Abstract:Polymers of intrinsic microporosity (PIMs) are attractive materials for gas adsorption due to their high surface area and interconnected microporosity. However, the low CO 2 affinity of PIM-1 results in only a small amount of physisorbed CO 2 , making the addition of higher affinity species, such as basic amines, a requirement for use in dilute CO 2 applications. This has been previously accomplished by trapping added amines in the polymer pores, with deleterious consequences for gas transport, regeneration en… 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.
