摘要: Abstract Compared to metallic materials for the use of heat exchanger, polymeric have been enjoyed superior advantages such as corrosion resistance, low density, fouling facile processing and cost. Poly(vinylidene fluoride) (PVDF) is semi-crystalline thermoplastic polymer with excellent thermal electrochemical stability. In order improve its conductivity, graphene/PVDF composites were prepared studied in this paper. The graphene was doped PVDF matrix preparing composite membranes. addition, electric field applied alignment during membrane formation. morphology, structure, conductivity tensile strength membranes before after characterized analyzed. significant improved addition graphene. This tendency further enhanced by application field. When content 20 wt%, increased 212% than that pure it 226% applying maximum obtained when 3 wt%. study may be beneficial development conductive materials.
