The graphene oxide was synthesized through a modified Hummers' method, and then attached to beta-SiAlON through dip coating. The morphology of the surface modified membrane was verified by SEM. The existence of graphene oxide on the beta-SiAlON membrane surface was confirmed by TEM and Raman spectrum. The pore size characterization indicated that the surface modification slightly decreased the membrane pore size. The surface wetting behaviors were investigated by measuring the water and underwater contact angles. The separation performance was investigated by separating hexane-in-water emulsion. The impacts of surface modification on permeation flux, rejection rate, and stability of the membrane were investigated.
