Exploring the properties of lead oxide and tungsten oxide based graphene mixed nanocomposite films

This work reports the possibility of mixing metal oxides along with graphene and polymer to form Metal Oxide-Graphene-Polymer films. The metal oxides used in this work were lead Oxide $(\mathrm{PbO})$ and tungsten oxide $(\mathrm{WO}_3)$. Polyvinylidene fluoride (PVDF) is the polymer, which is used as matrix in preparation of these metal oxide and graphene mixed nanocomposite films. Metal Oxide-Graphene-PVDF films were developed using a chemical technique called solvent casting. The prepared films were characterized using techniques like FE-SEM, XRD and FT-IR to understand its morphological, crystalline and functional properties. I–V characteristics were analyzed using four-probe techniques. The developed Metal Oxide-Graphene-PVDF films have potential applications in a wide range of fields and particularly for electronic applications. The ability of these films to be used as electronic components in devices was explored.
