摘要：

近年来纳米气泡因其独特的物理化学性质，在反渗透与纳滤膜的制备过程中受到广泛关注，已成为膜结构精控研究的前沿方向之一。本文系统综述了纳米气泡在聚酰胺膜表面脊谷结构形成中的作用机理，详细探讨了其在界面聚合过程中的形成机制、定向构筑方式以及稳定性调控策略，进一步总结了表面活性剂、溶剂调控、非等温界面等方法对纳米气泡稳定性的影响，并探讨了纳米空隙尺寸与膜层厚度之间的耦合关系及其对膜性能的影响。

Nanobubbles have attracted increasing attention in recent years due to their unique physicochemical properties, particularly in the fabrication of reverse osmosis (RO) and nanofiltration (NF) membranes. This review systematically summarizes the role of nanobubbles in the formation of ridge-and-valley structures on the surface of polyamide membranes. The formation mechanisms, directional construction method and stabilization strategies of nanobubbles during interfacial polymerization are comprehensively discussed. Additionally, the effects of surfactants, solvent regulation, and non-isothermal interfacial conditions on nanobubble stability are analyzed. The coupling relationship between nanovoid size and membrane layer thickness, as well as their combined impact on membrane performance, is also examined.
