“…the PDMS membrane without adding Sepiolite, the selectivity was 2.65 for O 2 /N 2 and 5.75 for CO 2 /CH 4 . These values are comparable to those reported in the literature under similar conditions [35][36][37].…”

“…The synthesized PIS membranes were used for measuring the permeabilities of single gases such as O 2 , N 2 , and CO 2 using constant pressure/variable volume method [21][22][23]. The feed pressure was varied from 1 bar to 5 bar and the permeate pressure was maintained at atmospheric pressure.…”
“…In our previous work, we have studied the structure-gas transport properties of cationic and anionic membranes, their solubility and diffusivity with the cationic and anionic groups were discussed [30,31]. In this paper, we have reported the gas transport properties of PDMS-PU membranes containing various wt.% of hard segment content and with different hard segment structures.…”
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.
