Abstract
Semicrystalline polycarbonate (PC) films were irradiated under vacuum at room temperature by C +5 beam of 55 MeV energy at fluences of 3 × 10 11 and 3 × 10 13 ions cm 2. Ion induced modifications were studied by X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and thermally stimulated discharge current (TSDC) techniques. With increasing ion fluence significant loss of average crystallite size, percentage crystallinity, stability and glass transition ( T g ) temperature were observed. TSDC shows that activation energy, released charge, α-relaxation peak, and charge carrier mobility decrease while relaxation time and peak current increase.
