Abstract (en)

[origin: WO2018127656A1] The invention relates to a process for manufacturing a membrane (16) from an amphiphilic block copolymer (20) comprising a hydrophilic block (21) and a hydrophobic block (22). This process comprises successive steps of immersing a support (10) comprising functions capable of forming a bond with the hydrophilic block (21) in a bath (11) containing the copolymer in solution in an apolar organic solvent, for a sufficient time to enable the formation of non-covalent bonds between the hydrophilic block (21) and the support (10) and the immobilization of a first layer of the copolymer on the surface of the support; followed by adding (13) water to the bath (11), so as to give rise to the self-assembly of a second layer of copolymer on the first layer.
