摘要

Mixed matrix membranes (MMMs) were fabricated by incorporating synthesized titanium dioxide (TiO ₂ ) nanoparticles into polyether block amide (PEBA) matrix to fabricate TiO ₂ /PBEA MMMs for CO ₂ /N ₂ separation. The mesoporous channels of TiO ₂ increased the density of active sites with high accessibility and also facilitate the diffusion of CO ₂ in the gas separation process. Furthermore, amine groups are grafted onto the TiO ₂ fillers via one step reaction with dopamine (DA) and polyethyleneimine (PEI). The modified TiO ₂ fillers with abundant amine groups are conductive to transfer CO ₂ owing to the reversible reaction occurred between CO ₂ and amine groups. The effects of TiO ₂ loading, DA/PEI modification on the morphology and CO ₂ /N ₂ separation performance of the resulting TiO ₂ /PBEA MMMs were systematically studied. The results showed that the MMMs filled with 3 wt% DA-PEI-TiO ₂ synthesized with DA/PEI mass ratio of 1/1 and PEI molecular weight of 1800 exhibited optimal separation performance with CO ₂ permeability of 67 Barrer and CO ₂ /N ₂ selectivity of 101, surpassing the 2008 Robeson upper-bound.
