Electrical Conductivity and Antibacterial Studies on Chemically Synthesized Poly (2-Methyl Aniline-co-2-Chloro Aniline)-Blend-Polyurethane

Abstract

Abstract

Electrically conducting copolymer blend, poly (2-methyl aniline-co-2-chloro aniline)-blend-polyurethane has been synthesized chemically by oxidative polymerization technique using 0.3 M ammonium persulphate (APS) as oxidant, 0.1 M of the anionic surfactant, sodium lauryl sulphate and 1 M HCl as dopant. The formation of the copolymer blend has been confirmed by comparison with the spectral data obtained for the copolymer which was synthesized under the same conditions and characterized. The copolymer blend was characterized by FTIR, UV-visible, XRD and 1H NMR spectroscopy. The synthesized polymer blend was crystalline in nature. The thermal stability was analyzed by TGA/DTA analysis and it showed a four step weight loss which is an evidence to account for the incorporation of the anionic surfactant moiety as another dopant. The electrical conductivity measured was 2.723x10^-5 Sm^-1, in the semiconducting range and the antibacterial activity of the copolymer blend has been investigated.
