preparation and characterization of highly hydrophobic PVDF-graphene fibrous membrane

The fluorinated polymer fibrouse films are an important class of hydrophobic nanomaterials which have the low surface energy and high specific surface area. In this work the nano-fibrous composite membrane sheets were prepared by the electro-spinning of the Polyvinylidenefluoride-graphene (PVDF-G), blend solution as the main precursor. Preapared membrane possess hydrophobic charrectristics with the water contact angle up to 160°. These kinds of membranes have potencial appliactions in the separation proceses where the membrane pores dryness required during the process.
