摘要：

交联改性是一种能有效改善聚合物分离膜性能（如机械性能、热性能等）的方法。选择合适的交联反应与交联剂，能够有效增强聚合物分离膜的机械、热及分离等多方面性能。本文综述了聚合物分离膜的交联改性方法及应用，总结了用于聚合物交联改性的常见物理、化学交联类型及其交联条件、产物结构与性能特点，阐述了交联改性在不同聚合物分离膜领域的应用及交联改性对分离膜性能的影响，并就聚合物分离膜交联改性研究的未来发展进行了展望。

Crosslinking modification is a method that can effectively improve the properties of polymer separation membrane, such as mechanical properties, thermal properties and so on. Selecting appropriate crosslinking reaction and crosslinking agent can effectively enhance the mechanical, thermal and separation properties of polymer separation membrane. This paper summarizes the crosslinking modification methods and applications of polymer separation membranes, summarizes the common physical and chemical crosslinking types and crosslinking conditions, product structure and performance characteristics for polymer crosslinking modification, and expounds the application of different crosslinking modifications in different fields and the influence of crosslinking modification on the performance of separation membranes. The future development of crosslinking modification of polymer separation membrane was prospected.
