Dresden scientists have developed a self-cleaning metallic surface. A project team of the Technische Universität Dresden and the Fraunhofer Institute for Material and Beam Technology IWS structured an aluminum plate with a laser process in such a way that water droplets can roll at its surface and thus remove dirt particles – completely without chemical cleaning agents or additional effort. The scientific evidence of the self-cleaning effect has been published in the journal “Applied Surface Science”.
For several years, scientists at TU Dresden and Fraunhofer IWS have been developing functionalized surfaces by means of laser-based manufacturing processes.
