After the photochemical generation of carboxylates onto surfaces of several aromatic polymers, complexes based on zirconyl‐(IV)‐acetylacetonate are immobilized. These zirconium compounds tend to form strong bonds to carboxylates. Subsequently, zirconium modified surfaces are treated with solutions of a highly fluorinated lithium carboxylate yielding oil‐ and water‐repellent surfaces. It is shown that combined with excimer‐UV‐laser‐induced micro structuring, the treatments lead to super‐repellent surfaces showing contact angles of water up to 160°. © 2004 Wiley Periodicals, Inc.
