Is "graphene" vaporware? I've been hearing it hyped up for over ten years but it isn't actually a proper usable technology yet, as far as I can tell. Just endless press releases about making it in increasingly unlikely ways in the lab.

Too bad the graphene in the masks makes them dangerous for people to wear[1]… [1]: https://www.cbc.ca/news/canada/montreal/masks-early-pulmonary-toxicity-quebec-schools-daycares-1.5966387 https://www.cbc.ca/news/canada/montreal/masks-early-pulmonar...
- toomanybeersies 5y agoThat article makes me wonder if carbon nanomaterials are shaping up to be the next asbestos.
- shawnz 5y agoCarbon nanotubes in fact have similar pathology to asbestos. I don't think that specific issue applies to graphene though.
- iancmceachern 5y agoYes. I've tried to use it several times in designs and it doesn't really have many practical uses. Companies are trying to use it in "head spreader" films, pads , etc. The issue is that it's only one atom thick, it has amazing thermal conductivity through the film, but very low cross section of material to do the thermal transfer because it's so thin. It has thermal conductivity of an order of magnitude less in Z, so stacking it doesn't buy anything. It has some limited use in some very specific applications, but it's not terribly useful.
