Summary Nanocomposite films of PVA (polyvinyl alcohol) with GO (graphene oxide) as organic filler have been synthesized successfully. GO was prepared through modified Hummers method and confirmed by SEM and XRD. Nanocomposites were prepared containing various weight amount of GO (0.1, 0.2 and 0.5%) within PVA matrix. Filmss are casted on clean glass plate through solution casting method and dried followed by. Further the investigation of thermal and mechanical as well as physicochemical properties of nanocomposites are done using respective analysis techniques. Electronic conductivity of the prepared Films are also measured. The value of electronic conductivity enhances as the GO content increases within polymer matrix. Thermal and mechanical analysis shows increment in stability with increasing GO content. Maximum electronic conductivity e.g. 1.95 × 10 −2 Scm −1 was found for G‐5 (0.5%) films.
