摘要
研究了非相容性聚合物及不同溶剂对聚偏氟乙烯相转化膜结晶性能的影响。采用红外光谱和DSC方法测定了膜的晶型及结晶度。结果显示,与非相容性材料以适当的比例共混和采用溶度参数较低的溶剂可以降低膜β晶型的含量。
Effect of blending and solvents on the crystallizability of poly(vinylidene fluoride) phase inversion membranes were studied. The crystalline form and crystallinity were measured via Infrared spectrum and DSC technique. The results show that the blending with incompatible polymer in a proper amount and using some solvents with lower solubility parameters could decrease the content of β crystalline form in the membrane.
