可拉伸、自修复Janus水凝胶薄膜用于柔性传感器的研究

Stretchable,self-healing Janus hydrogel film for flexible sensors

以银纳米线为无机导电层、水凝胶薄膜为有机柔性层,基于银-硫(Ag-S)配位作用增强Janus水凝胶薄膜导电层与柔性层间的界面作用。同时,为了增强其电学性质,协同银纳米线为导电纳米基元,利用其优异的界面组装能力构筑高导电性Janus水凝胶薄膜。结果表明,动态可逆的Ag-S作用还赋予其在近红外条件下的自修复性能。利用上述获得的Janus水凝胶薄膜应用于柔性传感器,实现实时监测人体的各种运动状态。

Janus hydrogel film is fabricated with silver nanowires as the inorganic conductive layer and hydrogel film as the organic flexible layer.The interfacial interaction between the conductive and flexible layers are enhanced by the silver-sulfur(Ag-S)bonds.To reinforce the electrical property of the film,silver nanowires is taken as the conductive nano units.The results show that the dynamically reversible Ag-S bonds contributes excellent self-healing performance to the obtained Janus films.The flexible sensors with the obtained Janus hydrogel film can be used to monitor various motion states of human body in real-time.
