Paper Title:
Allotropic Modification Induced by Co60 Radiation on the Structural and Optical Properties of Aromatic Polymers
  Abstract

The structural and optical properties of virgin and gamma rays irradiation on aromatic polymers (PET, PES and Kapton) at various doses varying from 16 to 300kGy. The optical and Structural studies have been observed by using UV-VIS Spectroscopy and Powder X- Ray Diffration techniques. The diffraction pattern of virgin samples shows that polymers are semi crystalline in nature. But due to irradiation, the overall crystalline peak intensity and crystallite size is found to be increased with increasing dose. The UV-Visible absorption spectra show the existence of the maximum absorption, their shifting and broadening as a result of gamma irradiation has been discussed. Finally the value of direct and indirect band gap in virgin and gamma irradiated on aromatic polymers has been decreased.
