All have achievements: coating is a promising field of nanomaterials

Coating is an old and young research and application field It is an interdisciplinary field of materials, chemistry, physics, etc it is a promising field of nanomaterials and nanotechnology As the chief scientist of nanotechnology research, Professor Youwei of Nanjing University told reporters this view It is said that the development direction of coatings is environmental protection, functional, intelligent and composite The application of nano materials in coatings reflects a major aspect of the development direction of coatings At present, the world is facing the most severe and complex environmental problems Nano materials used to enhance the performance of coatings can improve the environment The advantages of nano coating are summarized in 5 aspects First, with the decrease of particles, the covering power of light increases Second, the whiteness is enhanced The whiteness of nanometer titanium dioxide and zinc oxide is 10 times higher than that of ordinary titanium dioxide and zinc oxide Third, the use of paint is reduced, which can be reduced by 1 / 3 in general Fourth, the adhesion is strong, and the hardness and finish of the film are increased Fifth, nano titanium dioxide and zinc oxide have the functions of self-cleaning and sterilization
