摘　　要：聚丙烯微孔膜的表面工程研究主要涉及:强调膜表面性质的膜过程开发、膜表面修饰与功能化方法的建立和优化、膜表面结构的表征及其与膜分离性能的关联,旨在深化对聚丙烯微孔膜材料表面特性的认识,进而拓展其应用范围.基于聚丙烯微孔膜表面的疏水性,首先简要介绍了气-液两相膜接触器传质行为的理论研究,随后重点总结了聚丙烯微孔膜表面亲水化与抗污染性能研究、表面仿生修饰与生物功能分离膜构建等方面的研究进展.Surface engineering of microporous polypropylene membranes （MPPMs） embraces a series of studies. It mainly includes the exploitation of membrane processes focusing on the surface properties of MPPMs, the establishment and optimization of surface modification and functionalization strategies for MPPMs, the characteri- zation of surface structure, and the association of surface structure with separation performance. The purlmse of surface engineering is to thoroughly understand the surface characteristics of MPPMs and then broaden their application fields. In this review, a brief introduction of theoretical research is firstly given, which is on the mass transfer behavior of gas- liquid membrane contactor based on the surface hydrophobicity of MPPMs. Subsequently, recent development in the hydrophilization to improve antifouling properties, the biomimetic modification, and the biological functionalization for the surfaces of MPPMs are summarized.
