In recent years, stimuli-responsive poly(ionic liquids) (PILs) have attracted great attention. The stimuli-dependent properties, particularly the electrical properties, of multiresponsive PILs incorporating functionalized nanoparticles, however, have been less investigated. In this work, we present the synthesis, characterization, and application of PIL films incorporating pH- and thermoresponsive hybrid materials composed of gold nanoparticles functionalized with poly(2-(dimethylamino)ethyl methacrylate) (Au@PDMAEMA). The Au@PDMAEMA nanoparticles exhibit distinct responsiveness to changes in environmental pH and temperature, thereby altering the electrical properties of the PIL films blended with responsive gold nanoparticles (PIL w/Au). This research not only fills a gap in the study of electrical properties of multiresponsive nanoparticle-incorporated PILs but also extends the potential applications of PILs in various fields, including smart sensors and electronic devices.
近年来，刺激响应性聚离子液体（PILs）备受关注。然而，对于包含功能化纳米粒子的多响应性PILs的刺激依赖性性质，特别是电学性质，研究较少。在本工作中，我们展示了包含由聚（甲基丙烯酸2-（二甲氨基）乙酯）功能化的金纳米粒子（Au@PDMAEMA）组成的pH和热响应性杂化材料的PIL薄膜的合成、表征及应用。Au@PDMAEMA纳米粒子对环境pH和温度的变化表现出明显的响应性，从而改变了与响应性金纳米粒子共混的PIL薄膜（PIL w/Au）的电学性质。本研究不仅填补了多响应性纳米粒子掺杂PILs电学性质研究的空白，还扩展了PILs在包括智能传感器和电子设备等各个领域的潜在应用。
