Fig. 2. Schematic illustration of the cutting/healing process. (a) Cutting the AgNWs/TPU or AgNWs/PDMS films. (b) Self-healing process induced by contacting the ends of the fracture and exposure to NIR light irradiation. (c) Schematic illustration of the healed AgNWs/TPU or AgNWs/PDMS film. (d) Resistance changes across the fracture area after five cycles of the cutting/healing process for TPU film and PDMS film. (e and f) SEM images of the AgNW layer of the AgNW/TPU film and the AgNW/PDMS film after healing, respectively.
