"Unveiling the Power of Ultrablack Coatings in Space Telescopes"

Researchers from the University of Shanghai for Science and Technology and the Chinese Academy of Sciences have developed an ultrablack film coating for aerospace-grade magnesium alloys using atomic layer deposition (ALD) that can absorb 99.3% of light, significantly improving the performance of space telescopes and optical hardware. The coating, made of alternating layers of aluminum-doped titanium carbide and silicon nitride, can be applied to curved surfaces and withstand adverse environmental conditions, making it a promising advancement for space exploration and astronomy.
