Vantablack is supposedly the darkest substance ever made, and this is because it absorbs up to 99.965% of radiation in the visible spectrum of light. It’s made out of a forest of vertical tubes that are grown on a substrate using a modified version of a chemical process called chemical vapor deposition.
It can only be created at temperatures that are higher than 400C, so it can only be “grown” on substances that are capable of withstanding very high temperatures. Another interesting property that the material has is its ability to trap visible light and bounce it around among the nanotubes that make up the substance. This light eventually becomes absorbed and is dissipated into heat.
Vantablack’s unique properties have resulted in it being used in satellites and telescopes to eliminate stray light, and artists, designers, and other creatives are also falling over themselves to get their hands on it. Here’s a closer look at this wondrous material:
