This paper considers the fabrication of multiwalled carbon nanotubes (MWCNTs)/polyethersulfone (PES)mixed matrix hollow fiber membranes and the effect of COOH functionalized MWCNTs on the morphology andhydrogen permeation of membranes. Addition of MWCNTs into polymer matrix causes to formation of finger likemacrovoids in the membranes structure and also increases their hydrogen permeance. This phenomenon results fromlowering the packing capability of PES polymer matrix after incorporation of nano size fillers.
