Abstract
Moreover, the thermal behavior and crystal structure of membranes prepared using different coagulation bath temperatures were examined by differential scanning calorimetry (DSC) and wide angle X-ray diffusion (WAXD). The results shows that the PVDF membrane precipitated at 60°C had a typical ''α'' form crystal structure. While at 15°C, the PVDF crystallites are a mixture of ''α'' and ''β'' form crystal structure. The crystallization degree of the prepared membrane has not increased with the coagulation bath temperature decreasing.
