<br/>Idaho National Laboratory is developing polymer membranes designed to enrich oxygen from air to enable utilization of the nation’s coal supplies with controllable carbon emissions. Technology that will be aided by cheap membrane-derived enriched oxygen includes gasification systems. Polysulfone (PSF) is found to have suitable properties for gas separation membranes; however, their performance for oxygen separation would benefit from being increased. Within polymer science, applications of nanodiamonds (ND) are still considered reasonably novel. To improve PSF membrane performance, PSF-ND mixed-matrix membranes have been fabricated with the goal of enhancing oxygen permeability while maintaining selectivity. In this presentation, thermomechanical analysis, common behaviors, and observed trends in these PSF-ND mixed matrix membranes will be discussed.
