▎ 摘　　要

NOVELTY - High-performance antibacterial and antiviral environmental protection coating comprises substrate, antibacterial material and solvent, where the antibacterial material and the substrate are dissolved in the solvent, the antibacterial material comprises a coating layer and a first antibacterial composition, the coating layer contains a first photoionized spiropyran terminal group, the high-performance antibacterial and antiviral environmental protection coating is switched between the first state, the second state and the third state, and when in the first state, the coating layer covers the periphery of the first antibacterial composition, and the antibacterial material and the matrix are distributed in the solvent; when in the second state. USE - Used as high-performance antibacterial and antiviral environmental protection coating. ADVANTAGE - The coating has high-performance antibacterial, antiviral and environmental protection properties. DETAILED DESCRIPTION - High-performance antibacterial and antiviral environmental protection coating comprises substrate, antibacterial material and solvent, where the antibacterial material and the substrate are dissolved in the solvent, the antibacterial material comprises a coating layer and a first antibacterial composition, the coating layer contains a first photoionized spiropyran terminal group, the high-performance antibacterial and antiviral environmental protection coating is switched between the first state, the second state and the third state, and when in the first state, the coating layer covers the periphery of the first antibacterial composition, and the antibacterial material and the matrix are distributed in the solvent; when in the second state, the coating layer covers the outer periphery of the first antibacterial composition, and the antibacterial material moves toward the light source to the outermost side of the formed paint layer; in the third state, the covering layer is open, exposing the first antimicrobial composition. An INDEPENDENT CLAIM is also included for coating method of high-performance antibacterial and antiviral environmental protection coating, comprising (i) before coating, mixing substrate, antibacterial material and solvent together to obtain mixed solution, (ii) when coating, coating the mixed solution on the carrier, (iii) make the antibacterial material move towards the light source to the outermost side of the formed paint layer through the first preset condition, and (iv) opening covering layer according to the second preset condition, so that the first antibacterial composition is exposed.
