Abstract
Ultrathin unobstructed gas transport channels through the membrane selective layer are constructed in mixed matrix membranes (MMMs) by using gravity-induced interface self-assembly of poly(vinylamine) and polymer-modified MIL-101(Cr). For CO2 /N2 (15/85 by volume) mixed gas, the MMMs achieve a high CO2 permeance of 823 gas permeation units and CO2 /N2 selectivity of 242 at 0.5 MPa. Based on economic analyses, a two-stage membrane process can achieve gas separation and economic targets.Entities:
