제목 UV light triggered self-healing composites and multi-functional self-healing polymers
초록 The need of developing self-healing materials in coatings, paints, and flexible substrates now dramatically increases because scratches or cracks formed on surface of protecting materials dramatically accelerate corrosion of the substrate. Here, UV light induced self-healing composites fabricated with zinc oxide nano particles covered by graphene (ZnO-G) and polyurethane (PU) would be introduced. In order to examine self-healing ability of composites, the films were scratched by blade and irradiated under UV. The change in crack size and shape was monitored using optical microscope before and after UV irradiation. In addition, multi-functional self-healing polymers consisting of polycarbonate backbone with urethane bonds and zwitterions would be introduced. The newly synthesized polymers and their films showed flexible, transparent, shape-memorable, self-healable, and triboelectric properties.
