摘要：

作为一种受生物细胞膜启发而人工合成的新型功能膜，环境响应型智能膜可在环境中的物理/化学刺激发生变化时，基于膜表面和膜孔内的智能高分子链的环境刺激响应特性，改变智能膜表面的物理化学特性甚至膜微观结构，最终自主调节膜的选择性与渗透性。由于兼具膜基材的良好机械强度和新的环境刺激响应性能，智能膜比传统分离膜具有更高效、广阔的应用前景。综述了近年来环境响应型智能开关膜应用于抗污染或自清洁、物质分离、物质检测、控制释放和反应催化等领域的研究现状，着重介绍了它们应用在不同领域时的作用机理与典型实例。

As a new type of artificially synthesized functional membrane inspired by biological cell membranes, the environmentally responsive smart membranes can change its surface physical and chemical properties and even the microstructure when the physical/chemical stimuli in the environment changes, and as a result, they have self-regulated selectivity and permeability. It is attributed to the environmental stimuli-responsive characteristics of the intelligent polymer chains on the membrane surface and inside the membrane pores. Due to both the satisfactory mechanical property of the membrane substrate and the environmental stimuli-responsive performance newly added, the smart membranes have more efficient and broad application prospects than traditional membranes. The current progress in the broad application fields of environmental responsive smart gating membrane such as anti-fouling or self-cleaning, substance separation and detection, controlled release and reaction catalysis is reviewed. The mechanism and typical examples of the applications of smart gating membranes in different fields are emphasized.
