Paper Abstract

A novel method is developed to prepare PVDF based graphene oxide (GO) nanocomposites using a co-solvent approach involving water and DMF. Nanocomposite films are prepared by solution casting the GO-PVDF solution. TEM images of these nanocomposites show better dispersion of GO in the PVDF prepared using the co-solvents as compared to the films made only using DMF. Following solvent evaporation, GO/PVDF nanocomposites are hot pressed at 150 °C, well below the melting temperature of PVDF, to maintain the dispersion of GO fillers while partially reducing the GO to functionalized graphene sheets. Dielectric constant and electrical conductivity of the nanocomposites show remarkable increase compared to values for PVDF for a low 0.005 weight fraction. The effect of the presence of GO and the hot press on the morphology of PVDF are discussed.
