The development of hydrogel–organogel bilayer films has greatly promoted the application of asymmetric structures in bionics, biointegrated electronics, and other basic industries. However, the ability to bond the hydrogel and organogel tightly remains a significant challenge. Herein, we propose a simple one-pot method for the fabrication of multiresponsive hydrogel–organogel bilayer films, consisting of a hydrophobic poly(butyl acrylate) (polyBA) layer, a salt-/thermo-responsive poly(3-(1-(4-vinylbenzyl)-1H-imidazol-3-ium-3-yl)propane-1-sulfonat) (polyVBIPS) layer, and interfacially distributed vinyl-functionalized nanoparticles. The presence of functionalized nanoparticles leads to strong adhesion between the hydrogel and organogel via copolymerization between the hydrogel and organogel precursors. Since the hydrophobic organogels and hydrophilic hydrogels exhibit independent swelling–shrinking behaviors, the resultant bilayer films undergo rapid, large-amplitude, reversible, and repeatable bidirectional bending under various external stimuli, such as temperature, salt solutions, and organic solvents. The excellent multiresponsive bending behaviors were further demonstrated in biomimetic manipulators which show excellent “capture–transport–release” complex mechanical motions. Additionally, on the basis of the salt response of polyVBIPS, a conceptual hydrogel–organogel bilayer pipe has been designed for the removal of oil/seawater pollution. Overall, this work provides a new strategy for enhancing interfacial strength in immiscible binary systems. A new hydrogel–organogel bilayer film has been developed with great potential for use in the applications of soft robots and sewage treatment systems.

天然脂质启发的水凝胶-有机凝胶双层执行器，具有坚固的界面和多响应，快速和可逆的行为
水凝胶-有机凝胶双层膜的发展极大地促进了不对称结构在仿生学，生物集成电子学和其他基础工业中的应用。然而，紧密结合水凝胶和有机凝胶的能力仍然是一个重大挑战。在这里，我们提出了一种简单的一锅法制造多响应水凝胶-有机凝胶双层薄膜的方法，该薄膜由疏水性聚丙烯酸丁酯（polyBA）层，盐/热响应性聚（3-（1-（ 4-乙烯基苄基）-1 H-imidazol-3-ium-3-yl）propane-1-sulfonat）（polyVBIPS）层和界面分布的乙烯基官能化纳米粒子。官能化的纳米颗粒的存在通过水凝胶与有机凝胶前体之间的共聚而导致水凝胶与有机凝胶之间的强粘附性。由于疏水性有机凝胶和亲水性水凝胶表现出独立的溶胀-收缩行为，因此所得的双层膜在各种外部刺激（例如温度，盐溶液和有机溶剂）下会经历快速，大幅度，可逆和可重复的双向弯曲。仿生操纵器进一步展示了出色的多响应弯曲行为，该仿生操纵器表现出出色的“捕获－运输－释放”复杂机械运动。此外，根据polyVBIPS的盐反应，设计了一种概念性的水凝胶-有机凝胶双层管，用于去除油/海水污染。总的来说，这项工作提供了一种新的策略来增强不混溶二元系统的界面强度。已开发出一种新型的水凝胶-有机凝胶双层薄膜，具有很大的潜力，可用于软机器人和污水处理系统。
