    摘要: The invention relates to sheet extrudates with surfaces which have self-cleaning properties, and also to a simple process for producing these self-cleaning surfaces. The process of the invention is very simple, since it can make use of existing equipment. Sheet extrudates are usually smoothed by means of rolls. The process of the invention makes use of these rolls by applying microparticles to these rolls. The particles are impressed into the surface of the extrudate and thus transferred thereto during smoothing of the extrudates. The process of the invention provides access to self-cleaning surfaces which comprise particles with a fissured structure, without any need to apply an additional emboss layer or a foreign-material carrier layer to the moldings. Extrudates of the invention may have the shape of a film or sheet, for example.

    摘要: The invention relates to devices produced by injection molding for storing and/or handling liquids, which can be emptied without residues, and also to a simple process for producing such devices. Liquids are frequently taken up and distributed in a defined manner using pipette tips, syringes, ampoules or similar devices. However, for technical reasons, the pipette tips available on the market today cannot pipette the smallest volumes desired without contact, i.e. provide unaided and complete release of the liquid to be pipetted from the pipette tip. Equally, it is currently impossible to completely empty storage vessels. The devices according to the invention overcome this problem by the surfaces which come into contact with the liquid being provided with self-cleaning properties. This makes it possible to take up and distribute liquids without residue in a simple manner and to completely empty storage vessels. The process according to the invention is very simple since it can use existing equipment. Customarily, injection-molded parts are produced by means of injection molds into which the material is injected. The process according to the invention uses this process by applying microparticles to the injection mold before the actual injection molding, these being transferred to the injection-molded part on injection molding by being impressed into the surface of the injection-molded part.

    摘要: A self-cleaning surface which has an artificial, at least partially hydrophobic, surface structure containing elevations and depressions, which comprises an at least partially hydrophobic surface formed from structure-forming particles of hydrophobic fumed silica having elevations and depressions ranging in dimensions of 1 to 1000 nm and the particles themselves having an average size of less than 50 μm adhered to the surface by way of a viscous, curable carrier material selected from the group consisting of polyurethane, polyurethane acrylates, silicone acrylates and singly and/or multiply unsaturated (meth)acrylates applied to the surface, which is sufficient to bond the structure forming particles without substantial wetting of the particles by the carrier material while retaining the fissured structure of elevations and depressions of the structure-forming particles in the nanometer range.
