Plastic That Both Attracts and Repels Water
posted May 22, 05:10 PM by Puffo
Imagine a surface that can both attract and repel water like magic. Water droplets roll like small balls over the surface.
Scientists have reported numerous applications of water-attracting (superhydrophilic) and water-repelling (superhydrophobic) surfaces, including fog-free eyeglasses and windshields, and self-cleaning cloth and glass. Now a group of researchers in MIT’s materials science and engineering department has combined those opposing characteristics on a single surface, by using a simple and versatile fabrication process.
