Here [0] is the paper in question, it has a chart that shows the reflection rate of this one at around 0.3 - 2%; the paper itself has the following quote for the competitors: > Far lower reflectance values have been achieved with materials containing aligned carbon nanotubes (CNT), for example a low-density CNT array (0.045%),[11] the coating Vantablack (0.035%)[7] and a CNT-metal foil (0.005%).[12] The current holder of the “record” for a low reflectivity material (<0.0002%) is an ion-track micro-textured polymer with anti-backscatter matrix.[13] So they're arguing that it's on-par with Vantablack but not the newer materials.
