Abstract
Modified plastic surfaces with perfluoropolymers are provided, whereby plastic surfaces that are intended for use under tribological conditions have substantially improved assembly properties and/or sliding friction properties and exhibit a very low degree of wear. Accordingly, modified plastic surfaces with perfluoropolymers are provided in which modified perfluoropolymer (micro)powders are present at the surface of plastics that comprise olefinically unsaturated double bonds at least at the surface such that the modified perfluoropolymer (micro)powders are chemically covalently bonded via a radical coupling of the olefinically unsaturated double bonds with perfluoropolymer (peroxy) radicals of the modified perfluoropolymer (micro)powders after a reactive conversion under mechanical stress at room temperature.
