% der conductivity showed 7 3 SZ cm.

Alternatively, obtained in step S 2, it dried for 6 hours a carbon nanotube rubber base one be sampled at room temperature, 4 one methyl - 2-pen evening by evaporation a portion of the non, after adjusting the viscosity, silicone Elastica Tomah first substrate (P DM S, 3 1 &]:. & (1 1 8 4, 00 chromatography (0] "] 1 11 stock company) was printed in the desired pattern on (step S 3) here, subscriptions to adjust the order of 1 P the as the viscosity in the case of using over screen printing or stamping printing, when the dispenser or inkjet printing is preferably between 1 0 m P as about the viscosity.

The PDMS carbon nanotube rubber pace bets printed on the substrate by further drying, the width 1 0 0 m P DM S wiring composed of carbon nanotubes rubber substrate which is pattern in the line width of 9 obtained (step S 4). Figure 1 0 is a diagram bent wire made of such P DM S force one Ponna Bruno tube rubber substrate. Wires not broken line, it can be seen that the lines composed of carbon nanotubes rubber have elongation properties. Such force one carbon nanotube rubber is an example of a stretchable wire of the present invention. Figure 1 1 is an image of a scanning electron microscope of an enlarged portion of the pattern has been force one Pon'nanochu Bugomu in FIG. Rubber miscibility with I O emissions liquids, in order to have a compatible rubber carbon nanotubes (white structure) in (black structure) are uniformly dispersed, one Mari rubber and an ionic liquid and carbon and the child that nanotubes are mixed can be seen. 9, 1 0, 1 0 stretch lines by the carbon nanotube rubber, 1 1 is a substrate.

In Shin compression resistance wire made of carbon nanotubes rubber obtained as described above, the carbon nanotube rubber obtained by changing the S WNT content 1.4 wt% to 1 5.8 wt%, electrical conductivity, elongation It was measured. Mass ratio of SWNT and BM ITFSI was 1: 2. S WNT content of Despite greatly varied, exhibit high conductivity and extensibility ratio was possible to manufacture a good Ru wiring name of carbon nanotube rubber.

The relationship between the SWNT content and electrical conductivity and elongation at this time is shown in FIG. 1 2 A and B. As can be seen from Figure 1 2 A, conductivity and elongation, to the SWNT content, is inversely related. Wiring composed of carbon nanotubes rubber obtained as described above is 1 and the conductivity of the S / cm to 1 0 2 SZ cm, to exhibit elongation from 2 9% to 1 2 9% confirmed It was.

This result, by controlling the content of the force one carbon nanotube shows a carbon nanotube composition, carbon nanotube rubber, conductive wire, that it is possible to continuously control the elongation. In the manufacturing process method of this embodiment, the content of the force one carbon nanotubes 1. Between 4 wt% 1 5. up to 8% by weight is suitable to achieve high conductivity, a high elongation It is shown that.

Further, from FIG. 1 2 B, wiring composed of the carbon nanotubes rubber, also without conductivity changes by stretching, it can be seen that is suitable as a stretchable wire.

In the above process, the fluorine rubber in order to increase the expansion ratio further - instead of (D aiel G 9 1 2), silicone rubber (Dauko-learning Co. S y 1 gardl 8 4 or SH 9 5 5 5) used, the carbon nanotube composition, forces one carbon nanotube rubber was prepared wires were evaluated, expansion ratio was found to be more than 1 50%. This result indicates that the high conductivity of a variety of rubber, forces one carbon nanotube composition with high elongation, a carbon nanotube rubber, wiring can be manufactured.

