Perfluorosulfonate ionomer membranes for separation of petrochemical mixtures

Fine Morphology of Proton-Conducting Ionomers

“…“High-Tech” Materials: Perfluorinated Ionomers. Perfluorosulfonated ionomers are widely used as membranes in liquid and gas separation, − water electrolysis, − electro-organic synthesis, − catalysis, − electrochemical synthesis of chlorine and alkali, − nanoparticle synthesis, , and protective clothing. , In the past decade, these ionomers became the proton-conducting membrane materials for low-temperature fuel cells (polymer electrolyte fuel cells (PEFC)) , Almost all leading car manufacturers are involved in research and development of PEFC, and some, like General Motors/Opel, DaimlerChrysler, Ford, and Toyota, are close to the production of sample parties of PEFC-driven vehicles.…”

Development of new ionomer blend membranes, their characterization, and their application in the perstractive separation of alkenes from alkene-alkane mixtures. II. Electrical and facilitated transport properties

“…Pentene fluxes through the membranes were four times higher than those through commercial perfluorosulfonated ionomer (PSI) membranes 12 and 38 times higher than those through previously reported PSU membranes. 10 Separation factors were 13 times higher than with the PSI membranes and 5 times higher than with the initial PSU membranes.…”

“…12 Peristaltic pumps supplied constant flow of the feed solution through the upper compartment and the sweep solution through the lower compartment. Pentene-pentane was used as feed mixture, and hexane was used as the sweep solution.…”

Solid-state NMR investigations of a perfluorinated ionomer: Nafion

“…Besides the major applications in fuel cells and electrochemistry, Nafion also witnesses much more wide applications in different areas. Nafion can be used as a support material for the photoelectrochemical utilization of solar energy, 58,59 as a solid polymeric electrolyte for some photoelectrochromic 60 and electrochromic applications, 61,62 as a membrane for separation gaseous alkane from liquid alkene, 63,64 for pervaporation of methanol, 65 " 68 as a polymeric electrolyte in water electrolysis, 69 " 72 in electro-organic synthesis, 73 " 77 catalysis, 67 ' 68 ' 78 electrochemical synthesis of chloride and alkali metals, 67 ' 79 ' 80 as a template for nanoparticle synthesis, 81 ' 82 and in protective clothing. 70 ' 83 Further applications of Nafion include design of sensors for oxygen, 84 ' 85 hydrogen, water, 85 and even in a biosensor, 86 ' 87 based on the biocompatibility of this polymeric electrolyte.…”
