Zinc Oxide (ZnO) is an attractive oxide semiconductor material that particularly known
for its well electrical, optical and piezoelectric properties, has been widely used in
numerous applications. The current paper explores the preparation of PVA composites
by doping with zinc oxide (ZnO) particles using the method of coagulation and solvent
casting technique. Scanning electron microscopy (SEM) was used to observe the
morphology, dispersion, and homogenous particle distribution of ZnO on the surface
of the PVA films. The FTIR spectroscopy suggests that the formulation of complexes
occurring between ZnO and the PVA main chain is due to inter or intra molecular
hydrogen bonding. UV-vis spectra explore the dramatic decrease in the optical energy
gap of particles doped polymer composites. Then the composite also had been studied
of their conductivity by using Electrochemical Impedance Spectroscopy (EIS). The
conductivity of the composite had been known from this study.
