Nano-ZnO is of special characteristics for its dimension effect. The surface treatment methods of nano-ZnO were introduced, which include electrochemistry, physical modification and chemical modification. The preparation methods of nano-coating including solgel-gel, in-situ polymerization, physicalblend and insert-layer, etc., and the characteristics of nano-ZnO such as ultraviolet shielding, enhanced-intensity, antibiosis-deodorization, antiflaming, etc. were described. The mechanisms of special characteristics were analyzed. Nano-ZnO used as pigment filler improves the coatings performance obviously and gives the coating′s novel functions. The prospect of nano-ZnO applications in coatings was presented.
