Self-healing flexible conductive films have been fabricated, evaluated, and applied. The film is composed of a fragile indium tin oxide (ITO) layer covered with sprayed liquid metal (LM) droplets. Self-healing of electrical conductivity is achieved via spontaneous capillary wicking of LM droplets into cracks/defects of the ITO film. The liquid metal adhering onto the ITO layer can also connect the ITO fragments during bending to keep the overall conductivity of the composite LM/ITO film stable. Stable and reversible electrowetting performance has been achieved with the composite LM/ITO as the conductive film, in either flat or curved states.
自修复柔性导电薄膜已被制备、评估和应用。该薄膜由覆盖有喷涂液态金属（LM）微滴的易碎氧化铟锡（ITO）层组成。通过LM微滴自发的毛细管虹吸作用进入ITO薄膜的裂缝/缺陷中来实现电导率的自修复。附着在ITO层上的液态金属在弯曲过程中也可以连接ITO碎片，以保持复合LM/ITO薄膜的整体电导率稳定。以复合LM/ITO作为导电薄膜，无论是在平面状态还是弯曲状态下，都实现了稳定且可逆的电润湿性能。
