Polymerization method and product

摘要

Disclosed are uses of polyaniline homopolymer or copolymer prepared by preparing a solution of a polyaniline precursor having at least one aromatic 5 amine group and at least one carboxylic acid group (eg. 2-aminobenzoic acid, 3-aminobenzoic acid or 4-aminobenzoic acid) in a solvent selected from aqueous methanesulfonic acid or aqueous ammonia and optionally one or more additional polyaniline precursors (such as aniline); and oxidatively polymerising the polyaniline precursor or precursors, as an antimicrobial and/or free radical scavenger
