METHOD FOR PRODUCING THREAD-SHAPED CARBON NANO STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a thread-shaped carbon nano structure, which can produce the thread-shaped carbon nano structure which has a structure that has not existed in the past, has high conductivity, can be used under a high-temperature environment, and further has characteristics different from a conventional sheet containing a carbon nano structure.

SOLUTION: The method for producing the thread-shaped carbon nano structure comprises in this order: a first step of mixing at least a dispersion liquid of the carbon nano structure with a fiber to produce a mixed dispersion liquid; a second step of producing a belt-shaped sheet containing the carbon nano structure by using the mixed dispersion liquid; a third step of twisting the belt-shaped sheet containing the carbon nano structure to produce yarn containing the carbon nano structure; and a forth step of producing the thread-shaped carbon nano structure that mainly contains the carbon nano structure by heating the yarn containing the carbon nano structure to carbonize or remove the fiber therein.
