摘要
聚乳酸是一种可持续的绿色环保高分子材料,具有明显的可再生优势,已经被制成各种类型的分离膜,有望在分离和纯化领域替代难降解的高分子膜,既能节约石化资源又能减少白色污染.本文分析了浸没沉淀相转化法、热致相分离法和静电纺丝法制备聚乳酸分离膜的优缺点,评价了聚乳酸膜的4种亲水改性方法,即物理共混、表面偏析、表面接枝和表面生物黏合,总结了聚乳酸被制成微滤膜、超滤膜、电纺微滤膜和致密膜等在分离与纯化领域的应用进展,最后指出聚乳酸分离膜目前存在的问题,并给出下一步改进方向,以期能为今后的相关研究工作与工业应用提供有益的参考.
Poly(lactic acid)separation membrane is a sustainable and green polymer membrane,and has attracted extensive attention.Firstly,three fabrication methods were summarized comprehensively,including non-solvent induced phase separation,thermally induced phase separation and electrospinning.Secondly,four hydrophilic modification approaches were also diccussed in detail,such as physical blending,surface segregation,surface grafting and surface bioadhesion.Thirdly,various applications of poly(lactic acid)separation membrane were briefly described.Finally,some useful suggestions were proposed to improve the peformance of poly(lactic acid)membrane and enlarge the application of poly(lactic acid)membrane.
