Like some of the best scientific discoveries, this record-setting black stuff was discovered by accident.

就像部分最佳科学发现一样，这种创纪录的黑色物质也是偶然发现的。

The researchers were looking at ways to grow CNTs on electrically conductive materials like aluminium, and it was during these experiments that they noticed the blackness of the materials they were growing on specially treated aluminium foil.

研究人员在寻找在导电材料（例如铝）上植入碳纳米管的方法，正是在这项实验中，他们注意到他们在特殊处理的铝箔上植入的这种材料的黑度。

"I remember noticing how black it was before growing carbon nanotubes on it, and then after growth, it looked even darker," says mechanical engineer Kehang Cui, from Shanghai Jiao Tong University in China. "So I thought I should measure the optical reflectance of the sample."

来自中国上海交通大学的机械工程师崔克航表示：“我记得我注意过在植入碳纳米管之前它的黑度，而在植入之后，它看起来更黑了，所以我认为我应该测一下样品的光反射率。”

That's when the ultra-powerful light absorption properties were recorded – from every possible angle, the material soaked up virtually all the light directed at it.

这种超强光吸收特性就是在这时被记录下来的——从每一个可能的角度来看，这种材料几乎都吸收了所有射向它的光。
