Japanese Scientists Make Blackest Material On the Planet
Research team has created a sheet of CNTs that absorbs almost all wavelength of light
This novel material would be of great value for solar panels or for heat collection from space. As a comparison, the blackest paints and coatings currently available absorb between 80-95% of all light. The vertically aligned single-walled CNTs is the closest thing to a black body, a theoretical material that absorbs light of all wavelengths. When viewed by the eye, the material looks flat, yet is really a sheet comprised of sparse and imperfectly-aligned single-walled CNTs.
