The Fraunhofer FEP, together with the Fraunhofer IOF and industrial partners, has developed a method for making polymer films anti-reflective in an efficient roll-to-roll process. By using plasma-etching in vacuum equipment anti-reflective properties can be applied to polymer films in a more efficient way than with any other currently available process. The process is ideal for very thin polymer films, where the application of a multilayer anti-reflective layer system would adversely affect the film flexibility. Even curved substrates can be uniformly treated using this process.
The Fraunhofer FEP uses dual magnetron systems, which are normally used for coating, as plasma sources for a process which is stable over several hours in order to effectively render polymer films anti-reflective
