Preparation of Poly Aniline by Chemical Oxidative Method and Its Characterization


The present work reports the oxidative synthesis of poly aniline using K2Cr2O7 as an oxidizing agent and H2SO4 as dopant. The synthesized polymer was characterized by solubility test and UV-visible spectroscopic technique. The synthesized polymer (poly aniline) was insoluble in ethanol, acetone, benzene and water. The absorbance of UV-visible spectra shows two reductive peaks at some wake length. The band observed at 327 - 365 nm for the PANI samples corresponds to n-p* transitions of aniline and the broad band at 600 - 620 nm is due to n-p* transitions of quinineimine groups.
