Scientists turn tiny “defects” into a 5.5x heat transfer boosthttps://www.sciencedaily.com/releases/2026/08/260823014940.htm
Scientists have developed an ultrathin coating that could dramatically improve how efficiently heat is transferred during condensation. By turning tiny polymer structures once considered “defects” into places where water droplets can form, then helping those droplets detach quickly, the new surface keeps exposing fresh areas for condensation. In tests on copper tubes, it transferred heat up to 5.5 times more effectively than conventional copper and more than 50% better than a standard water-repelling coating.
