A transparent electrode comprising Ag nanowires (AgNWs) and a polyurethane equipped with Diels-Alder adducts as crosslinkers was successfully fabricated to realize a thermally amendable electrode. To bury the AgNWs at the surface of the polymer, we designed an effective transfer method using a Kapton film as a preliminary supporter and employing a roller-based laminator equipped with a heater. Intense pulsed light (IPL) was employed to provide localized heat to the AgNW-polymer composite layer. By virtue of the efficient heating mechanism, a composite electrode that was separated by a knife could be healed and its conductivity recovered in a very short period of less than 1 ms. Only one or two 500 ms pulses of IPL were enough to effectively repair the damaged electrodes. Owing to the reversible Diels-Alder reaction, reproducible healing was also observed.
