SURFACE-STRUCTURED POLYURETHANE SUBSTRATES AND METHODS FOR PRODUCING THE SAME

摘要

A method for producing a polymeric surface-structured substrate includes: (a) preparing a first precursor substrate that is nanostructured on at least one surface with inorganic nanoparticles, (b) coating a hardenable substrate material for a second substrate different from the first precursor substrate material onto the nanostructured surface of the precursor substrate, wherein the hardenable substrate material includes cross-linkable monomeric, oligomeric or polymeric starting components for producing a polymeric substrate, (c) hardening the hardenable substrate material to obtain a polymeric substrate, and (d) separating the precursor substrate from the polymeric substrate as a result of which a polymeric substrate nanostructured with nanoparticles and including a polyurethane is obtained.
