Researchers at China’s Nipsea Group, which operates in Singapore, say they have developed an ultra-black coating that absorbs an average of 99.9% of visible light. The finish is so dark that a painted object can appear flat, almost like a void or a “hole in reality,” rather than a normal three-dimensional car body.
The company says the paint is durable enough for automotive standards and is aimed at China’s growing appetite for luxury cars in deep black, a color associated with prestige and power. In a striking visual effect, a car coated with the material can seem like a shadow in the middle of the road, with no visible curves or design details.
The science behind the effect combines regular carbon black pigment with carbon nanotubes. Through a physical process the researchers call pi interaction, the black particles arrange along the nanotubes into a “point connection” structure that creates a microscopic landscape of peaks and valleys. When light hits the surface, it is trapped, repeatedly scattered internally, and then absorbed almost completely, turning into heat.
Unlike earlier ultra-black coatings that were easily damaged by touch, the new version reportedly passed durability tests, including 14 days at 95% humidity and 10 days submerged in water without visible damage. It can also be applied with conventional spray methods, making mass production possible. Critics are already asking how a car like this would be seen at night, and noting that such a light-absorbing surface would likely heat up significantly in strong sun.
