Synthesis, Characterization, Electrical and Sensing Properties of Polyaniline/Zinc Oxide Nanocomposites
In the present investigation, Polyaniline/Zinc oxide composites with various weight percentage of zinc oxide (10, 20, 30, 40 and 50 wt%) were synthesized by in-situ polymerization method. The prepared nanocomposites were characterized by X-Ray diffraction (XRD), Scanning electron microscopy (SEM) and Surface area analyzer (BET). The dc conductivity of the samples was measured as a function of temperature in the range 30–180 °C and it was found that the increasing the concentration of ZnO particles increases the conductivity due to the hopping of polarons and extended chain length of composites. Ac conductivity of the composites was studied with applied frequency and it was found that conductivity increases with increase in frequency. The sensing properties of these composites are also studied at room temperature and 30 wt% shows high sensitivity among all composites due to decrease in resistivity.
