STRETCHABLE SELF-HEALING POLYMERIC DIELECTRICS CROSSLINKED THROUGH METAL-LIGAND COORDINATION

Stanford researchers at the Bao Lab have developed a new self-healing polymer system which employs metal?ligand (Fe2+, Zn2+-bipyridine) interactions. These stretchable self-healing polymeric dielectrics are mechanically robust and stable, with high electrical performance, and low gate current leakage when integrated into OFETs. It is believed to be the first example of integrating such a system into OFETs as gate insulators. This work can provide guidance on the future design of self-healing stretchable dielectric materials based on metal–ligand cross-linked polymers for applications like flexible electronics.
