近年来，以多巴胺（Dopamine，DOPA）为代表的仿生贻贝物质因其在膜表面改性过程中的简易性、普适性及良好的后功能化潜力在复合膜制备领域备受关注，其在有氧的弱碱性水溶液中能够自聚合生成聚多巴胺（Polydopamine，PDA），但存在自聚合缓慢等问题，加入氧化剂可显著提高自聚合速率。本文重点综述了过硫酸铵、高碘酸钠等氧化剂对于多巴胺自聚合过程、以及复合膜PDA聚合层稳定性、耐污染性能等的影响，并简要介绍了多巴胺氧化自聚合膜表面改性技术在膜生物膜反应器（Membrane biofilm reactor，MBfR）领域中的研究现状，通过多巴胺氧化自聚合膜表面改性技术有望获得具有良好的氧传质性能，生物亲和性以及耐污染性能的复合膜，在MBfR领域具有良好的应用前景。

Dopamine (DOPA), as the typical biomimetic mussel material, has attracted much attention in the field of composite membrane preparation due to its simplicity, universality and good post functionalization potential in the process of membrane surface modification in recent years. Dopamine can generate polydopamine(PDA) through self-polymerization in weakly alkaline aqueous solution, but the self-polymerization is usually a slow process, and the rate of self-polymerization can be increased by adding oxidant. In this paper, the influence of oxidants addition(such as ammonium persulfate, sodium periodate and other oxidants) on dopamine polymerization process, PDA stability and antifouling performance of the composite membrane is mainly reviewed. Furthermore, membrane surface modification technology of dopamine polymerization in membrane biofilm reactor(MBfR) system is also discussed, the composite membrane obtained by dopamine polymerization modification is expected to obtain excellent oxygen mass transfer performance, biological affinity and antifouling properties, and has good application prospect in the field of MBfR.
