Abstract: The present invention pertains to composition suitable for manufacturing membranes based on vinylidene fluoride (VDF) polymers, to porous membranes thereof, to methods for their manufacture and to uses thereof, especially for the filtration of water phases. Said composition comprising vinylidene fluoride (VDF) polymers and polymer additives comprising zwitterionic moieties delivers outstanding hydrophilization performances of manufactured membranes.

Abstract: The present disclosure relates to the use of a composition for reducing or preventing colloids adhesion and/or fouling on a substrate, the composition comprising a copolymer having repeating units derived from one or more zwitterionic monomers and repeating units derived from one or more phosphorous acid monomers.

Abstract: The present invention relates to a process for grafting polymers onto a metallic material, comprising the following steps: a) oxidation of the surface of the metallic material, resulting in an oxidized metallic material; b) grafting of a polymer at the surface of said oxidized metallic material by radical polymerization of a monomer, said radical polymerization comprising an initiation step and a propagation step, said initiation step being carried out by UV irradiation with a UV source diffusing a power at the surface of the material of greater than 72 mW·cm?2, said UV irradiation being carried out for a duration greater than 15 minutes and less than 180 minutes, said process resulting in a grafted metallic material. The present invention also relates to the materials capable of being obtained by this process, and applications of the latter, in particular as articular or dental implants.
