Black Breakthrough

Another technology innovation aided by nanotechnology, researchers have announced the development of a new material that is so black it absorbs more than 99.9 percent of light.

Made from tiny tubes of carbon standing on end, this material is almost 30 times darker than a carbon substance used by the U.S. National Institute of Standards and Technology as the current benchmark of blackness.

The substance has a total reflective index of 0.045 percent — which is more than three times darker than the nickel-phosphorous alloy that now holds the record as the world’s darkest material. (Basic black paint, by comparison, has a reflective index of 5 percent to 10 percent.)
