Super black wide-band light absorbing nano coating (Super black wide-band light absorbing nano coating) can absorb almost all the light incident on the surface of the material, including ultraviolet light, visible light, near-infrared light, and light in the middle and far-infrared bands. There are no reflections. The absorption rate of all incident light on the surface of the material reaches more than 96%, the highest is more than 99%, the total hemispherical reflectivity is as low as 1%, and the radiation rate is close to 1, which is close to a black hole. The preparation of ultra-black light-absorbing films is very technically difficult, and has always been a hot research direction in the laboratory and industry in the fields of nanomaterials science, surface engineering, optoelectronics, etc.
Black surface treatment technology, there are traditional methods such as black paint spraying, electroplating and anodizing. The light absorption rate of these technologies is difficult to exceed 90%, especially in the infrared band, the absorption rate is as low as less than 20%, which cannot meet the market needs at all. In addition, these processes also have problems such as too thick film layer, rough and loose, poor adhesion, unstable high and low temperature environment, release of harmful organic substances, and the production of a large number of pollutants in the preparation process. Therefore, it is necessary to replace these backward processes with more advanced technologies. The general trend. In this context, the ultra-black broadband light-absorbing coating based on vacuum nanotechnology has made great progress and has begun to be applied in industry.
Ultra-black light-absorbing and extinction nano-films have broad application prospects. Due to the ultra-high absorption rate, it can absorb visible light and infrared light almost perfectly, avoid all kinds of useless reflected light, eliminate harmful stray light, and absorb all light energy. These characteristics can be used in precision optical instruments and optical parts, lidar, lens imaging, Infrared imaging, infrared sensing, machine vision and detection, visual recognition, medical imaging optical instruments, photovoltaic solar energy, photoelectric photothermal systems, heat dissipation management, heating materials, as well as appearance decoration and aesthetic appreciation are widely used in products, which can greatly Improve product quality, increase product attractiveness, and develop new product directions. Through the application of these products, ultra-black light-absorbing coatings will be widely used in the following fields: optical lenses and imaging, automotive lidar, machine vision, precision optical instruments, medical instruments, LED displays, aerospace, military industry, solar energy , notebook computers, mobile phones, smart wear, watch jewelry, ultra-black glass and other fields.
Application 1. Lidar
The internal light source of lidar is generally near-infrared light of 905nm and 1500nm. The extinction treatment of the inner wall of the optical path has a great impact on the imaging quality of the product. The ordinary extinction treatment technology cannot meet the technical requirements of the product. At present, the ultra-black full light absorption coating of Shenzhen Jingshi Nanotechnology Co., Ltd. has been applied to the products of several well-known lidar manufacturers, which fully meet the technical requirements of the products.
Application 2. Optical Lens
In terms of optical systems, lenses and imaging, at present, the lens rings, spacers, etc. of major brands, as well as the inner wall of the optical path, have begun to use more and more super black light-absorbing matting coatings to reduce imaging ghosts, improve imaging quality, and increase Appearance attractive. Especially at present, the camera lens modules of most high-end products of major mobile phone manufacturers have adopted ultra-black nano-coating technology. However, the current mainstream process is anti-reflection optical multi-layer coating. This process has obvious shortcomings. Because it uses the principle of optical interference, the colorful reflection is very obvious, which greatly affects the imaging quality and also affects the appearance of the product. Infrared light has almost no absorption capacity, so it is completely useless for imaging with lenses that require infrared absorption. In comparison, Jingshi Nano's latest ultra-black full-band light-absorbing and extinction nano-coating has great advantages. It can not only enhance the appearance attractiveness, but also significantly improve the imaging quality when applied to various lenses and optical imaging systems.
Application three, LED display
LED display technology has developed rapidly in recent years and has been widely used. Ultra-black light-absorbing coating accessories have also begun to be applied to LED displays. The application of ultra-black coating can completely replace the traditional black paint process, and greatly improve the display contrast, picture sharpness and imaging quality, bringing a better appreciation experience to the audience.
Application 4. Machine Vision and Inspection
The primary basis of machine vision and detection is to obtain accurate data of the imaged object. If there is too much interference from stray light and useless light, it will inevitably lead to unclear imaging and inaccurate data, thus making machine judgment and detection fail. The ultra-black light-absorbing extinction coating is prepared on each relevant part, which enables the optical system of the machine to accurately capture the image of the observation or test object, eliminates various interferences, and obtains accurate data, thus perfectly solving the problem of identification and detection.
Industry progress
At present, only companies such as Israel and the United Kingdom can provide industrialized ultra-black light-absorbing coatings. The ultra-black coating of Israel Acktar Company is a special structural material prepared based on vacuum plating technology, with a thickness of 5-10 microns and a total hemispherical reflectivity of 1-5%. It is currently the product with the highest market share. The VantaBlack series of ultra-black products launched by British Surrey Nano Systems are based on vertically aligned carbon nanotubes, and are available in coating products and coatings. In recent years, the Japanese company Musou has launched several generations of ultra-black coatings, claiming that the absorption rate has increased from 95% to 99.4%, but it is mainly used in the visible light band, and the binding force and durability are relatively poor.
This field in China has always been relatively backward. Except for some research results of the Institute of Chinese Academy of Sciences, the industry has always been blank, resulting in related industries relying on imports for a long time, and the high cost cannot be reduced. Recently, Shenzhen Jingshi Nanotechnology Co., Ltd. has achieved a technological breakthrough in ultra-black coating, which has changed this situation. The company's ultra-black broadband full-absorption nano-coating has begun industrial application, and has completed the process from laboratory to commercial mass production. The products' visible light and infrared light absorption performance and other indicators have reached the international advanced level. Substitute, fill the blank of domestic related industries, with important technical, economic and social value.
Jingshi Nanotechnology Co., Ltd. has accumulated more than ten years of R&D and production technology in the fields of vacuum plasma surface treatment and nanomaterial technology, and has completely independent intellectual property rights in the ultra-black full light-absorbing coating technology. Jingshi ultra-black coating is a completely green and environmentally friendly high-tech process. It can be prepared on the surface of metal, ceramic, glass and plastic materials, on three-dimensional parts, and on flexible films. Due to cost considerations and user requirements for different grades of products, Jingshi has recently launched two grades of ultra-black light absorption coating products, namely two grades of coating services with absorption rates of 96% and 99%. Customers can choose according to different applications.
