OBTAINING GRAPHENE-BASED MEMBRANES

Graphenic-based PEI/PVP membranes were obtained by Non-solvent Induced Phase Separation Process (NIPS) method using graphene-related carbons (GRC) obtained from rice husk through a top-down approach. A further tailoring of GRC through a treatment with sulfuric acid was also explored. The GRC-based membranes displayed the presence of fully developed macro-pores and a substructure of smallest micropores.
