The synthesis and characterization of demulsifying poly vinylidene Fluoride (PVDF) Disc

Abstract

AbstractOil/water separation is still a challenging universal task. Here we fabricated an amphiphilic polymeric (APD) PVDF disc that can be used to separate free oil/water mixtures and recover the pure water from W/O emulsions. The modification of the disc includes deposition of copper oxide (CuO) was integrated on the surface via the impregnation method; the CTAB was used as a porogen to increase the roughness of the surface, Morphology of the disc was investigated by SEM and the result showed the nanoparticles were entrapped on the surface and inside the disc. FTIR results strongly predicted the correlation of CTAB, PVDF, and CuO nanoparticles of the modified disc. Separation and wettability test of the FRR% (Flux recovery ratio), permeate flux/oil rejection coefficient (R %) and the water-uptake test confirmed the antifouling properties, permeability of water, oil-rejection, and porosity of the disc. The purpose of impregnation CuO enhanced the hydrophilicity and anti-fouling properties of the PVDF disc.
