Abstract
Disclosed is a process for manufacturing a membrane from a, amphiphilic block copolymer including a hydrophilic block and a hydrophobic block including functions capable of forming a bond with the hydrophilic block in a bath 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 and the support and the immobilisation of a first layer of the copolymer on the surface of the support; followed by adding water to the bath, so as to give rise to the self-assembly of a second layer of copolymer on the first layer.
