▎ 摘　　要

NOVELTY - Sunlight-driven self-healing paint comprises 2-50 pts. wt. organic resin, 0.1-5.1 pts. wt. photothermal material and 2-25 pts. wt. thermoplastic phase change material. The organic resin includes at least one of epoxy resin, alkyd resin, phenolic resin, acrylic resin, polyurethane, polyamide resin, bismaleimide resin and polyimide resin. The photothermal material includes at least one of inorganic semiconductor nanocrystals, carbon-based materials and conjugated high molecular polymers. The thermoplastic phase change material includes at least one of long-chain alkanes, fatty acids and fatty alcohols. USE - Used as a sunlight-driven self-healing paint. ADVANTAGE - The sunlight-driven self-healing paint: has excellent sunlight-driven self-healing effect, which can repair the defects of the organic coating multiple times under sunlight; and prolongs protective life of the organic coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing sunlight-driven self-healing coating comprising coating the self-healing coating on the surface of a base material.
