Novel method for producing superhydrophobic or superhydrophilic surface

摘要

The present invention relates to a surface texturing method that provides a surface having superhydrophobic, superoleophobic, superhydrophilic, or superlipophilic properties. This method comprises i) texturing the surface (by deposition of different sized nanoparticles); ii) curing the textured surface (with a curing agent); and iii) perfluorinated ( It consists of an optional step that modifies the surface properties with hydrophobic molecules. This method is particularly suitable for treating transparent and / or heat sensitive materials and surfaces. Specifically, none of the process steps use temperatures higher than 100 ° C. Thus, the method of the present invention is particularly suitable for treating transparent surfaces made of non-inorganic materials such as polycarbonate, for example, since it does not affect surface transparency or optical properties.
