| Popis: | In this study, the conductive polymer polyaniline/poly(vinyl acetate) PANi/PVAc composite thin films were synthesized by chemical oxidative polymerization method with ammonium per sulfate as an oxidizing agent in methanol. The as-synthesized composite were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), ultraviolet–visible (UV–Vis) spectroscopy and photoluminescence (PL) measurement. The temperature dependence of DC electrical conductivity measurements were carried out through a two probe technique. The broad peak was found in the PL spectra of the obtained composite at around 450 nm, suggested that the obtained composite retains more charge generation efficiency. The enhancement in the optical and electrical properties of PANi/PVAc composite makes it as a novel candidate in various optoelectronic applications. |
