Preparation of N-grafted polyanilines utilizing ring-opening copolymerization of epoxide : Tuning of solubility and optical and electrochemical properties of polyaniline

Abstract

Polyanilines with various degrees of N-grafting have been synthesized by using ring-opening copolymerization of glycidyl phenyl ether (1,2-epoxy-3-phenoxypropane). The obtained polymer has good solubility in common organic solvents. Optical and thermal properties of the N-grafted polyanilines varying with the degree of the N-grafting and length of the graft side chain have been revealed. The polymer received electrochemical oxidation at about 0.40 V versus Ag +/Ag in a CH 3CN solution of 0.10 M LiBF 4.
