Article source: National Nanoscience Center? On April 9, 2021, my country successfully launched the Trial Six 03 satellite into the space at the Taiyuan Satellite Launch Center, and the satellite successfully entered the scheduled orbit.
The surface of the satellite optical system light shield adopts the nanocomposite ultra-black coating material developed by the National Nanoscience Center to suppress stray light such as sunlight and earth light, which will greatly improve the satellite optical system's ability to detect dim targets.
? The dim signal detection capability and accuracy of the space satellite optical system are seriously affected by stray light.
The light absorption rate of the super black material can be increased by 1% to increase its ability to suppress stray light by orders of magnitude.
Based on the intrinsic light absorption of carbon nanomaterials and the multi-reflection and light absorption synergistic mechanism of the micro-nano composite structure, the engineered large-area nanocomposite ultra-black coating material developed by the National Nanoscience Center has an absorption rate of up to 99.
6% in the ultraviolet-visible-near-infrared range.
Exceeds the performance of similar products in the United States, France, and Israel currently in service in the aerospace field, and the absorbance and technological maturity are superior to those of NASA’s nanotechnology roadmap; tested by an independent third party, it fully meets the requirements of wide-angle absorption, high-frequency vibration, and high-speed Various indicators and performances for satellite launch and extreme space environment applications such as impact, quality loss, ultraviolet aging, and thermal cycling.
The successful launch of Test 6 03 is the first time that my country's satellite optical system uses super-black material light-shielding technology.
Nanocomposite ultra-black coating materials have broad application prospects in dim target detection, interstellar navigation, infrared stealth and other fields.
