Abstract
Variations in crystalline structure, optical property, structural bonding in Graphene Oxide (GO) doped polypyrrole (PPy) under gamma irradiation at 100 KGy with effective dose rate of 2.86 KGy per hour have been studied. The crystalline structure has been studied utilizing XRD spectroscopy and it has become clear that as compare to non-irradiated, irradiated sample show more shift toward crystalline nature, this is because of the decrease in d -spacing. The variation in optical properties have been evaluated using UV-VIS spectroscopy, it has been pointed that gamma irradiation reduces the optical band gap due to the chemical reactions, such as chain scissioning etc., induced by gamma exposure, this result is further supported by FT-IR spectroscopy.
