ABSTRACT:
The invention provides a polyaniline dopant which has small environmental load and from which an electrically conductive polyaniline having better processability on polyaniline can be obtained. A phenol derivative of lignin having a 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-position of an aryl propane unit of lignin is used as a polyaniline dopant. Since a phenol derivative of lignin is derived from a source that can be recycled, the dopant is a polyaniline dopant having small environmental load.
