Abstract: The effect of high electronic excitation triggered swift heavy ion irradiation  on the morphological, structural and electrical properties of Ag-polypyrrole (Ag-PPy) composite films is investigated under the influence of by 120 MeV Ni9+ ion beam having fluences ranging from 1×1011 to 3×1012 ions/cm2. The induced modifications were studied by using various characterization techniques, such as, Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), and Raman spectroscopy. The Raman spectra of Ag-PPy composite films exhibit the anti-symmetrical formation of peaks designated as broad D and comparatively sharp G band. The size of the sp2 phase in the structure was calculated by the intensity ratio in these bands. XRD analysis showed the formation of large size crystallite in the amorphous regions of the composite films with an increase in the ion fluence. SEM images display the symmetrical growth in the surface morphology of the composite films with respect to increasing ion fluence. An attempt has been made to correlate the observed results with previously reported data to make the current investigation more enlightening.
