摘要：采用相转化法制备聚丙烯腈膜,分别以高分子聚乙烯吡咯烷酮(PVP-K30和PVP-K90)、聚乙二醇(PEG-2000和PEG-6000)和有机小分子乙二醇、无机盐氯化锂(LiCl)等六种物质作为制备聚丙烯腈膜的添加剂,含量均为3%(质量分数)。并对聚丙烯腈膜的表面和断面结构、水通量、孔隙率、水接触角及对牛血清蛋白(BSA)的截留率等进行了测试及表征。结果表明:以PEG-2000作为添加剂制得的膜的微孔较多,孔径较大,断面为指状结构,具有最大的水通量和孔隙率,达到436L/(m^2·h)和86%;有机小分子乙二醇作为添加剂制得的膜的水通量较低,但对BSA的截留率最高,为93%;聚乙烯吡咯烷酮(PVP)和聚乙二醇(PEG)制得的膜的水接触角较低,最小达到68°,亲水性较好。
Polyacrylonitrile membranes were prepared by phase-inversion method.Polyvinylpyrrolidone(PVP-K30,PVP-K90),polyethylene glycol(PEG-2000,PEG-6000),small organic molecule glycol and inorganic salt lithium chloride(LiCl)were used as additives.The mass fraction of the additive was 3 wt%.The surface and sectional structure,water flux,porosity,water contact angle and BSA rejection of the polyacrylonitrile membranes were studied.The results showed that the polyacrylonitrile membrane with PEG-2000 had many large pores,the sectional structure was sponge-like.It had highest water flux value and porosity,which were 436 L/(m 2·h)and 86%,respectively.The water flux value of the membrane with glycol was low,but the rejection rate of BSA had a highest value of 93%.The membranes with PVP and PEG showed good hydrophilicity,the lowest value of contact angle was 68°.
