摘要

通过光诱导交联1-乙烯基-3-丁基咪唑四氟硼酸盐（[VBIM][BF4]），合成了一种il功能化PET负载的UiO-66-NH2膜（PET/UiO-66-NH2@PIL），建立了配位诱导的层次化结构。该工程膜协同结合了PIL分子筛选域的亲CO₂位点和UiO-66-NH2纳米笼的尺寸排斥效应，实现了162 GPU的CO₂渗透率和高达68.3的CO₂/N₂选择性。

Engineering a molecular-sieving architecture on poly(ionic liquid)-functionalized UiO-66-NH2 membranes toward CO2/N2 separation†

A PIL-functionalized PET supported UiO-66-NH2 membrane (PET/UiO-66-NH2@PIL) was synthesized through photoinduced crosslinking of 1-vinyl-3-butylimidazolium tetrafluoroborate ([VBIM][BF4]), establishing a coordination-induced hierarchical architecture. This engineered membrane synergistically combines the CO2-philic sites of PIL molecular-sieving domains with the size-exclusion effect of UiO-66-NH2 nanocages, achieving exceptional CO2 permeance of 162 GPU and CO2/N2 selectivity up to 68.3.
