Synthesis, characterization and conductivity study of polyaniline prepared by chemical oxidative and electrochemical methods.

Abstract

The present work reports the electrochemical and chemical oxidative synthesis of polyaniline using K2Cr2O7 as an oxidant and H2SO4 as dopant. The conductivity studies of electro chemical synthesis of PANI doped with H2SO4 at various voltages are compared with oxidative synthesized PANI. The confirmation of PANI was done by FT-IR. The crystallinity of the samples was examined by powder X-ray diffraction technique. The various electron transitions present in the PANI were determined by UV-VIS spectroscopy. The electrical conductivity of the synthesized samples was measured by using four probe method at room temperature.
