Abstract High-energy ion beam irradiation of the polymers is a good technique to modify the propertiessuch as electrical conductivity, structural behaviour and mechanial properties. Polyaniline thin films doped withhydrochloric acid (HCl) were prepared by oxidation of ammonium persulphate. The effect of Swift Heavy Ionsirradiation on the electrical and structural properties of polyaniline has been measured in this study. Polyanilinefilms were irradiated by oxygen ions (energy 80 MeV, charge state O+7) with fluence varying from 1 × 1010 to 3× 1012 ions/cm2. The studies on electrical and structural properties of the irradiated polymers were investigatedby measuring V-I using four probe set-up and X-ray diffraction (XRD) using Bruker AXS, X-ray powderdiffractometer. V-I measurements shows an increase in the conductivity of the film, XRD pattern of the polymershows that the crystallinity improved after the irradiation with Swift Heavy Ions (SHI), which could be attributedto cross linking mechanism.
