Abstract:
Coated material, comprising: a porous polymer-substrate and a coating material applied to at least one surface of the substrate, which material comprises condensates of at least one compound A of the general formula RaMZb (a=0-3; b=1-4; a+b=3-4), in which R is a nonhydrolyzable organic group, and at least one compound B of the general formula Râ€²xMZy (x=1-3; y=1-3; x+y=3-4), in which Râ€² is a nonhydrolyzable organic group, and at least one Râ€² contains a perfluoropolyether structure separated from M by at least two atoms, in which M is an element chosen from groups IIIA-VA or groups IIB-IVB of the periodic system and Z is a hydrolyzable organic group, and in which at least one R is not identical to at least one Râ€².
