Preparation and characterization of gamma irradiated ZnO/PANI hybrid films

In this study, Zinc Oxide/Polyaniline (ZnO/PANI) hybrid was successfully synthesized using the combination of in-situ chemical oxidative polymerization and simple hydrothermal route method which was sequentially exposed to gamma radiation. X-ray diffraction analysis of non-irradiated and irradiated samples indicates the crystallinity of the ZnO/PANI hybrid and shows no considerable changes after gamma irradiation. Atomic force microscopy analysis shows that the grain size and roughness of the hybrid increase as the irradiation dose increases. Moreover, with increasing radiation dose, the intensity and peak area of photoluminescence spectra increase. According to electrical measurements, the conductivity of the prepared films increases linearly with increasing gamma dose. (author)
