Anti-icing coatings


With the aid of plasma technology, the Fraunhofer IGB has developed an anti-icing coating for polymeric surfaces. Water-repellent micro- and nanostructured coatings are applied to polymer foils made of impact-resistant and shockproof polyurethane (PU), where the anti-ice finish reduces the ice’s adhesion by over 90 percent. Optimization of various process parameters has made it possible to produce ultra-thin coatings only a few nanometers thick, these coatings repel water from the surface. The nanostructured foil can be glued onto the rotor blades, wings of airplanes, solar panels, and power lines.
