Surface with an Anti-Adhesion Microstructure and Method for Producing Same
摘要:
The invention relates to a surface comprising a microstructure that reduces adhesion and to a method for producing said microstructure. Microstructures of this type that reduce adhesion are known and are used, for example, to configure self-cleaning surfaces that us the Lotus effect. According to the invention, the surface is produced electrochemically by means of reverse pulse plating, the known microstructure being first produced and a nanostructure that is overlaid on the microstructure is produced at the same time or in a subsequent step. To achieve this for example, the pulse length of the current pulse that is used during the reverse pulse plating lies in the millisecond range and has a pulse length ratio greater than 1:3. The microstructure that has been produced, consisting of peaks and troughs is then overlaid with peaks and troughs of a smaller size order belonging to the nanostructure.
