【摘要】 采用相转换法制备了平均孔径小1μm 的新型含酞侧基可溶性聚芳醚酮(PEK-C)微孔滤膜,讨论了膜液组分、添加剂含量、凝固浴温度等参数对膜性能的影响,用扫描电镜观察了膜的形态结构,并对该膜的化学稳定性和机械性能进行了测试更多还原

【Abstract】 A novel polyetherketone(PEK-C) microfiltration membrane pre-pared by a phase inversion technique was reported in this paper.The standard properties of PEK-C MF membrane can be summarizedas follows.thickness 100—200μm; average pore size<1.0μm;over-all porosity 75—90%; pure water flux 50—500ml/cm~2hr(under2.0kg/cm~2 applied pressure); tensile strength 3.0—5.0MPa (25℃).The main factors(polymer concentration, additiv content andtemperature of gelation) effecting the membrane performances havebeen studied.The morphological structures of the PEK-C MF membrane wereobserved by SEM.The results indicated that membranes have open porespongy structures.更多还原
