Abstract

In this study, the gamma radiation altering effects on the structure and optical properties of Polyvinylidene fluoride (PVDF)/polyaniline (PANI) blend films was investigated. The PVDF and PANI films were synthesized by casting method and gamma irradiated at 50, 100, 125, and 150 kGy, respectively. Following the irradiation, the films morphology and optical properties were characterized by X-ray diffraction technique (XRD), Fourier Transform Infrared spectroscopy (FT-IR) and ultraviolet–visible (UV–Vis) spectrophotometer. The optical constants, absorbance X (λ) and complex dielectric constant were calculated by using Swanepole method whereas the optical dispersion parameters Eo and Ed were determined by Wemple–DiDmenico and the high frequency dielectric constant (ε) was analyzed. XRD patterns revealed the partial crystalline nature of the films before and after irradiation. FT-IR spectral analysis showed a slight shift and increase in the transmittance for all films post-irradiation. In conclusion, irradiating the PVDF and PANI films altered their optical properties suggesting degradation of the polymeric chains upon irradiation and the formation of new cross links.
