Abstract

Abstract

Polyaniline fibres were synthesized by chemical oxidative polymerization using different ratios of monomers in the feed in HCl medium. The synthesized polymers were characterized by employing Fourier transform infrared, UV-visible, X-ray diffraction techniques for understanding the details of the structure of the synthesized polymers. Morphological, thermal, and electrical conductivity of the as synthesized polymers were also studied by employing scanning electron microscopy, thermogravimetric analysis, and electrical conductivity, respectively. A three-step thermal degradation was observed for the polymer. It was observed that yield and intrinsic viscosity of polymer is not regularly dependant on monomer concentration in the feed. The polyaniline show better conductivity than Polythiophene. Copyright © 2018 VBRI Press.
