Abstract

The polyvinylidene fluoride/graphene composite membranes were prepared by electrostatic spinning under different conditions. Statistical analysis was conducted on the film-forming properties and liquid absorption rate. Scanning electron imaging technology observed the typical morphologies of the prepared membranes. The influences of process conditions, such as the graphene content, the applied voltage, the needle-collector distance, and the spinning flow rate on the typical morphology of the composites, were compared. It was found that the applied and the needle-collector distance significantly affected the thin film’s film-forming properties. In contrast, the flow rate had a smaller effect on the film properties and morphology. Comprehensive comparison results suggested that the morphology and uniformity of the fibers in the prepared composite material were relatively better at the needle-collector distance of 13 cm with a graphene content of 0.5%, the applied voltage of 18 KV, and the spinning flow rate of 0.12 μL/min.
