Remote and efficient infrared induced self-healable stretchable substrate for wearable electronics

•A remote and efficient self-healing flexible polyurethane nanocomposite is reported.•The damages could be healed by NIR due to the photothermal effect of CNTs.•The composites had resistivity which could meet the requirements for ESD materials.•The nanocomposites can be used as substrates for flexible wearable electronics.
