METHOD FOR NANO-STUCTURING POLMER MATERIALS USING PULSED LASER RADIATION IN A REACTIVE ATMOSPHERE

摘要

In a method for producing a surface with a solid polymeric material which has surface structures having dimensions in the sub-micrometer range, the untreated surface on which the structures are to be produced and which is accessible to laser irradiation is scanned with a pulsed laser beam one or more times in a reactive gas atmosphere in such a manner that adjacent light spots of the laser beam have unbroken abutment or overlap with one another, and a certain range of a predetermined relation between method parameters is met, whereby the surface is chemically modified.
