摘 要:采用浸没沉淀相转化法制备非对称聚偏氟乙烯(PVDF)超滤膜,以纯水通量和截留率为指标,优化了PVDF超滤膜制备条件。实验结果表明,以聚乙烯吡咯烷酮(PVP)为致孔剂,搅拌温度60 ℃,搅拌时间8 h,基底PVDF质量分数10%,PVP质量分数1.0%,优化条件下PVDF超滤膜水通量为224.11 L/(m2·h),截留率为75%;孔隙致密、均匀,平均孔隙率为68.5%,平均抗拉强度为6.00 N/mm2。所获得的PVDF超滤膜性能优良,有望用于制药行业中去除大分子物质。

Abstract:Asymmetric polyvinylidene fluoride ultrafiltration (PVDF) membrane was prepared by immersion precipitation phase inversion method. With pure water flux and interception rate as indexes, the preparation conditions of PVDF ultrafiltration membrane were optimized. The results showed that using PVP as pore-forming agent, stirring temperature was 60 ℃; stirring time was 8 h; the mass fraction of PVDF on the substrate was 10%; and the mass fraction of PVP was 1.0%. The water flux of this obtained PVDF ultrafiltration membrane was 224.11 L/(m2·h) and the rejection rate was 75%; the porosity was compact and uniform; the average porosity was 68.5%; and the average tensile strength was 6.00 N/mm2. This PVDF ultrafiltration membrane has excellent performance and is expected to be used in the pharmaceutical industry to remove macromolecular substances.
