This work calls for a paradigm shift in order to change the operational patterns of self‐regulated membranes in response to chemical signals. To this end, the fabrication of a retrofitting material is introduced aimed at developing an innovative generation of porous substrates endowed with symbiotic but fully independent sensing and actuating capabilities. This is accomplished by transferring carefully engineered plasmonic architectures onto commercial microfiltration membranes lacking of such features. The integration of these materials leads to the formation of a coating surface proficient for ultrasensitive detection and “on‐command” gating. Both functionalities can be synergistically modulated by the spatial and temporal distribution of an impinging light beam offering an unprecedented control over the membrane performance in terms of permeability. The implementation of these hybrid nanocomposites in conventional polymeric porous materials holds great potential in applications ranging from intelligent fluid management to advanced filtration technologies and controlled release.

膜材料的等离子改造：从自我调节转变为按需控制的流体流动

这项工作要求进行范式转换，以响应化学信号改变自调节膜的运行模式。为此，引入了翻新材料的制造，旨在开发具有共生但完全独立的传感和驱动能力的创新型多孔基板。这是通过将经过精心设计的等离激元结构转移到缺乏这种特性的商用微滤膜上来实现的。这些材料的整合导致了涂层表面的形成，该涂层表面足以进行超灵敏检测和“按需”浇口。通过入射光束的空间和时间分布，可以对两种功能进行协同调制，从而就渗透性而言对膜性能进行前所未有的控制。这些杂化纳米复合材料在常规聚合物多孔材料中的应用在从智能流体管理到先进的过滤技术和控释等众多应用中均具有巨大潜力。