And the ionic liquid necessary to produce the carbon nanotube rubber composition of the present invention were tested for miscibility of the rubber. Is an ionic liquid, BMITFSI, EMIBF 4 BMIBF 4, it is as a rubber, with a G 8 0 1, G 9 1 2, Kyner. Mix each of the rubber polymer 3 0 O mg and each of the ionic liquids 3 0 O mg 2-methylcarbamoyl Lou 2 Pen evening non of 1 O ml, stirring the resulting solution with 12 hours stirrer one room did. Then, leaving the dispersion for 3 days, and then observed. As shown in FIG. 1 3, of the nine types of combinations, the phase separation of the ionic liquid and the rubber polymer was observed by five. This combination of five kinds of the ionic liquid and the rubber polymer, the carbon nanotube composition with has a high conductivity, and high elongation can not be produced carbon nanotubes rubber, wires, those produced or was weak, It could not be molding into a film shape. Against it, the ionic liquid and the rubber has failed to to phase separation miscible, 4 in the combination of the kind of ionic liquid and the rubber polymer, having a high conductivity, and the carbon nanotube composition with high elongation, carbon nanotubes rubber was possible to manufacture a wiring. This result indicates that the high conductivity of a combination of different rubber and the ionic liquid, the carbon nanotube composition with high elongation, carbon 5 nanotubes rubber, wiring can be manufactured. Furthermore, having a high conductivity, and a carbon nanotube composition with high elongation, a carbon nanotube rubber, for the realization of the wiring, miscible I O emissions liquids and rubber indicates a important there.

Carbon nanotubes rubber composition according to the above production method, by changing the carbon nanotube rubber, carbon nanotubes rubber paste, S WNT stretch wiring, BMITFSI, the composition ratio of G 9 1 2, conductivity was evaluated elongation . The content ratio of S WN T and BMITFSI 1: 2 fixed, the amount of 09 1 2 1 0 0 1118, changing the S WN T 1 4 ranging from mass% 1 5. 8% by weight. strain one stress characteristics when the 1 7 electrical characteristics in Figure 1 4. Removing the ionic liquid, 1 5 the distortion tentative force characteristic when changing the S WN T 1. Range 5 wt% of 2 3% by weight, showing the electrical characteristics in FIG 7. Figure strain one stress characteristics when S WN T and G 9 1 2 amounts respectively to 3 O mg and 5 0 O mg, the content of BM ITFSI varied from 0-3 1.2 wt% It is shown in 1 6.

Comparing the case with and without ionic liquid (Fig. 1 4) (Fig. 1 5), it can be seen that the ionic liquid has a significant effect in improving the extensibility. 1 4, 1 5, comprising an ionic liquid, regardless of the not included in S WN T 1.

Also it shows that having a significant effect on improving Ion liquid is conductivity.

Example 2

Further according to the present invention, the carbon nanotube rubber composition, carbon nanotube rubber pace Bok, carbon nanotubes rubber, is described below another production method of the wiring.

As the carbon nanotube, No. 2 0 0 9 - were grown vertically aligned from the substrate using the method described in 0 0 1 5 8 6, JP Application 2 0 0 6 one 5 2 7 8 9 4, carbon nanotubes peeling the aligned aggregate from the growth substrate, using a powdery single-walled carbon nanotubes (hereinafter SWN T). Force one carbon nanotube, density: 0. 0 3 g / cm 3 , BET- specific surface area: 1 2 0 0 m 2 Z g, the average outer diameter: 2. 5 nm, half width 2 nm, a carbon purity 9 9. 9% orientation coefficient Herman 0.8, having a length 3 0 0 or 8 0 0 m following characteristics.

Typically, SWNT a (5 0 mg) was mixed with 5 O mg of ionic liquid (BITFSI), multiplied resulting suspension in automatic grinding system for 1 hour, the black paste like force one Bon'nanochu Buion liquid gel was obtained (step S 1).

This gel 1 0 O mg, in turn, 2 - methyl - 2 - and pentanone 8 ml, fluorine rubber a is Kisafuruoropuro Pirenkoporima one to vinylidene fluoride one (manufactured by Daikin Industries, Ltd. D aie 1 - G 8 0 1, just below was added G 8 0 1 hereinafter) 1 0 0 1118, the resulting mixture was stirred for 1 hour at 2 5 ° C, 3 0 and ultra sound wave treatment for 1 hour at in (SMT Co. UH _ 5 0). 8 0 ° inflated forces one carbon nanotube rubber paste again stirred Te Watatsu to 1 hour at C is obtained (step S 2).

This force one carbon nanotube rubber pace Bok, poured on a glass plate by drop-casting ring (Step S 3), was 2 over 4 hours air drying, and removal of the organic solvent, as shown in FIG. 1, film-like carbon nanotubes rubber was obtained (step S 4).

It was recovered liquid 99% of the ions used for retrieving ionic liquids using Soxhlet method (step S 5). The conductive carbon nanotube rubber not containing the produced ionic liquid body is 1 0 SZ cm, were 1 0% or more stretch.

