Description

Technical field[0001]The present invention relates to a paint, in particular, the present invention relates to an easy-to-clean anti-fouling self-repairing nano-coating with intelligent energy supply. The present invention also relates to a preparation method of the paint, and belongs to the technical field of paint.Background technique[0002]Intelligent self-repairing material (Intelligent Self-repairing) was first proposed by the U.S. military. It is applied to the surface treatment of military equipment. Its core is through material and energy supply, and at the same time imitating the principle of biological damage healing to make composite materials Internal or external damage can heal by itself, and intelligent self-healing coatings mainly include external self-healing materials and intrinsic self-healing materials. Foreign aid-type self-healing materials mainly include micro / nano capsule-filled self-healing coating micro, nano-container-filled self-healing coating, shape memor...
