Description

Muhammad Imran Jamil and co-authors coat surfaces with candle soot to let hulls and rotors slip through water on a cushion of air. Superhydrophobic coatings cut drag by holding such an air layer, the plastron, but pressure and chemistry collapse it in cold seas, and the benefit drowns. Their 2026 paper embeds soot nanoparticles in an elastic binder, making a porous coat whose air pockets can heal.

The soot's web of nanopores grips the air layer hard. A coated copper ball carried a gas cavity nearly fifteen times the bare ball's volume on hitting water, and its drag coefficient fell near zero. In swirling flow between cylinders, a coated rotor cut drag by sixty percent, and flow resistance dropped about fifteen percent in rheology tests. The authors pitch soot, of all things, as a marine technology.
