Hydrogen (H)-bonding-integration of multiple ingredients into supramolecular polyelectrolyte nanoporous membranes in water, thereby achieving tailor-made porous architectures, properties, and functionalities, remains one of the foremost challenges in materials chemistry due to the significantly opposing action of water molecules against H-bonding. Herein, a strategy is described that allows direct fusing of the functional attributes of small additives into water-involved hydrogen bonding assembled supramolecular poly(ionic liquid) (PIL) nanoporous membranes (SPILMs) under ambient conditions. It discloses that the pore size distributions and mechanical properties of SPILMs are rationally controlled by tuning the H-bonding interactions between small additives and homo-PIL. It demonstrates that, benefiting from the synergy of multiple noncovalent interactions, small dye additives/homo-PIL solutions can be utilized as versatile inks for yielding colorful light emitting films with robust underwater adhesion strength, excellent stretchability, and flexibility on diverse substrates, including both hydrophilic and hydrophobic surfaces. This system provides a general platform for integrating the functional attributes of a diverse variety of additives into SPILMs to create multifunctional and programmable materials in water.
在水中将多种成分通过氢键整合到超分子聚电解质纳米多孔膜中，从而实现定制的多孔结构、性质和功能，这仍然是材料化学中最首要的挑战之一，因为水分子对氢键的作用具有显著的反作用。本文描述了一种策略，允许在环境条件下直接将小添加剂的功能属性融合到涉及水的氢键组装的超分子聚（离子液体）（PIL）纳米多孔膜（SPILM）中。结果表明，通过调整小添加剂和均聚物 PIL 之间的氢键相互作用，可以合理控制 SPILM 的孔径分布和力学性能。结果表明，受益于多种非共价相互作用的协同作用，小染料添加剂/均聚物 PIL 溶液可用作通用墨水，用于在各种基底上（包括亲水和疏水表面）产生具有强水下粘附强度、优异拉伸性和柔韧性的彩色发光薄膜。该系统为将各种添加剂的功能属性整合到 SPILM 中以在水中创建多功能和可编程材料提供了一个通用平台。
