New Hydrogel Coating Revolutionizes Limescale Management

Researchers develop a limescale-repellent hydrogel coating, significantly enhancing efficiency in thermal power plants and domestic appliances.

A collaborative effort by ETH Zurich and UC Berkeley leads to the creation of a hydrogel coating that prevents limescale adhesion.
The innovative coating, inspired by shark skin, uses microscopically small ridges to reduce limescale contact and facilitate its removal.
Tests reveal up to 98% of limescale crystals can be removed, offering a more eco-friendly alternative to traditional descaling methods.
The technology promises substantial energy savings by improving efficiency in thermal power plants and extending the lifespan of domestic appliances.
The research, published in Science Advances, is made freely available for further development, bypassing the patent process.
