Synergistically Crosslinked PIM-NORB-TB Membranes for Energy-Efficient Hydrocarbon Separation
Abstract: Developing energy-efficient alternatives to conventional thermal separations is crucial to lowering the environmental impact of the petrochemical industry. Membrane-based processes offer a sustainable route, but practical deployment requires materials combining high selectivity with solvent resistance. This project investigates PIM-NORB-TB membranes featuring a synergistic dual crosslinking strategy that integrates covalent (TMC) and coordination (Fe ) linkages. The resulting asymmetric architecture a thin, selective top layer over a microporous support delivers enhanced robustness and molecular sieving performance. Using neutron reflectivity in hydrogenated, deuterated, and contrast-matched solvents (methanol, toluene, and heptane), we will quantify solvent-induced swelling, interfacial morphology, and layer thickness in three membrane variants: uncrosslinked, TMC-crosslinked, and TMC+Fe crosslinked. These insights will establish a direct link between crosslinking chemistry, nanoscale organisation, and separation efficiency, guiding the design of next-generation membranes for energy-efficient hydrocarbon separations.
