Polycarbonate/polystyrene composites films were irradiated by 55 MeV Carbon ion beam with fluence ranging from 1 × 10 11 to 1 × 10 13 ions/cm 2 . The polymer composites films were prepared by solution mixing method. The effects of ion beam on structural, optical and surface morphology of PC/PS composites films were investigated by X‐ray diffraction (XRD), UV‐visible spectroscopy (UV‐vis), Fourier Transform Infrared Spectroscopy (FT‐IR) and Optical Microscope. The XRD pattern shows the average crystallite size, percentage of crystallinity and inter‐chain separation, which decreases with increase in ion fluences. UV‐vis spectra show that the energy band gap and transmittance decreases while number of carbon atoms increases with fluences. The FT‐IR spectra evidenced very small change in cross linking and chain scissoring at high ion fluences, while the optical microscopy shows a color change with ion fluence.
