1. A wiper blade rubber for a windshield wiper, comprising a molded, vulcanizable elastomeric material, and a surface layer which is hydrophobic with a contact angle greater than 90° with respect to water, and has a surface structure with elevations and/or depressions from 1 to 100 μm wherein the surface layer is a foil on the elastomeric material, wherein the foil has an upper side and a lower side, wherein the lower side has an adhesive layer, and the upper side has the surface structure and is hydrophobic. 2. The wiper blade rubber as claimed in claim 1, characterized in that the foil comprises a material selected from the group consisting of crosslinked or partially crosslinked polyethylene, polyamide, polypropylene, and polytetrafluoroethylene. 3. The wiper blade rubber as claimed in claim 1, characterized in that the foil is applied by means of a carrier to which the foil adheres. 4. The wiper blade rubber as claimed in claim 1, wherein the surface structure comprises depressions with average height of less than 100 μm and separation from 1 to 100 μm. 5. The wiper blade rubber as claimed in claim 1, wherein the surface layer (3) has a contact angle greater than 120° with respect to water. 6. A windshield wiper blade, comprising a molded, vulcanizable elastomeric material, and a surface layer which is hydrophobic with a contact angle greater than 90° with respect to water, and has a surface structure with elevations and/or depressions from 1 to 100 μm wherein the surface layer is a foil on the elastomeric material, wherein the foil has an upper side and a lower side, wherein the lower side has an adhesive layer, and the upper side has the surface structure and is hydrophobic. 7. The wiper blade as claimed in claim 6, characterized in that the foil comprises a material selected from the group consisting of crosslinked or partially crosslinked polyethylene, polyamide, polypropylene, and polytetrafluoroethylene. 8. The wiper blade as claimed in claim 6, characterized in that the foil is applied by means of a carrier to which the foil adheres. 9. The wiper blade as claimed in claim 6, wherein the surface structure comprises depressions with average a height of less than 100 μm, and separation from 1 to 100 μm. 10. The wiper blade as claimed in claim 6, wherein the surface layer (3) has a contact angle greater than 120° with respect to water. 11. The wiper blade rubber as claimed in claim 1, wherein the foil consists essentially of crosslinked or partially crosslinked polyethylene. 12. The wiper blade rubber as claimed in claim 1, wherein the foil consists essentially of crosslinked or partially crosslinked polyamide. 13. The wiper blade rubber as claimed in claim 1, wherein the foil consists essentially of crosslinked or partially crosslinked polypropylene. 14. The wiper blade rubber as claimed in claim 1, wherein the foil consists essentially of crosslinked or partially crosslinked polytetrafluoroethylene.
