Title:
POLYTETRAFLUOROETHYLENE CARBON NANOTUBE COMPOSITE HAVING ELECTRO-CONDUCTIVE PROPERTY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/022528
Kind Code:
A1
Abstract:
The present invention relates to a polytetrafluoroethylene carbon nanotube composite and a method for producing same. The present invention can produce a polytetrafluoroethylene carbon nanotube composite having an electro-conductive property, the electrical resistance of which is indicated by volume resistivity of 1.0E+00Ω.㎝ to 1.0E-02Ω.㎝, the method comprising adding PTFE, CNT and an organic solvent and carrying out a primary agitation, producing an intermediate product by carrying out a second agitation after adding a metal coupling agent, centrifugally separating and removing the organic solvent from the intermediate product, and then drying and pulverizing to obtain a product. The polytetrafluoroethylene carbon nanotube composite can be produced as polymer resin material which can be an alternative to metal due to low electrical resistance while retaining PTFE properties.
