Abstract:Supercritical CO 2 expanded ethanol is used to induce a phase separation process for one-step preparation of porous skinless membranes from a modified poly(etheretherketone). The process takes the advantage of the flexibility of the procedure that is also timesaving and greener than traditional phase separation methods. Skin-less membranes with modular structures have been obtained, combining different processing parameters, including SC-expanded liquid composition, polymer concentration, temperature and press… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
