Abstract :

Polyaniline (PANI) is one of the important conducting polymers. It can be synthesized by Chemical or Electrochemical routes. Due to unsaturated groups present in the PANI it is known to exhibit conducting properties. Gamma

Irradiation of Polymer is reported to be one of the important methods to alter chemical structure which in turn ings a change in physical
properties. On the other hand Gamma Irradiation treatment is reported enhance conducting properties. Therefore , the authors have investigated Gamma Irradiation in PANI. Fourier Transform Infrared Spectra of non irradiated and irradiated PANI are recorded. Unirradiated
PANI structure of PANI exhibited different absorption bands corresponding to PANI. They include 3900-3450 cm-1 absorption band due to
N-H stretching, 2927 cm-1absorption band due absorption band due to CH/CH2/CH3 groups, 1560, 1495 cm-1 bands are assigned to Benzoic
and Quinoid viations, 1136 cm-1 absorption band due to sin member rings viation. On irradiation a change in absorption of some of these
bands observed. While some new bands are appeared, the results suggest that Gamma Irradiation caused a change in chemical structure of
PANI.
