Abstract:
1. An electrically conductive polyaniline composition, comprising: polyaniline, and one or more kinds of lignin derivatives selected from the group consisting of the following lignin derivatives (a) to (e); (a) a phenol derivative of lignin having a 1,1-bis(aryl)propane unit in which a carbon atom on an ortho-position and/or a para-position relative to a phenolic hydroxy group of a phenol compound is bound to a carbon atom on a C1 site of an aryl propane unit of lignin, (b) an acyl derivative having an acyl group in the lignin derivative (a), (c) a carbonyl derivative having a carboxyl group or a group derived from a carboxyl group in the lignin derivative (a), (d) a coumaran derivative in which an introduced phenol compound in the 1,1-bis(aryl)propane unit of the lignin derivative (a) is coumaranized, and (e) a crosslinking derivative having a crosslinking reacting group on an ortho-position and/or a para-position of a phenolic hydroxy group of a lignin derivative of (a).
