The conducting polymer polyaniline and PANI/ZnO nanocomposites were synthesized by in-situ polymerization method at 0-5 °C temperature with ammonium persulphate as an oxidising agent. The optical band gap of PANI/ZnO nanocomposites have been studied at different weight percentage such as 10%, 30% and 50%, at room temperature. The XRD pattern confirmed the hexagonal wurtzite structure of the ZnO product. The particle size was calculated by using the Debye-Scherrer relation and it was found to be in the range of 20-50 nm. The obtained absorption spectra at 385 nm is the charectestic peak of ZnO and observed for all weight percentages of nanocomposites. The peaks occured at 300 nm and 470 nm confirms the formation of polyaniline in the nanocomposites. Further the dielectric properties such as dielectric constant, dielectric loss and AC conductivity for the PANI with PANI/ZnO composites at different weight percentages are studied as a function of frequency in the range 5 Hz–35 MHz at room temperature.