The film-shaped carbon nanotube rubber, but with flexibility and elongation properties, shrinkage is not so large. To improve the extensibility and shrinkability, after the formation of the net-like structure as shown in FIG. 2 Ficoll Lum-shaped carbon nanotube rubber machined using a numerically controlled (NC) punching system, dimethylsiloxane covered with silicone rubber based (P DM S, Dauko-learning Co. S y 1 gard 1 8 4 or SH 9 5 5 5). P DM S coated with film-like carbon nanotube rubber obtained are shown in Figure 4.

P DM S coated with film-like carbon nanotube rubber for combine elongation and conductivity, it is useful as stretch wires. Suitable reticulated, linear, molded processed into a wire shape, carbon nanotubes rubber-like coated with P DM S film is an example of a stretchable wire of the present invention.

The obtained film-shaped carbon nanotube rubber and PDMS coating film-shaped carbon nano Ju one Bugomu than the examined pull Shin bridge, the electrical and mechanical properties. 1 8 shows a Kinoshirube conductivity that is extended. For comparison, also it shows the commercial conductive rubber containing carbon particles (Kinugawagomukogyo). While Shin length rate commercial conductive rubber exceeds 1 5 0%, the conductivity was as low as 0. 1 S / cm (curve 3). The conductivity is insufficient for use as a wiring of an electronic circuit. In contrast, film-shaped carbon nanotube rubber, shows a very large conductivity of 5 7 SZ cm, stretch ratio of at the time of 3 8% or less significant change in conductivity and mechanical degradation was observed ( curve 1). Furthermore, P DM S coating film-shaped carbon nanotube rubber, 5 7 S / cm showed great conductivity that, 1 3 be extended up to 4%, the conductivity was not reduced little by (curve 2> . 1 3 4% © conductivity even under extended showed 6 SZ cm. as a result, the force one produced according to the present embodiment carbon nanotubes rubber and P DM S coated fill beam-like carbon nanotube rubber elongation and it indicates that combines sex and conductivity.

Carbon nanotubes rubber composition of this example was examined carbon nano Ju Bugomu force one carbon nanotube rubber base Ichisu DOO, and the ionic liquid necessary to produce the elastic wire, the miscibility of the rubber. As the rubber polymer, the composition ratio 0. 7 8: 0. 2 2 (G 8 0 1) and 0.8 8: was 0. 1 2 (A rkema Co. KYNAR- FLEX, referred to hereinafter simply KYNAR) vinylidene fluoride - to Kisafuruo port propylene copolymer, with respect to the ionic liquid, in addition to BMITFSI, were used BMIPF 6 and BMIBF 4.

Mutually miscible, a combination of Gomuporima one and Ion liquid having compatibility, when using G 8 0 1 and BM ITFSI, carbon nanotubes rubber of the resulting films shaped, very smooth, flat, it is uniform, and combines the extension and conductivity as described above.

Conversely, miscibility, in combination with the combination and KYNAR and BM ITFSI the G 8 0 1 and BMIBF 4 having no compatibility, film-shaped carbon nanotube rubber having both good stretch properties and conductivity It could not be produced. For example, a hard resin KYNAR is not miscible with BMITFSI, film-like force one carbon nanotube rubber obtained by this combination was readily or deformation wrinkling. , The mixed sum of the ionic liquid and rubber for this result has a high conductivity, and the carbon nanotube composition with high elongation, force one carbon nanotube rubber, forces one Pon'nanochu Bugomupesu DOO, wiring realization sex, compatibility indicates that it is important.

Force one carbon nanotube rubber composition by the method of the present embodiment, the force one carbon nanotube rubber, carbon nanotubes rubber paste, S WNT stretch lines, BMITFSI, by changing the G 8 0 1 composition ratio, conductivity, elongation rate, was evaluated the hardness.

