Polyvinyl alcohol (PVA) nanocomposite films containing low concentrations (0.05-1%) of graphene oxide (GO) and reduced graphene oxide (rGO) were produced via the solution casting method. When electrical properties of nanocomposite films were evaluated, the addition of 1 wt% GO and rGO resulted in a 36% and 45% decrease in the volumetric resistance of the films as well as a decrease in surface resistance of 24.5% and 34.9%, respectively. The maximum tensile strength of 1% GO and rGO-reinforced PVA nanocomposites was found to be similar to 59 MPa and similar to 68 MPa with an increase of 20% and 38% compared to neat PVA films, respectively. The average Young's modulus of 1% GO and rGO-reinforced PVA nanocomposites also increased from 2561 MPa to 3515 MPa and 4219 MPa with an increase of 37% and 65%, respectively. As a result, the electrical conductivity, Young's modulus, maximum tensile strength, thermal properties, and optical absorption of nanocomposite films increased by adding GO and rGO to PVA. The results show that the produced nanocomposite film may be a promising material for packaging applications.eninfo:eu-repo/semantics/openAccessGraphenegraphene oxidenanocompositepolyvinyl alcoholfilmcompositeArticle10.1177/0967391122111332830N/AQ3
