Title:
DISPERSANT-CONTAINING CARBON MATERIAL FILM CONTAINING LIGHT-RESPONSIVE DISPERSANT, AND METHOD FOR PRODUCING CARBON MATERIAL FILM USING SAID DISPERSANT-CONTAINING CARBON MATERIAL FILM
Document Type and Number:
WIPO Patent Application WO/2015/016156
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a dispersant-containing carbon material film which enables the easy formation of a carbon material film, such as a CNT, that does not contain a dispersant or contains a dispersant in an extremely small amount; and a method for producing a carbon material film, such as a patterned carbon material film, using the dispersant-containing carbon material film. The dispersant-containing carbon material film is characterized by containing a stilbene-type or azobenzene-type dispersant having light responsiveness and represented by general formula (I) [wherein R1 to R6 independently represent a hydrogen atom or a linear C1-5 or branched C3-6 alkyl group; A represents a carbon atom or a nitrogen atom; X represents an anion; and n represents such a numeral value that nX can have a valency of -2].