First, SWNT and G 8 0 1 amounts were to 5 0 mg and 1 0 0 mg respectively, were changes in the range of 1 2-4 7 wt% content of BMITFSI. When the content of BM ITFSI 4 greater than 0 wt%, off Ilm shaped carbon nanotube rubber could not be produced. When this fluorine-chromatic weight is less than 1 0% by weight, carbon nanotubes rubber becomes brittle, and the conductivity was small. As shown in FIG. 1 9, the content of BMITFSI cases 1 0 wt% or more 4 0 wt% or less, it was possible to produce carbon nanotubes rubber comprising serves elongation and conductivity. Film-shaped carbon nanotube rubber produced Te this good Unishi, in addition to excellent electrical properties, shows excellent mechanical properties and a very smooth surface, it could be suitably used in the stretch lines. Maximum conductivity of 5 7 S / cm was obtained when the content of S WNT and BMITFSI is 2 0 wt% both. Thus the large conductivity is realized is because also contain SWN T 2 0 wt%, without flexibility or softness is sacrificed, good carbon nanotube rubber could be produced . This ionic liquid and rubber miscibility, has a compatibility, because the carbon nanotubes are uniformly dispersed in the rubber. That is, the carbon nanotube, ionic liquid, rubber uniformly dispersed, mixed and was, because carbon nanotubes rubber could be produced.

As a result, the ionic liquid shows preferable for good carbon nanotube rubber manufacture and have a remarkable Shii effect of improving elongation and conductivity. Further, the carbon nanotube rubber composition having both elongation and conductivity, carbon nano Ju one Bugomu force one carbon nanotube rubber paste, the content of ionic liquids for the elastic wires 1 0 wt% or more 4 0 wt% or less indicates that the preferred.

Then, S the WNT and content ratio of BM ITFSI 1: fixed to 1, the amount of G 8 0 1 to 1 0 O mg, was changed in the range of 4 5 wt% of S WNT from 1 wt%. When the content of SWN T is less than 1 0% by weight, full Ilm shaped carbon nanotube rubber could not be produced. When the content of SWNT is 3 0 mass% or more, the force one carbon nanotube rubber becomes brittle, and the conductivity was small. As shown in FIG. 2 0, the content of S WN T cases 1 0 wt% to 3 0% by mass or less, it was possible to produce carbon nanotubes rubber comprising serves elongation and conductivity. Film-shaped carbon nanotube rubber produced Te this good Unishi, in addition to excellent electrical properties, shows excellent mechanical properties and a very smooth surface, it could be suitably used in the stretch lines. When the content of S WNT is 1 6 mass%, conductivity and 5 3 S cm large Natsuta. This result, in this embodiment, the carbon nano-Chu Bugomu composition having both elongation and conductivity, carbon nanotubes rubber, forces one carbon nanotube Gomupesu preparative content of SWNT in order stretch wire 1 0 wt% indicates that the preferred 3 0 mass% or more.

Then, the amount of G 8 0 1 to 1 0 O mg, 1 the content ratio of S WN T and BMITFSI: 2 to 2: to 1 is changed, and S WN T and BM

The content of 1 TFSI was changed from 3 0 O mg. The Conductivity 2 1, the content ratio of S WNT and BM ITFSI showing critical elongation in FIG 2 (elongation limit the object breaks) is 1: 2 to 1: when in the second range, elongation We were able to manufacture a carbon nanotube rubber having both gender and conductivity. This result, in this embodiment, the carbon nanotube rubber composition having both elongation and conductivity, carbon nanotubes rubber, carbon nanotubes rubber paste, the content ratio of SWNT and BMITFSI in order stretch wires 1: 2 to 2: it indicates that 1 is preferred.

Using carbon nanotubes rubber paste containing G 8 0 1 obtained in step S 2 of Example 2, by the this cross-linking the polymer Matrigel box consisting of G 8 0 1, conductive which is based on S WN T to produce a gender paste. Ie, the G 8 0 1 containing carbon nanotubes rubber paste, having the following structure, peroxide crosslinking initiator (NO F Co. per hexane -

2 5 B) 1. added 3 mg and the crosslinking agent (TA IC) 4 mg, and air dried The resulting mixture was stirred for 1 hour at 80 °, including fluorinated polymer partially crosslinked conductive base Ichisu preparative shown in FIG. 3 were obtained. The conductive paste includes a. 5 to 1 0 SZ cm and Re Cormorant large conductivity showed greater adhesion capability. Therefore, the conductive paste is suitable for applications such as Con Yuku Topa' de Ya wire, suitable to electrically connect the stretchable wire by the electronic component and the present invention of organic transistors evening etc. provided on the substrate it is.
