Abstract
A method for the treatment of a substrate; the substrate comprises hollow fibre membranes, each of which has a side wall, comprising a base material, and an inner lumen, which is delimited by the side wall; the base material comprises a polysulfone or a derivative thereof; the substrate is placed in contact with graphene oxide in the presence of a liquid so as to obtain an intermediate compound, from which the liquid is at least partially removed and which is thermally treated so that the graphene oxide is at least partially fixed to the substrate and a treated material is obtained comprising treated fibres.
