Abstract: The disclosure relates to an amphiphilic block copolymer comprising a first block consisting of a polymeric hydrophilic domain, wherein the polymeric hydrophilic domain consists of a polyglycerol; an optional second block consisting of a hydrophobic domain and a first linker domain, wherein the second block is covalently bound to the first block via the first linker domain, an optional third block consisting of a catechol domain and a second linker domain, wherein the third block is covalently bound to the first block via the second linker domain; and a fourth block consisting of a crosslinking domain and a third linker domain, wherein the fourth block is covalently bound to the first block via the third linker domain, wherein the crosslinking domain comprises a reactive residue enabling a crosslinking between individual molecules of the amphiphilic block copolymer.

Abstract: An article, comprising a substrate and a polymer film attached to the substrate is provided, the polymer film comprising a first layer of a first polymer functionalized by a first functionalization compound covalently bound to said first polymer and bearing at least one catecholic group being present on a surface of the first layer. The polymer film is a layered film, a top layer of which is formed by the first layer, the layered film comprising at least one further layer of at least one further polymer functionalized by a further functionalization compound covalently bound to said further polymer and bearing at least one catecholic group being present on a surface of the at least one further layer, wherein an average ratio of catecholic groups per polymer molecule is equal to or less than 1 in case of the first polymer and greater than 1 in case of the further polymer.
