摘　　要：非溶剂诱导相分离法是工业制备聚合物微孔膜的最常用方法,具有操作简单、微孔结构可控等多种优势。在非溶剂诱导相分离过程中,相分离行为直接决定微孔膜的微孔结构与使用性能,因此相分离过程成膜机理的研究对微孔膜的生产加工与应用具有重大意义。本文介绍了非溶剂诱导相分离法的成型原理以及相分离过程中热力学驱动力和动力学能垒对其微孔结构的影响研究进展,对高性能聚合物微孔膜的制备与应用提供理论指导。Non-solvent induced phase separation is the most common method for the industrial fabrication of microporous polymeric membranes due to its ease of operation and adjustable microporous structure.During non-solvent induced phase separation process,the phase separation behavior directly determines the microporous structure and performance of the membrane,therefore the research of phase separation mechanism is of paramount significance for the fabrication and application of microporous membranes.This review introduces membrane formation mechanism of non-solvent induced phase separation,and the research progress on the impact of thermodynamic driving force and kinetic barrier on the microporous structure,providing theoretical support for the fabrication and application of high-performance microporous polymeric membranes.
