In this paper，a self-healing coating was proposed based on the shape memorybehavior of thermosetting resin and the fluidity of thermoplastic liquid rubber，and carbon black was used for photothermal healing. A photo-thermal responsive self-healing coatingbased on liquid rubber was prepared by epoxy resin matrix，thermoplastic liquid nitrile butadiene rubber（CTBN）restorative and photo-thermal filler carbon black（CB）. The coating was characterized by infrared thermal imager，thermogravimetric analyzer（TG）， scanning electron microscope（SEM）， and optical microscope. The influence of CB filler on the photo-thermal property of the coating was investigated. The influence of healing agent on the coatingmorphology，properties and self-healing behavior was also studied. The results showed thatunder near-infrared light irradiation，absorption rate of the coating would be improved by bits of CB. Thus the photo-thermal property was greatly improved. CTBN as a thermoplastic restorative was dispersed in epoxy resin at microscale，then flowing and filling the crack. Thephoto-thermal property of the coating was increased with increase of CTBN. It was showed thatexcellent self-healing performance with 0. 08% CB，7. 69% CTBN under the light power density of 0. 8 W/cm². Meanwhile，the corrosion resistance could be restored efficiently after crack healing.
