METHOD FOR PRODUCING A FILM HAVING MICROSCOPIC AND NANOMETRIC SURFACE STRUCTURES, AND ONE SUCH FILM

摘要

The invention relates to a method for structuring the surface of a film with microscopic and nanometric structures. The invention is characterised in that a film is used which comprises at least one surface provided with microchannels, said microchannels being communicating, at least in parts, and open on one side towards the film surface; a second film is combined with the film having a structured surface in such a way that the microchannels are covered in a liquid-tight or a gas-tight manner by said second film; and at least one liquid or gaseous medium is guided through the microchannels, said medium removing film material inside the microchannels, by means of chemical interaction, in order to create microstructures and/or nanostructures, and/or producing a coating pattern in the form of microscopic and nanometric structures.
