Study of electrical and dielectric properties as an effect of nanoparticle concentration and UV irradiation of PVA-Ag nanocomposites

PVA incorporated with different concentrations of silver nanostructures were prepared using chemical reduction technique and these prepared nanocomposites were exposed to UV irradiation for 2, 3 and 4 h. Fundamental aim is to investigate tailoring of conductivity and dielectric parameters due to changes of concentration of nanoparticles and irradiation time. XRD was done to study structural characterization. FE-SEM and EDX were employed for structural and morphological analysis of nanocomposites. AC conductivity was observed to increase and values of dielectric constant were noticed to decrease whereas dielectric loss was observed to show increment with increasing concentration of nanostructures and UV exposure.
