Abstract:Novel dual modified PU membranes were prepared by β-cyclodextrin (CD) crosslinking and carbon fiber (CF) filling. The structures, thermal stabilities, morphologies and surface properties were characterized by FTIR, TGA, SEM, XRD and contact angle. PV performances were investigated for the mixture of phenol and water. The dual modified membranes showed not only higher permeability, but also better selectivity than PU membranes. At 80 • C for the 0.5 wt% phenol aqueous solution, the total flux of PU was 6.59 kg … 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.
