METHOD FOR THE FABRICATION OF PERIODIC STRUCTURES ON POLYMERS USING PLASMA PROCESSES

摘要

This invention presents a method for the fabrication of periodic nanostructures on polymeric surfaces by means of plasma processing, which method comprises the following steps: (i) provision of a homogeneous organic polymer (such as PMMA, or PET, or PEEK, or PS, or PE, or COC) or inorganic polymer (such as PDMS or ORMOCER); (ii) exposure of the polymer to an etching plasma such as oxygen (O2) or sulphur hexafluoride (SF6) or a mixture of oxygen (O2) and sulphur hexafluoride (SF6), or mixtures of etching gases with inert gases such as any Noble gas (Ar, He, Ne, Xe).
