ABSTRACT:

Homopolymers of aniline, o-anisidine and their copolymers were synthesized by chemical oxidative polymerization using different ratios of monomers in the feed of H2SO4 medium. The synthesized polymers are characterized by employing Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) 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 (SEM), thermogravimetric analysis (TGA) and dc electrical conductivity respectively. Rod and spherical shaped nanoparticles were observed for PANI and for copolymers respectively. A three step thermal degradation was observed for all the polymers. The electrical conductivities of the copolymers are less compared with PANI, and at higher temperature the conductivities of all the polymers are more or less same. The copolymers show better solubility but lower conductivity than PANI.
