Polyaniline dopant conductive polyaniline composition, process for their preparation and

摘要

Provided is a polyaniline dopant which can obtain a conductive polyaniline having a low environmental burden and good processability for polyaniline. A phenol derivative of lignin having a bisarylpropane unit in which an ortho-position and / or a para-position carbon atom is bonded to a C1-position carbon atom of a lignin arylpropane unit with respect to a phenolic hydroxyl group of a phenol compound is used as a polyaniline dopant. Since the phenol derivative of lignin is derived from recycled resources, it is a polyaniline dopant with a low environmental impact.
