Gamma irradiation: an efficient way to enhance current carrying properties of Ag/Ppy composite

We report two step electrochemical synthesis of Silver/Polypyrrole (Ag/Ppy) composite with chronopotentiometric deposition of Ppy on stainless steel (SS), followed by decorating Ag nanopartilces on Ppy via cyclicvolammetry (CV) with optimized process parameters. The synthesized Ag/Ppy composite films are then exposed to Co-60 Gamma irradiation source having an average energy 1.25 MeV for 0, 5 and 15 kGy dose ranges. Structural analytical studies show that Ag particles are firmly attached with Ppy. Significant enhancement in current density confirms that Ppy is precisely stable and appropriate coupling base material for Ag nanoparticles. The maximum extracted current density from Ag/Ppy is 6.56 mAcm − 2 at 15 kGy.
