The graphene-based film is an interlayer separation film having a special mass transfer property. In this study, a novel TiO2 nanorod inserted graphene-based membrane on a CA (Cellulose Acetate) mat was fabricated by a vacuum filtration method for water treatment application. The intercalated TiO2 nanorods expanded the interlamellar spacing among the graphene sheets and thus advanced the separation efficiency of graphene-based membrane, which exhibited a flux several times higher than some commercial nanofiltration membranes and an extremely high rejection especially for dyes, for MB (99.3%), Rhb (99.4%), MO (99.3%), CR (99.6%).
