The present invention relates to novel (AB) block copolymers for use in coating surfaces to provide self-cleaning surfaces and capture/release materials wherein the copolymers comprises a first hydrophobic block (A) comprising a polymer selected from the group consisting of: a homopolymer of a fluorinated acrylate or methacrylate monomer (A1); a random, alternating, gradient or block copolymer, (A1A2) comprising: a fluorinated acrylate or methacrylate monomer (A1); and a non-fluorinated acrylate or methacrylate monomer (A2); a random, alternating, gradient or block copolymer, (A1A2) comprising: a fluorinated acrylate or methacrylate monomer (A1) and a silyl acrylate or methacrylate monomer (A3); and a random, alternating, gradient or block copolymer, (A1A2A3) comprising: a silyl acrylate or methacrylate monomer (A1), a fluorinated acrylate or methacrylate monomer (A2) and a non-fluorinated acrylate or methacrylate monomer (A3); and a second hydrophilic block (B) comprising a non-fluorinated acrylate or methacrylate monomer.

La présente invention concerne de nouveaux copolymères en blocs (AB) destinés à être utilisés pour le revêtement de surfaces pour produire des surfaces autonettoyantes et capter/libérer des matières, lesdits copolymères comprenant un premier bloc hydrophobe (A) comprenant un polymère sélectionné parmi le groupe comprenant : un homopolymère d'un monomère de type acrylate ou méthacrylate fluoré (A1); un copolymère statistique, alterné, à gradient ou en blocs (A1A2) comprenant un monomère de type acrylate ou méthacrylate fluoré (A1) et un monomère de type acrylate ou méthacrylate non fluoré (A2); un copolymère statistique, alterné, à gradient ou en blocs (A1A2) comprenant un monomère de type acrylate ou méthacrylate fluoré (A1) et un monomère de type acrylate ou méthacrylate de silyle (A3); et un copolymère statistique, alterné, à gradient ou en blocs (A1A2A3) comprenant un monomère de type acrylate ou méthacrylate de silyle (A1), un monomère de type acrylate ou méthacrylate fluoré (A2) et un monomère de type acrylate ou méthacrylate non fluoré (A3); et un second bloc hydrophile (B) comprenant un monomère de type acrylate ou méthacrylate non fluoré.
