In Situ Permeability Measurements and Impedance Spectroscopy for Assessing Separation Performance and Nano-Structure in CO₂-Selective Polymeric Mixed-Matrix Membrane

A hollow fiber-supported polymeric mixed-matrix membrane, consisting of a Pebax-1657 matrix and graphene nanoplatelet (GNP) fillers as the selective layer, was tested for CO₂/CH₄ gas separation at transmembrane pressures up to 30 bar(a). Using a custom, novel, membrane module,...
