A photo-initiated microcapsule with poly(urea-formaldehyde) shell was synthesized through in situ polymerization, in which aliphatic polyurethane acrylate and photointiator were used as photo-initiated healing agents. The surface morphology and structure of microcapsules were characterized by FT-IR and SEM. The size distribution and thermal stability of microcapsule were characterized by laser particle sizer and thermal gravimetric analyzer(TGA). The results show that microcapsules successfully encapsulate core materials and own a thermal stable temperature of 226 ℃. The optimized agitation rate is 500 r/min with a mean diameter of 101.9 μm and an encapsulation percent of 51.46%. The optical microscope (OM) images show the crack in microcapsule-embedded coating is successfully healed under UV irradiation for 20 min. This work provides a green and efficient self-healing process.
