Remotely controlled on-demand functional healing is vital to components that are difficult to access and repair in distance such as satellites and unmanned cruising aircrafts. Compared with other stimuli, a blue laser is a better choice to input energy to the damaged area in distance because of its high energy density and low dissipation through the air. Herein, diselenide-containing polyurethane (PUSe) is first employed to fabricate visible light-responsive stretchable conductive composites with multiwalled carbon nanotubes (MWCNTs). Then, laser-induced remote healing was realized based on the characteristics of long-distance propagation of lasers and the dynamic properties of diselenide bonds. Moreover, the PUSe/MWCNT composite film can be used to transfer an electrical signal in the circuit containing a signal generator. This laser-induced remote healing of conductivity paves the way for developing healing conductors which are difficult to access and repair.

含二硒化物的可拉伸导电复合材料的激光诱导远程愈合

远程控制的按需功能修复对于卫星和无人驾驶巡航飞机等难以远距离访问和维修的组件至关重要。与其他刺激相比，蓝色激光能量密度高，通过空气耗散低，是向远处损伤区域输入能量的更好选择。在此，含二硒化物的聚氨酯（PUSe）首先被用于制造具有多壁碳纳米管（MWCNT）的可见光响应可拉伸导电复合材料。然后，基于激光的长距离传播特性和二硒化物键的动态特性，实现了激光诱导的远程愈合。此外，PUSe/MWCNT复合膜可用于在包含信号发生器的电路中传输电信号。
