The functionalization with phosphotriesterase of poly(isoprene‐b‐styrene‐b‐4‐vinylpyridine)‐based nanoporous membranes fabricated by self‐assembly and nonsolvent induced phase separation (SNIPS) is shown to enable dynamically responsive membranes capable of substrate‐specific and localized gating response. Integration of the SNIPS process with macroporous nylon support layers yields mechanically robust textile‐type films with high moisture vapor transport rates that display rapid and local order‐of‐magnitude modulation of permeability. The simplicity of the fabrication process that is compatible with large‐area fabrication along with the versatility and efficacy of enzyme reactivity offers intriguing opportunities for engineered biomimetic materials that are tailored to respond to a complex range of external parameters, providing sensing, protection, and remediation capabilities.

用于局部渗透门控的生物催化刺激响应不对称三嵌段三元共聚物膜

聚（异戊二烯-b-苯乙烯-b）的磷酸三酯酶功能化通过自组装和非溶剂诱导相分离（SNIPS）制备的基于4-乙烯基吡啶的纳米多孔膜可实现动态响应的膜，从而能够进行底物特异性和局部门控响应。SNIPS工艺与大孔尼龙支撑层的集成产生了具有高湿气传输速率的机械坚固的纺织型薄膜，该薄膜显示出对渗透率的快速和局部量级调制。制造过程的简单性与大面积制造相兼容，酶反应性的多功能性和功效为工程仿生材料提供了诱人的机会，这些仿生材料经过定制可对复杂的外部参数做出响应，从而提供传感，保护和修复能力。
