Abstract

Functionalized porous aromatic frameworks (PAFs) are excellent candidate materials for hybrid membrane fabrication. However, tailoring PAFs for membrane CO2 separation with desirable performance is still a challenge. Here, facile fabrication of functional hybrid alkylamine-modified PAF-1 containing membranes with high compatibility for efficient CO2/N2 separation is reported. The methylamino groups are installed on PAF-1 resulting in PAF-1-CH2NH2 that has a high surface area of over 1400 m2 g–1 and unique CO2 adsorption with CO2/N2 thermodynamic selectivity of over 1000. Amidation reaction is developed for PAF-1-CH2NH2 cross linking with cPIM-1 (carboxylic polymer of intrinsic microporosity), giving a homogenous compatible membrane of PAF-1-CH2NH2—cPIM-1 with outstanding CO2 permeability (≈10790 Barrer) and high CO2/N2 permselectivity (≈43). This membrane outperforms the counterparts derived from parent PAF-1 and phenylamine PAF-1 and possesses superior performance to other relevant membranes for CO2/N2 separation. Such a membrane can selectively and stably separate CO2 from N2 in a simulated flue gas mixture, demonstrating its huge potential in carbon capture.
