Abstract

Abstract:

Polypyrrole (PPY) is a conducting polymer that displays rich variety in morphology, partially crystalline, and partially disordered. Investigations are still being pursued to make them more conducting and crystalline. In the present investigation, conducting polymer polypyrrole (PPY) thin films have been prepared by the electrochemical polymerization technique and were irradiated by 100 MeV, silver (Ag8+), swift heavy ions (SHI) at various fluences of 1010, 1011 and 1012 ions / cm2 . A comparative study of samples before and after irradiation has been performed by using various techniques such as Fourier Transform Infrared Spectroscopy (FTIR), Atomic force microscopy (AFM), X-ray diffraction (XRD). With increase in fluence, the surface structure of PPY films becomes smoother, the crystallinity increases and the conductivity increases by two orders. The present investigations open up the scope for the applicability of irradiated conducting polymers with defined conductivity for sensor applications.
