摘　　要：本文在聚4-甲基-1-戊烯(PMP)/肉豆蔻酸(MA)体系的基础上,添加水溶性无毒非溶剂PolarClean,使得PMP/MA/PolarClean体系发生复合相分离,成功获得了表面致密、内部具有双连续梯度孔结构的PMP中空纤维膜;系统地探究了MA/PolarClean配比,以及PMP质量分数对中空纤维膜的形貌、强度、泡点、透气量等性能的影响。结果表明,当MA/PolarClean质量比为5∶1,且PMP质量分数为40%时,PMP中空纤维膜的综合性能与商品膜相仿,展现了良好的应用潜力。On the basis of the poly(4-methyl-1-pentene)(PMP)/myristic acid(MA)system,PolarClean,a non-solvent for PMP with water-soluble and non-toxic,was added to enable the PMP/MA/PolarClean system to undergo hybrid induced phase separation(HIPS),and successfully obtaining PMP hollow fiber membranes with dense surface and bicontinuous gradient pore structure inside.A systematic investigation was conducted on the effect of the MA/PolarClean mass ratio and PMP mass fraction on the morphology,strength,bubble point,nitrogen permeability,and other properties of hollow fiber membranes.The results showed that when the mass ratio of MA/PolarClean was 5∶1 and the PMP mass fraction was 40%,the comprehensive performance of PMP hollow fiber membranes was similar to that of commercial membranes,demonstrating good application potential.
