Carbon nanotubes, essentially sheets of carbon atoms rolled into microscopic tubes, are exceptional light absorbers. The problem is that they are notoriously difficult to keep evenly distributed in a liquid coating mixture; they tend to clump, separate, and settle over time. To solve this, the team used a high-energy milling process to grind the carbon black and carbon nanotubes together in water along with dispersing agents. An accelerated stability test put the mixture through centrifuge forces more than 2,000 times the pull of gravity over seven hours, with only minimal separation, a strong indicator of shelf-stable industrial viability.
Because carbon black and carbon nanotubes share a chemical property that causes them to attract each other, the carbon black particles lined up along the nanotubes like beads strung on a wire rather than mixing randomly. Researchers describe this as a “connecting-the-dots” structure.
This arrangement creates a tiny, irregular surface texture on the coating, a landscape of microscopic peaks and valleys. When light hits this surface, it bounces around inside those valleys rather than reflecting back out, getting absorbed repeatedly, similar to soundproofing foam in a studio. Researchers call this “structural absorption,” and it’s the key mechanism that pushes the coating past the limits of conventional carbon black paint.
To measure how black a coating actually is, the automotive industry uses two numerical scales, “jetness” and “blackness,” where higher numbers mean a darker, more visually intense color. Standard carbon black coatings have essentially maxed out what’s achievable with that approach alone. The new coating posted meaningfully higher scores on both scales than the conventional formula tested alongside it...
Average reflectance across the visible light spectrum came in at approximately 0.08%. For context, Vantablack reflects about 0.04% of light, while common carbon-based coating materials typically reflect 1.5% to 4%.

The soulless democRATs / DemoKKKrats will no doubt complain that something is trying to be darker than they are.
Thank God they didn’t try to make a racist whiter-than-white paint. Black is cool.
I can think of uses for that; but it seems dangerous in regular vehicles.
What is the deal with all the greyscale paint jobs? Some people around here are even painting their houses like that.
Appears to be useful mostly for painting vehicles a black color that luxury car buyers will purchase more readily. Effect: You can’t see them, especially at night, so more wrecks?
If it absorbs RADAR I want it!............
I’m going to paint my 1967 GTO with PPG brand code 9000, that is the blackest black currently on the market. I’m repainting it the original color. I own two black cars, what was I thinking?!
Interesting that this is being reported and the Chinese are the innovators.
I mean if we were working on this it would be for primarily military applications and - no matter how far along we are - it would be classified and no one would know, especially not some t-shirt guy posting anonymously on FreeRepublic...
If only Ad Reinhart were alive today . . . “Ultimate Painting #2135”.
You know the saying, “Once you go black, you never come back” and “the darker the berry, the sweeter the juice”...
LOL...
“ Some people around here are even painting their houses like that.”
I also noticed people building new houses with black roofs and walls.
For the love of god people it’s Texas and it gets very hot here. Black paint/finishes absorb heat are it will damaged anything attached to it or under it.
For centuries people who live in a desert paint anything with outside exposure white. These new designers seem to be infected with a serious case of dumbassery!!
And the moment it gets dirty it sets off my OCD like every other dark colored car and I have to clean it until I see my face in it!
When people are happy you see bright peppy colors.
Grey and bleak has been the norm in houses and cars for the past 15 or so years.
Cars started to go back to color about a year ago. Houses will take a little longer.
I think it's calculated dumbing down all over the US: you can only have things beautiful if you're rich.
🤣
Assuming you don’t have a front plate, I bet this would absorb LiDAR from coppers.
I have a flat black car and was pulled over with the accusation of have a laser scrambling. No, just non reflective black.
I have one. I call it the Batmobile.
