Abstract (en)
[origin: WO2014056479A2] The invention relates to a method for producing a surface comprising a solid polymer material, said surface having surface structures with measurements in the sub-micro range. According to the invention, the non-treated surface on which the structures are to be produced and which can be reached by the laser radiation, is scanned once or several times using pulsed laser radiation in a reactive gas atmosphere in such a manner that adjacent light flecks of the laser radiation are next to each other without an interspace or overlap and a defined range of a predetermined relation between method parameters is maintained, siad surfaces being therefor chemically modified.
