POLYMERS FOR MAKING SUPERHYDROPHOBIC SURFACES

摘要

The present disclosure relates to a process for making a comb-like polymer comprising the following steps of reacting an epoxy-functionalized monomer with a nucleophile comprising a C8-C20-alkyl group or halogen substituted C8-C20-alkyl group in the presence of an aqueous medium and polymerizing the reaction product. The comb-like polymer has functional groups on its backbone and long hydrophobic side chains. It can even be produced as a shell on a submicron sphere according to an alternative process according to the invention. The polymers obtainable by the inventive process can be polymerized with polyurethane prepolymers to achieve coating surfaces that show superhydrophobicity (see Fig.). Such coatings can have numerous applications especially in the aircraft industry for paints used on the airplane wings, because they avoid water droplet building.
