Molecular separation using poly (styrene-co-maleic anhydride) grafted to Γ-alumina
Abstract
<p>Here, we report the covalent coupling of poly (styrene-co-maleic anhydride) onto γ-alumina to develop high-performance organic solvent nanofiltration (OSN) membranes. A high molecular weight (M<sub>w</sub>) alternating copolymer of maleic anhydride (MA) and styrene (St) was synthesized and directly grafted to the γ-alumina membrane, while commercially available low M<sub>w</sub> random copolymers of St and MA were also investigated. We show that solute rejection and membrane permeability strongly depend on the nature of the applied copolymer. In particular, the M<sub>w</sub> of the copolymer applied is potentially the key for improving the membrane performance. When a high M<sub>w</sub> copolymer was applied, the grafted layer covered the surface of the membrane. This results in membranes with significantly improved rejection, while maintaining a high permeability. In contrast, we observed pore grafting by applying low M<sub>w</sub> copolymers, which resulted in membranes with slightly higher rejection and dramatically lower permeability compared to unmodified membrane. The best results were obtained by grafting γ-alumina with a high M<sub>w</sub> alternating copolymer. These membranes showed a solute rejection of 98% for Sudan Black B (457 g mol<sup>−1</sup>) in toluene, while the permeability remained high at 2.9 L m<sup>−2</sup> h<sup>−1</sup> bar<sup>−1</sup>.</p>
