depending on its degree and spectrum of "blackness" (and cost?), it
could have many applications. Did it retain its properties as the
oxide grew?

I haven't the equipment or the time to measure the degree and spectrum of the
"blackness". Suffice it to say, you can still see a very dim spot if you shine
a variety of lasers of different wavelengths onto the surface. Naturally, the
substrate, PET film, heats up and burns when you do this.

I no longer have the instruments to measure the absorptance and
reflectance of materials; but, most optical instruments have black
paint on the inside walls. A new source of very black films or sheets
could be a useful addition because, over the years, the paint turns
grey.

As you are no doubt aware, even black paint made to coat the interior of
optical instruments has the problem of a quite high glancing angle reflectance.
My nanoporous aluminum film has a very low glancing
They might come up with $6M for thermal control inside satellites.
