Wow, this sounds pretty nice. I remember watching a MedCram video recently that pointed out that long wave IR light has anti-inflammatory properties and that modern IR blocking glass is actually depriving people of many of the beneficial effects of sunlight. If this could get people more IR, it could raise the bar for health across the board. Still, I have some concerns. It's a polymer nanomaterial, so it's probably fairly fragile. The "self cleaning" part is just that it's hydrophobic, which is nice but relies on the nanostructure. Again, probably susceptible to damage. The chemical itself, poly-dimethylsiloxane is pretty common but it appears that they're forming the nanostructures using a mould made via silicon lithography? That's not going to scale at all, nor does the coating seem durable enough for decades of outdoor use.
I only skimmed the paper so please correct me if I'm wrong but this is very far from production-ready.
- hackernewds 2y agoMind linking this video? It sounds dubious but I'm curious
- hcarvalhoalves 2y agoProbably, the video he mentions is about this: https://www.sciencedirect.com/science/article/pii/S1011134422002287 https://www.sciencedirect.com/science/article/pii/S101113442...
- dzhiurgis 2y agoAFAIK IR blocking film is fairly recent development. In NZ it's only past year when it became required for all new buildings (helps with reducing heating and cooling costs). Most glass blocks UV tho which makes some marketing shady.

- dokein 2y agoI can't comment on the manufacturing process, but in terms of durability -- would probably just put this in between two panes of glass in a double pane window?
- alan-hn 2y agoDoesn't that entirely defeat the purpose of this new glass letting in more light than new glass? Or would the outside panes be made of the new glass without the nano structure?
- sourdoughness 2y agoThe new material is an extremely thin film that sits on top of a traditional glass substrate: it doesn’t replace the window, and it doesn’t dim light or reduce the spectrum in the same way that frosted glass normally would.
