In recent years, significant advances have been made in the field of functionalized membranes. With the functionalization using various materials, such as polymers and enzymes, membranes can exhibit property changes in response to an environmental stimulation, such as heat, light, ionic strength, or pH. The resulting responsive nature allows for an increased breadth of membrane uses, due to the developed functionalization properties, such as smart-gating filtration for size-selective water contaminant removal, self-cleaning antifouling surfaces, increased scalability options, and highly sensitive molecular detection. In this review, new advances in both fabrication and applications of functionalized membranes are reported and summarized, including temperature-responsive, pH-responsive, light-responsive, enzyme-functionalized, and two-dimensional material-functionalized membranes. Specific emphasis was given to the most recent technological improvements, current limitations, advances in characterization techniques, and future directions for the field of functionalized membranes.
近年来，功能化膜领域取得了重大进展。通过使用各种材料（如聚合物和酶）进行功能化，膜能够响应热、光、离子强度或pH等环境刺激而表现出性质变化。由于所开发的功能化特性，如用于尺寸选择性去除水中污染物的智能门控过滤、自清洁防污表面、增加的可扩展性选项以及高灵敏度分子检测，由此产生的响应特性使得膜的使用范围得以扩大。在本综述中，报告并总结了功能化膜在制备和应用方面的新进展，包括温度响应型、pH响应型、光响应型、酶功能化和二维材料功能化膜。特别强调了功能化膜领域的最新技术改进、当前局限性、表征技术进展以及未来方向。
