Harbin Institute Of Technology: Overcoming The Technical Bottleneck Of Preparing Ultrablack Coating At Room Temperature

?

Harbin Institute of Technology (Harbin Institute of Technology) announced that Professor Wu Xiaohong of the school of chemical engineering and chemistry of the university has made an important breakthrough in the field of ultra black coating technology, overcome the technical bottleneck of ultra black coating preparation at room temperature, and obtain a highly stable ultra black coating with remarkable Lambert characteristics.

According to the test of the third-party authority, the wide spectrum absorption of the coating is as high as 99.8%, the total scattering integral is as low as 1.5% when the light is 80 ° incident, and the condensable volatile matter is 0.00%. The coating can fully meet the requirements of various substrates, complex surfaces, ultra large area implementation process and space extreme environment applications, and its performance and technical maturity are better than those of similar products in service at home and abroad.

According to reports, the ultra black coating can absorb almost all the light on it, and has a wide range of applications. Most precision optical instruments need ultra black coating to shield optical interference and improve signal-to-noise ratio and detection ability.

Over the past 20 years, Professor Wu Xiaohong's team has "customized" a series of ultra black coatings to meet the service environment for working conditions, and has delivered thousands of products, such as sunshades, light barriers, diaphragm tubes, calibration blackbody and other products, which have effectively improved the in orbit detection capability and positioning accuracy of China's spacecraft optical loads, It provides the necessary conditions for the high performance and stable operation of the load in the whole life cycle.
