Electrical conductivity and spectroscopic characterization of Blends of poly(2-chloroaniline)/polyaniline P(2ClANI)/PANI copolymer with PVC exposed to gamma-rays

Abstract

Poly(2-chloroaniline)/polyaniline P(2ClANI)/PANI) random copolymer was synthesized in the form of nanoparticles by chemical routes. Incorporation of P(2ClANI) into PANI backbone significantly increased the solubility of copolymer in THF. Thin PVC/P(2ClANI)/PANI blend films were prepared by solvent casting and subsequently exposed to gamma-rays. Conductivity measurements on the irradiated blend films of PVC/P(2ClANI)/PANI showed that conductivity was increased from 10-8S/cm to 10-5S/cm when irradiated to radiation dose of up to 200kGy. The increase in conductivity was also revealed by FTIR and UV-vis spectra. © 2013 Elsevier Ltd.
