This project belongs to the field of materials science and special functional materials. Starting from the control of the shape, structure and size of nanomaterials, and based on the principle of self-assembly, it has developed a series of functional multi-component nanomaterial composite coating technologies. Through industry-university-research cooperation, many innovative results have been achieved in technology development, formula design and production process optimization. The application of the developed coating technology to the processing of existing products improves the performance of the product and increases the added value of technology of the product, injects new impetus into the development of the company, and greatly enhances the company's competitiveness in the industry. It has mainly developed the following three industrialized nano-composite coating technologies: 1. Glass anti-reflection technology;2. Photocatalyst composite nano-coating technology;3. Metal anti-corrosion and wear-resistant composite nano-coating technology. This project has applied for 17 national invention patents and utility model patents, 9 of which have been authorized.

1. Glass anti-reflection technology: Different from traditional vacuum evaporation glass anti-reflection technology, we self-assemble and compound metal-organic framework nanomaterials, nano silicon dioxide and nano titanium dioxide to develop glass anti-reflection composite nano-coating technology. Organic assembly of nanomaterials with different functions not only achieves anti-reflection of the glass, but also gives the glass some other characteristics such as self-cleaning. The technology has simple process and low cost. Based on this technology, a series of production equipment have been independently developed, realizing the industrial production of anti-reflection lamp glass and anti-reflection photovoltaic glass. The light transmission performance of the anti-reflection lamp glass and anti-reflection photovoltaic glass produced has reached the international leading level, and has good weather resistance and self-cleaning properties. For example, the light transmission of anti-reflection lamp glass has reached 97.5%, which is used as a light source cover plate., can increase the luminous efficiency by more than 7%; anti-reflection photovoltaic glass is used in solar crystal silicon cells, increasing the power generation by more than 2%. The "3.2 Plain White Self-Cleaning High Light Efficiency Anti-reflection Lamp Glass" developed based on this technology has been identified as a key new product in Jiangsu Province by the Jiangsu Provincial Economic and Information Technology Commission, filling the gap in this type of product in China;"Self-Cleaning High Light Efficiency Anti-reflection Lamp Glass" and "High transmittance photovoltaic tempered self-cleaning coated glass" have been recognized as high-tech products by the Jiangsu Provincial Department of Science and Technology.
2. Photocatalyst composite nano coating technology: Through self-assembly and compounding of nano materials such as titanium dioxide, hydroxyapatite, and silicon dioxide, a photocatalyst water-based coating technology with efficient visible light photocatalytic properties has been developed. Through the doping of titanium dioxide and the synergistic effect of hydroxyapatite, efficient photocatalytic activity in the visible light range is achieved. The coating material produced by this technology has good stability, has strong photodecomposition activity on formaldehyde, benzene compounds and TVOC, and can effectively kill bacteria and inhibit viruses. It has been identified as a key new product of Jiangsu Province by the Economic and Information Technology Commission of Jiangsu Province, and its performance has reached the domestic leading level. In addition, the "MS-II energy-saving photocatalyst fluorescent lamp" developed by us in conjunction with glass anti-reflection technology has been recognized as a high-tech product by the Jiangsu Province Department of Science and Technology.
3. Metal anti-corrosion and wear-resistant composite nano-coating technology: First, a rapid, high-yield and low-cost liquid-phase ultrasonic lift-off technology was developed to produce graphene and sheet-like molybdenum disulfide nanomaterials, and then graphene and molybdenum disulfide nanosheets were self-assembled and compounded with silica nanosols, metal oxide nanosols, etc., and metal anti-corrosion and wear-resistant coating technology was developed. The pencil hardness of the film formed by this technology on the metal surface is greater than 7H. It has good hydrophobicity and long-term stability, strong acid and alkali resistance, and the maximum temperature resistance can reach 600℃. It can be used for metal corrosion protection in harsh environments.
