Attempts to create absolutely black material were made by different groups of scientists with different percentage of success. Researchers from Rennselaer of the Polytechnic Institute in 2007 created material consisting of vertical carbon tubes (VACNT), the darkest material known to science. Due to the ability to absorb 99.97% of the world. VACNT is of great importance for the study of solar energy, for example, it can be used to increase the efficiency of solar panels.
RPI researchers were not the only ones who tried to create absolutely black material. A group of scientists from NASA has developed its own model of material made of carbon nanotubes, which has the percentage of light absorption 99.5%.
The usual surface of the product, painted with black paint and covered with graphite, absorbs most of the visible spectrum of light, but reflects from 5 to 10% in space. Although scientists have not yet reached the goal, creating a material with an indicator of reflection equal to zero, the dark absorbing material developed in RPI is the best model and can be used to convert solar energy and pyroelectric detectors. As a material absorbing light, it can also be used in the production of refrigerators, which gives a huge savings in energy resources.
But often in the offset you do not need black color and preference is given to warmer and brighter colors. Often in this case, they resort to decorative plaster of Set silk. It gives the effect of beautiful overflow similar to “wet silk”.
