摘要

离子凝胶由于其离子导电性、柔韧性、稳定性和固有的一致性,作为多功能柔性传感器引起了人们的极大兴趣。然而,将多种功能集成到电离层凝胶中仍然具有很大的挑战性。通过在IL溶液中一步光聚合PIL,我们合成了多功能聚离子液体(PIL)/离子液体(IL)离子凝胶,能够以最小的干扰检测温度和应变刺激。PIL和IL之间的相容性赋予了自粘性能和快速自愈(2 h后效率为82.4%)。此外,PIL/IL传感器对应变(0.987)和温度(0.993)的响应线性度较高,表明温度刺激和应变刺激相互影响很小。这些结果证明了可穿戴电子设备在人体运动检测和温度传感方面的潜力。

Photopolymerized ionogel as strain-temperature flexible sensor with high linearity, self-healing ability and adhesion

Photopolymerized ionogel as strain-temperature flexible sensor with high linearity, self-healing ability and adhesion
Ionogels have attracted significant interest as multifunctional flexible sensors owing to their ionic conductivity, flexibility, stability, and inherent conformability. However, the integration of multiple functions into an ionogels remains significantly challenging. Herein, via a one-step photopolymerization of a PIL in an IL solution, we synthesized multifunctional poly(ionic liquid) (PIL)/ionic liquid (IL) ionogels capable of detecting temperature and strain stimuli with minimal interference. The compatibility between PIL and IL imparts self-adhesive properties and rapid self-healing (82.4 % efficiency after 2 h). Furthermore, the PIL/IL sensor exhibited high response linearity for strain (0.987) and temperature (0.993), indicating that the temperature stimulus and the strain stimulus barely have influence on each other. These results demonstrate the potential of wearable electronic devices for human motion detection and temperature sensing.

期刊介绍: Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
