CHEMICAL SYNTHESIS, CHARACTERIZATION AND ELECTRICAL CONDUCTIVITY BEHAVIOUR OF POLY(2- CHLORO ANILINE- CO- 2 –METHOXY ANILINE) - BLEND - SODIUM ALGINATE

Abstract

This paper focuses on the chemical synthesis and characterization of poly(2-chloro aniline-co-2-methoxy  aniline) - blend - sodium alginate (poly(OCA-co--OMA)/NaAlg) using HCl as dopant and ammonium persulphate as an initiator. The copolymer blend synthesised is soluble in DMSO, DMF and CHCl₃ and shows better thermal, and electrical properties when compared to the pure copolymer. FTIR and UV-Vis Spectroscopy, XRD, TGA and DSC are used to characterize the blend. The particle size as calculated using Debye Scherrer equation is of the nanometer range. The poly(2-chloroaniline–co-2-methoxy aniline)/NaAlg blend shows an electrical conductivity value of  2.15x10^-4Scm^-1 which is in the  semiconducting range.
