Method for Nano-Structuring Polmer Materials Using Pulsed Laser Radiation in an Inert Atmosphere

摘要

In a method for generating a surface having a solid polymeric material, which has surface structures with dimensions in the sub-micrometer range, the untreated surface, on which the structures are to be generated and which are accessible to laser radiation, is scanned once or multiple times using a pulsed laser beam in an inert gas atmosphere in such a way that adjacent light spots of the laser beam adjoin each other in a gapless manner or overlap and a certain range of a specified relation between process parameters is observed.
