Abstract

Polyvinyl alcohol (PVA) is valued for its transparency and film-forming ability, but its limited chemical reactivity and weak nanofiller interactions restrict functional tunability. Partially oxidized PVA (OPVA), enriched with ketone and hydroxyl groups, provides a versatile scaffold for nanocomposite design. Transparent OPVA–graphene oxide (GO) films were fabricated via dopant-free aqueous casting with low GO loadings (0.5–1.5 wt%). Read More
