| 摘 要： | 基于热致相分离基本原理,通过熔融共混聚偏氟乙烯/CaCO3/邻苯二甲酸二丁酯三元体系,制备了聚偏氟乙烯膜.考察了稀释剂和CaCO3含量对膜微观结构及拉伸强度的影响,以及CaCO3含量对聚偏氟乙烯结晶温度、结晶度的影响.结果显示,稀释剂和CaCO3含量对膜微观结构和拉伸强度影响显著;而CaCO3含量虽然对共混体系结晶度影响不太明显,但是对其结晶温度有较为显著的影响.

| Abstract: | PVDF membranes were prepared via thermally induced phase separation method by melt-blending the ternary system of polyvinylidene fluoride/CaCO_3/diluent.The effects of the diluent and CaCO_3 content on the microstructure and tensile strength of membranes,and the effects of CaCO_3 content on the crystallization temperature and crystallinity of the blend system were studied.The diluent and CaCO_3 content were proved to be the critical factors affecting the microstructure and tensile strength of the membrane,and CaCO_3 content was showed a considerably effect on the crystallization temperature of PVDF,but no evident effect on the crystallinity of PVDF. |
