Carbon nanotube dispersion, production method of carbon nanotube structure and carbon nanotube structure

A production method of a carbon nanotube structure comprising:

• preparing a carbon nanotube dispersion, wherein the preparing comprises dispersing or dissolving at least a carbon nanotube compound represented by structural formula A in a dispersion medium;
• and
• supplying the carbon nanotube dispersion onto a surface of a substrate,
• wherein a moiety represented by double lines represents a carbon nanotube;
• R1 represents a hydrogen atom, a substituted or unsubstituted alkyl group having one or two carbon atoms, a substituted or unsubstituted aryl group or a substituted or unsubstituted carbodiimide group;
• R2 represents an unsubstituted alkyl group having from 1 to 4 carbon atoms;
• and
• m and n each independently represents an integer of 1 or more.

A carbon nanotube structure comprising:

• a carbon nanotube compound represented by structural formula B,
• wherein a moiety represented by double lines represents a carbon nanotube;
• X represents OR1 or a crosslinking site, wherein R1 represents a hydrogen atom, a substituted or unsubstituted alkyl group having one or two carbon atom(s), a substituted or unsubstituted aryl group or a substituted or unsubstituted carbodiimide group and the crosslinking site are crosslinked to a carbonyl group in other carbon nanotube compounds represented by structural formula B;
• R2 represents an unsubstituted alkyl group having from 1 to 4 carbon atom(s);
• and
• m and n each independently represents an integer of 1 or more.
