Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.
And unlike many materials that stay stuck in the purgatory of development stage, this innovation is already being scaled. Dewpoint Innovations is currently developing a water-based paint formulation ...
The vast majority of absorbent materials will lose their ability to retain water as temperatures rise. This is why our skin starts to sweat and why plants dry out in the heat. Even materials that are ...
