“…For instance, perfluorosulfonic acid polymers are prepared by copolymerization of a series of perfluorinated comonomers under high temperature (always over 200 1C) induced by peroxide initiators. 220,248 The commonly-used fluorinated monomers including ethanesulfonyl fluoride and tetrafluoroethylene are prepared with 2-chloro-1,1,1-trifluoroethane at high temperatures (800-1000 1C) and hexafluoropropylene. Different monomers in copolymerization will lead to large differences in polymer structure, molecular weight, and distribution.…”

“…For instance, commercial perfluorosulfonic acid polymers were prepared under the conditions of high temperature and high pressure. 220,248 The energy consumption caused by high-temperature reaction during preparation is likely to be compensated by the carbon emission reduction brought by its high stability in future application which is anticipated. There lies considerable risk in the synthesis process (P5, P6 & P7).…”

Ion exchange membranes are widely used in chemical power sources, including fuel cells, redox batteries, reverse electrodialysis devices and lithium-ion batteries. The general requirements for them are high ionic conductivity and selectivity of transport processes. Heterogeneous membranes are much cheaper but less selective due to the secondary porosity with large pore size. The composition of grafted membranes is almost identical to heterogeneous ones. But they are more selective due to the lack of secondary porosity. The conductivity of ion exchange membranes can be improved by their modification via nanoparticle incorporation. Hybrid membranes exhibit suppressed transport of co-ions and fuel gases. Highly selective composite membranes can be synthesized by incorporating nanoparticles with modified surface. Furthermore, the increase in the conductivity of hybrid membranes at low humidity is a significant advantage for fuel cell application. Proton-conducting membranes in the lithium form intercalated with aprotic solvents can be used in lithium-ion batteries and make them more safe. In this review, we summarize recent progress in the synthesis, and modification and transport properties of ion exchange membranes, their transport properties, methods of preparation and modification. Their application in fuel cells, reverse electrodialysis devices and lithium-ion batteries is also reviewed.
