Abstract

Abstract: A self-healable and stretchable light-emitting device with high emission characteristics was developed. To this end, a reversibly crosslinkable polyurethane (rcPU) was synthesized, and ZnS:Cu microparticles were dispersed therein to form an alternating current-driven electroluminescent (EL) film. Transparent electrodes were formed on both surfaces of the EL film for voltage application by using Ag nanowires, which were impregnated under the polymer surface by inverted layer processing and vaporized solvent-assisted embedding method. The developed device exhibited an exceptionally high maximum emission intensity of almost 500 cd/m². In addition, the device maintained its homogeneous emission characteristics even after the application of 100% uniaxial strain with a luminance degradation of less than 40%. Due to the reversible crosslinking characteristics of the rcPU, the device could be recombined even after being completely cut, and the emission properties before cutting could be restored.
