摘要: 以聚4-甲基戊烯-1(PMP)为膜材质、分别以环己烷、三氯乙烯以及环己烷/三氯乙烯为溶剂,以浇铸法制备了PMP的均质致密膜。研究了不同溶剂体系的相对溶解能力和挥发速度对PMP膜结晶度和形态结构的影响,并对成膜的渗透汽化特性的影响进行了研究。Abstract: Using Poly(4 methyl pentene 1)(PMP) as a membrane material and cyclohexane, trichloroethylene, mixture of cyclohexane and trichloroethylene as solvents, these solutions were cast to form homogeneous dense membranes, respectively.
