It is challenging to synthesize stimuli‐responsive materials with the well‐balanced performance of fast stimulus–response speed, good mechanical strength, multi‐functionality, and deformation diversity as well. This work reports a facile, one‐step thiol‐ene click polymerization strategy for preparation of water/acetone vapor‐responsive hierarchical films, by using diallyl terephthalate (P) as hydrophobic ene‐monomer, 1,4‐diallyl‐1,4‐diazabicyclo [2.2.2]octane‐1,4‐diium bromide (B) as hydrophilic ene‐monomer, and pentaerythritol tetra(3‐mercaptopropionate) (PETMP) as thiol monomer. Besides, by taking advantage of the specific hydrophilic/hydrophobic induction effect of substrate and adjusting the molar ratio of P to B, P60B40‐HPI film is fabricated on hydrophilic substrate “with plasma treatment” whereas P80B20‐HPO film is obtained on hydrophobic substrate “without plasma treatment”. Their “upper‐dense and lower‐porous” structural feature ensured the excellent combination of fast stimuli‐response speed endowed by the porous structure and good mechanical strength enhanced by the upper dense surface. Both films are bidirectional water/acetone vapor‐responsive materials, but their bending directions responding to the stimuli factors are completely opposite. This strategy showed great potential in the development of smart stimuli‐responsive materials.

一步法硫醇-烯点击聚合制备的可控双向水/有机蒸气响应致动器
以快速的刺激响应速度，良好的机械强度，多功能性以及变形多样性的良好平衡性能来合成刺激响应材料是一项挑战。这项工作报告了一种简单的一步式硫醇烯点击聚合策略，该方法通过使用对苯二甲酸二烯丙基酯（P）作为疏水性烯基单体1,4-二烯丙基-1,4-来制备水/丙酮蒸汽响应性多层膜。二氮杂双环[2.2.2]辛烷-1,4-溴化二铵（B）作为亲水性烯基单体，季戊四醇四（3-巯基丙酸酯）（PETMP）作为硫醇单体。此外，通过利用底物的特定亲水/疏水诱导作用并调节P与B的摩尔比，P 60 B 40‐HPI膜在亲水基材上进行“等离子体处理”，而P 80 B 20－HPO膜在疏水基材上进行“未经等离子体处理”。它们的“高密度和低孔隙度”结构特性确保了多孔结构赋予的快速刺激响应速度与上致密表面增强的良好机械强度的完美结合。两种膜都是双向的水/丙酮蒸气响应材料，但是它们响应刺激因素的弯曲方向却完全相反。该策略在开发智能刺激响应材料方面显示出巨大潜力。
