In recent years, the advent of highly deformable and healable electronics is exciting and promising for next-generation electronic devices. In particular, self-healable triboelec. nanogenerators (SH-TENGs) serve as promising candidates based on the combination of the triboelec. effect, electrostatic induction, and self-healing action. However, the majority of SH-TENGs were devised with weak polymeric networks that are healed with reversible supramol. interactions or disulfides, thus resulting in poor mech. properties and low resistance to creeping. To address this issue, the authors demonstrate the integration of mech. strong and self-healable poly(hindered urea) (PHU) network in the fabrication of effective TENGs. The designed PHU network is flexible but shows greater mech. property of tensile strength ≤1.7 MPa at break. The network is capable of self-healing quickly and repeatedly as well as being reprocessable under mild conditions, enabling the recovery of triboelec. performances after the complete healing of the damaged surfaces. Also, the interfacial-polarization-induced enhancement of dielec. constant endows SH-TENG with the highest triboelec. output performance (169.9 V/cm2) among the reported healable TENGs. This work presents an avenue to the development of mech. energy-harvesting devices and self-powered sensors with excellent stretchability, high recoverability, and good mech. strength.
