  Abstract

The composite membranes were made by grafting using supercritical carbon dioxide (scCO2) impregnation and polymerization procedures. The membranes were synthesized by changing amount of monomer. The polypropylene frafted polystyrene sulfonic acid (PP-g-pssa) membranes were characterized with various methods. The morpholohy and structure of PP-g-pssa membranes were analyzed with scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). As amount of monomer was increased, ion conductivity, cell performance was increased and methanol permeability was decreased. However PP-g-pssa membranes with 1.5g monomer and over had similar values of methanol permeability, ion conductivity and cell performance.
