Preparation and properties of skin-like supercapacitor based on silver nanowires

采用微波焊接法结合紫外固化胶制备了具有高导电性的类皮肤银纳米线电极,并将其作为导电电极制备了类皮肤超级电容器.利用扫描电子显微镜表征了银纳米线电极大面积均匀分布,探究了类皮肤银纳米线电极的弯曲循环稳定性.测试了类皮肤超级电容器的电化学性能和机械稳定性,以及在可穿戴电子领域的应用.结果表明:类皮肤银纳米线电极具有高导电性和高机械稳定性,进而保证了类皮肤超级电容器的高面电容以及良好的机械稳定性,且跟随人体运动时仍能正常工作.

With the conductive skin-like silver nanowire(AgNW)electrodes prepared by microwave-welded method and UV-curable adhesive,the skin-like supercapacitors were fabricated.The uniform distribution throughout entire range of silver nanowires was characterized using scanning electron microscope,and the bending cycle robustness was investigated.The electrochemical performance,mechanical robustness,and the application in wearable field were tested.The skin-like silver nanowire electrodes with high conductivity and mechanical stability,ensured the high-area capacitance and outstanding mechanical property of skin-like supercapacitors.In addition,the devices stuck to the hand wrist could function normally by motion.
