Description
Jeongsu Pyeon and co-authors coat surfaces with a plant-based film that melts ice using sunlight in a 2023 paper. The film mixes cellulose nanocrystals, a renewable material from plants, with gold nanorods that turn light into heat. Laying the rods down in an even, aligned pattern is the hard part.
Their method exploits two quick physical effects as a drop dries: rapid self-dewetting and self-assembly during evaporation. Tuning the ink and coating settings balances the two and avoids coffee-ring stains. The result is a uniform film with ring patterns in four aligned quadrants and strong light-to-heat action. The coated surface stayed above freezing while the base below it was subcooled, showing anti-icing power.
