Engineering a molecular-sieving architecture on poly(ionic liquid)-functionalized UiO-66-NH<sub>2</sub> membranes toward CO<sub>2</sub>/N<sub>2</sub> separation
A PIL-functionalized PET supported UiO-66-NH<sub>2</sub> membrane (PET/UiO-66-NH<sub>2</sub>@PIL) was synthesized through photoinduced crosslinking of 1-vinyl-3-butylimidazolium tetrafluoroborate ([VBIM][BF<sub>4</sub>]), establishing a coordination-induced hierarchical architecture. This engineered membrane synergistically combines the CO<sub>2</sub>-philic sites of PIL molecular-sieving domains with the size-exclusion effect of UiO-66-NH<sub>2</sub> nanocages, achieving exceptional CO<sub>2</sub> permeance of 162 GPU and CO<sub>2</sub>/N<sub>2</sub> selectivity up to 68.3.
