We all know Vantablack, the darkest substance that has so far only been created in laboratories. Meanwhile, her successor, 10 times darker, has just been created at Cambridge at MIT. See her in action.
Vantablack can be proud of absorbing as much as 99.965% of sunlight, while the new substance from the United States absorbs as much as 99.995% of light best tips online. The material is made of vertically arranged carbon nanotubes. The microscopic fibers under the microscope look like a forest.
The aluminum foil on which the material is based has been placed in salt water so that the oxide layer, which is an insulator blocking electrical and thermal conductivity, can be removed. The film was then transferred to an anaerobic environment to prevent reoxidation, and was finally placed in an oven where the cultivation of carbon nanotubes began in a process called chemical vapor deposition.
By removing the oxide layer, scientists were able to grow carbon nanotubes on aluminum at significantly lower temperatures than in any other case by about 100 degrees Celsius. An interesting fact is that the combination of CNT on aluminum has significantly improved the thermal and electrical properties of the material, e.g. compared to Vantablack.
New, darkest material in the world. It was created at MIT and absorbs 99.995% of light best tips online. Fig. MYTH.
In experiments, MIT engineers used a 16.78-carat yellow natural diamond, estimated to be worth $ 2 million. It was covered with new, ultra-black CNT material. The effect is amazing. A beautiful, shiny gem has become a black and flat emptiness.
MIT scientists have not yet said the last word. They are now going to improve their technique. The result is to get even blacker material. Their purpose is to commercialize their invention. First of all, they think of all sorts of artists who want to use the darkest substance in the world in their phenomenal works. They also admit that it will be used in projects for masking military installations or lowering reflections on various objects.
