Turning Surface Flaws into Cooling Superpowers | Science News
Scientists in Korea have invented a revolutionary coating that supercharges heat transfer by turning microscopic surface imperfections into performance boosters. By engineering tiny bumps on a polymer film, they accelerate condensation and help water droplets shed quickly—keeping surfaces primed for constant heat exchange. Tested on copper tubes used in industrial condensers, the coating outperforms plain copper by 5.5x and standard hydrophobic coatings by over 50%. This breakthrough redefines “flaws” as functional assets, promising major efficiency gains in energy systems, desalination, and…
