For most stimuli-responsive polymer materials (SRPMs), such as polymer gels, micelles, and brushes, the responsive mechanism is based on the solubility or compatibility with liquid media. That basis always results in distorting or collapsing the material's appearance and relies on external liquids. Here, a novel kind of SRPMs is proposed. Unlike most SRPMs, liquid is stored within special domains rather than expelled, so it is deforming-free and relying on no external liquid, which is referred to as self-storage SRPMs (SS-SRPMs). The facile and universal route to fabricate SS-SRPMs allows for another novel family of SRPMs. Furthermore, it is validated that SS-SRPMs can drastically respond to outside temperature like switchers, especially for optical and electrochemical responses. Those features hold prospects for applications in functional devices, such as smart optical lenses or anti-self-discharge electrolytes for energy devices.
对于大多数刺激响应性聚合物材料（SRPMs），如聚合物凝胶、胶束和刷状聚合物，其响应机制基于与液体介质的溶解性或相容性。这种基础总是导致材料外观变形或塌陷，并且依赖于外部液体。在此，提出了一种新型的SRPMs。与大多数SRPMs不同，液体存储在特殊区域内而不是被排出，因此它无变形且不依赖外部液体，这被称为自存储SRPMs（SS-SRPMs）。制造SS-SRPMs的简便通用方法催生了另一类新型的SRPMs。此外，已证实SS-SRPMs可以像开关一样对外部温度做出剧烈响应，特别是在光学和电化学响应方面。这些特性为其在功能器件中的应用带来了前景，如智能光学镜片或用于能量装置的抗自放电电解质。
