Abstract: The effect of γ-ray irradiation on the emeraldine (EM) base form of polyaniline was investigated. The processes of γ-ray, UV, and thermally-induced graft copolymerization of EM base with acrylic acid (AAc) in a number of solvents and co-solvents were compared in an attempt to prepare a water-soluble EM through N-acylation. The presence of N-acylation was investigated by thermogravimetric (TG) analysis, Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). In all cases, the graft concentration and the resulting surface conductivity were shown to be a function of the monomer concentration. The thermostability and weight loss behavior of the graft-copolymerized EM included those that were characteristic of the EM base, the AAc polymer and the amide polymer. Some of the graft-modified EM base samples exhibited good water solubility. In particular, the γ-ray-induced graft copolymerization of EM with AAc in N-methyl-2-pyrrolidimone(NMP)/water co-solvent readily gave rise to a water-soluble, self-protonated and semi-conductive EM, which could be cast into free-standing films from an aqueous solution.
