First report on synthesis and characterization of graphene-based membrane (POLITO, M6)

Graphene oxide will be considered for the fabrication of ionically selective membrane Commercial GO powder will be used to fabricate labscale GO membrane by vacuum filtration of GObased water dispersion At the same time alternative membrane fabrication process will be investigated screen printing calendaring doctorblade spin coating as preliminary step for subsequent scaling up The GO membranes will be functionalized in order to obtain a selfpolarization of the membrane residual positive and negative charge for anion and cationexchange membranes respectively The GO membranes will be characterized both by SEM Raman XPS and TEM
