NASA engineers have recently developed a new material that can achieve an absorption rate of up to 98% to 99% of ultraviolet, visible light, infrared and far-infrared band light. Its absorption rate is higher than that of other materials. 10 to 100 times. The material is a thin coating composed of hollow and multi-walled carbon nanotubes. The small gaps between the nanotubes can effectively absorb background light and prevent its reflection, thereby preventing background light from interfering with the light that scientists need to observe the target. . Since only a very small part of the light can be reflected, this material appears black to the naked eye or to a machine, and the darker the black, the higher its absorption rate of light. Once put into use, this material will greatly improve the performance of the detector and help scientists effectively observe weak celestial bodies in the universe.
