2. In the application of paint Nano-materials because of its special nature and structure of the surface with general access to the excellent performance materials show a strong vitality. Surface coating technology is the focus of attention of the world. Surface coating of nano-materials provided a good opportunity to make great material may be functional. Using conventional coating techniques, adding nano-materials, nano-composite system available coating function, the leap modified traditional functional coatings. According to the structure of coatings and coating purposes can be divided into functional coatings. Coating matrix is coated to improve some of nature and modification; Functional coating matrix is not available given the performance of the functions which is not traditional coating. A superhard coatings, wear coatings, anti-oxidation, heat, fire-retardant coating, corrosion resistance and decorative coatings; Functional coatings are absorbing light, light reflectivity and the selective absorption of light optical coatings, electrical, insulation, electrical characteristics of semiconductor coating, oxygen sensitive, humidity, the gas-sensitive coating properties. The addition of nano-materials in the paint, to further enhance its defense capabilities, achieving protection against ultraviolet radiation, resistance and resistance against atmospheric degradation, color, the application can play in the health sterilization cleaning supplies role. Nano coating used on the plate, its optical properties can be used to achieve storage of solar energy, energy conservation purposes. In building materials such as glass, paint fit into the nano materials can reduce the transmission of light and heat transfer effects have insulation and fire effects. Japan's Matsushita has developed a good electrostatic shielding nanocomposite coating, which is applied to the iron oxide nanoparticles, such as titanium dioxide and zinc oxide. These characteristics of nanometer semiconductor oxide particles at room temperature with the conventional oxides high conductivity properties, which will play the role of electrostatic shielding, and oxide nanoparticles of different colors, it could also compound controlled electrostatic shielding paint colors, silica overcome electrostatic shielding paint only a single color monotone. Nano-materials, not only with the size and color change, with color effects with the angle. The decorative spray in the car industry, in addition to Nano TiO2 cars, cars Metallic Topcoat that will have a rich and mysterious color coating effects, so that the traditional Automotive Top Take Shape. UV radiation is a nano - silica material. In addition nano - silica coating, the coating will aging properties, smoothness and intensity increased manifold. Nano coating is the application stage, coating technology will bring a new technological revolution, it will promote the research, development and application of composite materials.
