Poly (vinylidene fluoride) (PVDF) / poly(methyl methacrylate) (PMMA) composite membrane was produced by the electrospinning technique. Thermal treatment was introduced to improve the mechanical property and dimensional stability. In this paper, the PVDF/PMMA membranes before and after thermal treatment were characterized by Scanning electron microscope (SEM), differential scanning calorimeter (DSC) , pore size and porosity test, electrolyte uptake test and tensile test. The pore size, porosity, electrolyte uptake rate, tensile property, as well as melting temperature and crystallinity changed with the treated temperature. The results show that thermal treatment could notably increase the tensile property of electrospun PVDF/PMMA composite membrane and 160°C is a proper temperature for thermal treating.
