| Abstract |
Self-healing system has been widely investigated by many researchers because of usage for various medical, display, drug delivery system and so on. Therefore, various kinds of polymer are designed and synthesized that can be reversibly assembled and disassembled via covalent and noncovalent bonds.
Here, we fabricated a self-healing gel system without external stimuli. Copolymer between norbornene-based two monomers (M1, M2) synthesized through the ring opening metathesis polymerization (ROMP) and supramolecular gels were fabricated by metal-ligand interactions. (Ni2+, Co2+, Fe2+). These gels showed self-healing properties within a few minutes after cutting without any other additional external stimuli. Supramolecular gels were disassembled by ceric ammonium nitrate (CAN) which can oxidize Fe3+, which cannot bind to terpyridine ligand. Also, the photoactive properties of the supramolecular gel were observed through benzyl amine photo-oxidative coupling reaction. Therefore, norbornene based-supramolecular gels can be applied to fabricating self-repairable functional materials. |
