由于其在设计柔性能量存储装置、致动器和传感器中的潜力，在实际应用中期望具有抗冻性和耐热性并且具有高极限拉伸强度的凝胶。在这里，一个简单的方法，用于制造离子液体（IL）为基础的点击离子凝胶使用硫醇烯点击化学在温和的条件下报告。这些点击离子凝胶在10，000次疲劳循环后继续表现出优异的机械性能和弹性。此外，由于离子液体的几种独特性质，这些点击离子凝胶在宽温度范围（-75 ° C至340 ° C）内表现出高离子电导率，透明度和不可燃性性能。基于点击离子凝胶的摩擦电纳米发电机具有优异的机械、冻融和热稳定性。点击离子凝胶的这些有前途的功能将促进灵活和安全的设备设计的创新应用。
Gels that are freeze-resistant and heat-resistant and have high ultimate tensile strength are desirable in practical applications owing to their potential in designing flexible energy storage devices, actuators, and sensors. Here, a simple method for fabricating ionic liquid (IL)-based click-ionogels using thiol-ene click chemistry under mild condition is reported. These click-ionogels continue to exhibit excellent mechanical properties and resilience after 10,000 fatigue cycles. Moreover, due to several unique properties of ILs, these click-ionogels exhibit high ionic conductivity, transparency, and nonflammability performance over a wide temperature range (-75 degrees to 340 degrees C). Click-ionogel-based triboelectric nanogenerators exhibit excellent mechanical, freeze-thaw, and heat stability. These promising features of click-ionogels will promote innovative applications in flexible and safe device design.
