摘要:

Light-driven micropumps, which are based on electroosmosis with the electric field generated by photocatalytic reactions, have been developed as one of the most attractive research topics in chemical micromotors. Until now, most researches in this field mainly focused on directional motions or collective behaviors of microparticles, which lack practical applications. In this paper, we have developed a photowelding strategy to realize photoinduced conductivity recovery of cracked flexible circuits repeatedly. We immerse the circuit in suspension of conductive healing particles and apply photo-illumination to the crack; photocatalysis of pre-deposited pentacene (PEN) layer triggers electro-osmotic effects to gather conductive particles at the crack, leading to conductivity recovery of the circuit. This photowelding strategy has exploited a novel application of light-driven micropumps and photocatalysis in conductivity restoration.
