How does it compare to the other super-black materials, the Vantablacks and the like?
- HPsquared 2y agoProbably less carcinogenic.
- Cthulhu_ 2y agoI dunno, it looks like they're creating carbon nanostructures; while wood carbon / soot seems fairly benign, I still wouldn't want to breathe it.
- cenamus 2y agoAnd tar/pitch is definitely carcinogenic
- tetris11 2y agothat's what a lot people with wood burners used to say...
- throwanem 2y agoYeah, but everybody chain-smoked from age 3 in those days, so it's not easy to tell.
- Cthulhu_ 2y agoHere [0] is the paper in question, it has a chart that shows the reflection rate of this one at around 0.3 - 2%; the paper itself has the following quote for the competitors: > Far lower reflectance values have been achieved with materials containing aligned carbon nanotubes (CNT), for example a low-density CNT array (0.045%),[11] the coating Vantablack (0.035%)[7] and a CNT-metal foil (0.005%).[12] The current holder of the “record” for a low reflectivity material (<0.0002%) is an ion-track micro-textured polymer with anti-backscatter matrix.[13] So they're arguing that it's on-par with Vantablack but not the newer materials.

- shibbidybop 2y agoFrom your numbers Vantablack is 0.035%, whereas the new process bottoms out at 0.3%. So they’re within 10x of Vantablack, but not on the same level.
- Alifatisk 2y agoIf my understanding is correct, Nxylon is lighter than Vantablack (in terms of weight) but reflects slightly more light. This means that it is less effective than Vantablack at absorbing light.
