A comment on New carbon nanotube-metal hierarchical material is 10x darker than Vantablack.

It is stated to be an order of magnitude better across the broad spectrum than other broad absorbers.

I wonder if there are any narrow bands that it specifically excels at compared to existing materials, and how big the difference is.

This is the relevant graph I think:

They are potentially misleading by connecting the dots in that way. (The classic, it implies data where there is nothing.)

There is a graph right at the top of the abstract that shows the reflectance of this new material compared to Vantablack across a number of wavelengths.
