As research on energy harvesting is actively conducted, the material properties of generators have become important. Triboelectric is generated by friction between materials with different charge potentials, which occurs at the surface of the materials. However, when the surface is damaged by mechanical force, it loses its function as a TENG. In this study, after crosslinking through metal coordination using poly(vinyl butyral) (PVB) and metal chloride, a TENG with flexiblity, elasticity and that is capable of slef-healing and shape memory (FE-TENG) is fabricated. Through metal coordination, stretchability and elasticity of PVB has been improved. With these properties, FE-TENG capable of self-healing was fabricated with the help of shape memory function. The functioin as a generator was maintained after healing. In addition, the output voltage of FE-TENG was improved due to the metal ion existing on the surface. |
