But the issue related to these two approaches is that in one case, if a surface likes to attract water and be hydrophilic, it also attracts everything else: dust, dirt, etc. On the other hand, with the hydrophobic surfaces, it's very challenging to scale these up. As a result, we started to look at alternative ideas, such as how we can employ the energy of light to prevent this effect.
But the challenge was actually to develop a coating that selectively absorbs sunlight. How can it retain its transparency, yet absorb the infrared part of the light, which in fact makes up 50% of solar energy?When gold is deposited, individual particles first settle on the surface. The more gold you deposit, the more continuous your film becomes.
Iwan: I remember exactly the first day we tested it outside. You measure all that stuff in the lab on the setup and technically the physics holds and it should work, but I was pretty amazed when I saw it actually perform. Hence, it was quite astonishing to me, especially when we tested it in the mountains. After the experiments, in the evening when I checked the level of solar radiation during the day, I was baffled by how low the radiation actually was.
Are there any applications beyond glass anti-fogging that this technology could be adapted to in the future? Iwan: Of course, sunglasses are a potential market that we foresee. We are also looking at car headlights, windshields, and any other application where you can localize heat on the nanoscale .
