HIGHLY CONDUCTIVE POLYANILINE HAVING EXCELLENT SOLUBILITY AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polyaniline having an excellent solubility in an organic solvent and a polyaniline derivative and to provide a production method for synthesizing a conductive polymer polyaniline exhibiting a high conductivity of ≥500 siemens and a polyaniline derivative.;SOLUTION: An aniline or an aniline derivative is subjected to oxidative polymerization in the presence of a generally useful anionic surfactant having a high hydrophobicity, precipitated, isolated, purified and extracted with an organic solvent to give a polyaniline and a polyaniline derivative that is soluble in an organic solvent and have self-supporting film-forming ability. The polyaniline and the polyaniline derivative that are soluble in an organic solvent and have self-supporting film-forming ability are obtained. The production method for forming the conductive film of polyaniline accordingly exhibiting a high conductivity of ≥500 siemens and having self-supporting film-forming ability and an excellent mechanical strength comprises adding a secondary dopant such as m-cresol, etc., to a polyaniline solution.;COPYRIGHT: (C)2008,JPO&INPIT
