The wettability of microfiltration membranes has been examined. The analytical method used is an application of the Wilhelmy plate procedure. The use of a new sample holder especially designed for this purpose enables the surface analysis of polymer films even if they present two physically different faces. The evolution of wettability properties during the membrane production process has been determined for nuclear microfiltration membranes obtained from poly(ethylene terephthalate) (PET) and polycarbonate (PC). A grafting procedure in solution, which can be applied to PET- and PC-based materials, enhances the wetting properties of membranes and make them similar to those reached by poly(vinylpyrrolidinone) adsorption.
