Effect of Thermal Treatment on the Physical Properties of Electrospun PVDF Membrane

摘要

The electrospinning technique was used to produce poly (vinylidene fluoride) (PVDF)membrane.Thermal treatment was introduced to improve the mechanical property and dimensional stability.In this paper,the PVDF membranes before and after thermal treatment were characterized by Scanning electron microscope (SEM),differential scanning calorimeter (DSC) and wide angle X-ray diffraction (WAXD),tensile testing.The crystallinity,tensile property,as well as melting temperature changed with the treated temperature.The results hows that thermal treatment could notably increase the tensile property of electrospun PVDF membrane and 160°C is a proper temperature for thermal treating.
