Preparation and characterization of nanocomposite membrane based on single-walled carbon nanotubes for gas separation

Mixed matrix membranes (MMM) comprised of multi-walled carbon nanotubes (SWCNTs) inside Poly (amide-6-b-ethylene oxide)(PEBAX) matrix were fabricated and characterized for gas separation performance. Effects of SWCNTs loading on the gas permeation properties of the MMM were investigated by varying the SWCNTs loading in the PEBAX matrix from 1–5wt%. The fabricated SWCNTs/ PEBAX MMM were characterized by scanning electron microscopy (SEM), Stress–strain and pure gas permeation test. gas permeation measurement showed that MMM embedded with 3 wt% SWCNTs possessed better performances in terms of permeability and selectivity in comparison to pure Pebax-1657 membrane
