The membranes containing facilitated transport groups for Carbon dioxide had been prepared by immobilizing PAMAM ( Polyamidoamine) (Generations 0,1,2,3,4) dendrimer into the polymeric membranes. The dendrimer incorporated membranes were prepared by the phase inversion method. The permeation abilities of the membranes for pure CO 2 and binary mixture of CO 2 /N 2 were calculated. The effects of feed gas pressure on the permeability of the membranes were studied. The results of the permeation experiments showed that PAMAM dendrimer (Generation 4) composite membrane possessed a better CO 2 permeability and selectivity over N 2 than the any other membranes composite with other generations of dendrimer (Generations 0,1,2,3).
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.
