CONTAINER WITH STRUCTURED FLUID REPELLENT AND FLUID WETTABLE PARTIAL REGIONS OF THE INNER SURFACES

摘要

The invention relates to containers whose inner surface has liquid-repellent and wettable subregions, where a) the liquid-repellent subregions have structuring by elevations with an average height of from 50 nm to 10 mum and with an average separation of from 50 nm to 10 mum, and have a surface energy of less than 35 mN/m for the unstructured material, and b) the wettable subregions have no elevations.
