When light strikes Vantablack, instead of bouncing off, it becomes trapped and continually deflected amongst the tubes, absorbed, and eventually dissipated as heat. [24] CVD Vantablack was an improvement over similar substances developed at the time. Vantablack absorbs up to 99.965% of visible light and can be created at 400 °C (752 °F).
Oxidants can not only remove or prevent amorphous carbon growth, but may also etch into graphite layers when used at higher than favorable concentrations. Hata et al. reported millimeter-scale vertically aligned 2.5 mm long SWCNTs using the water assisted ethylene CVD process with Fe/Al or aluminum oxide multilayers on Si wafers. [17]

A fact from Vantablack appeared on Wikipedia's Main Page in the Did you know column on 20 July 2014 (check views). The text of the entry was as follows: The text of the entry was as follows: Did you know ... that Vantablack , a material made from carbon nanotubes , is the blackest substance known?
As a result, infrared light of a wavelength longer than a few micrometers penetrates through the dark layer and has much higher reflectivity. The reported spectral dependence increases from about 1% at 3 μm to 50% at 20 μm. [3] In 2009, a competitor to the super black material, Vantablack, was developed based on carbon nanotubes. It has a ...
The security muttered, "God damn Blacker gang", and the phrase stuck. Blacker students began signing GDBG or γδβγ on all their pranks. Blacker has also been referred to as the house of fucking geniuses [12] and the inscription HOFG can be found throughout the tunnels along with γδβγ. In the 1960s the house slogan was "Blacker House for ...

Ultra-black is one of the darkest shades of the color black.An ultra-black substance is defined as reflecting less than 0.5% of the light that hits its surface. [1] This color is part of the natural coloration of some species of birds-of-paradise, butterflies, and fishes, and ultra-black components are used in telescopes, cameras, and solar panels to improve the efficiency of light capture.
