Studies on interpolymer membranes. Part III. Cation-exchange membranes

Reactive Polymers, Ion Exchangers, Sorbents, 1983
Abstract Studies have been conducted without use of solvents in the preparation of interpolymer bases for cation-exchange membranes using blends of high and low density polyethylenes with styrene-divinylbenzene copolymers. The blending ratios of polymer and copolymer with different degrees of crosslinking and their effects on the properties of the ...

Modification of ion-exchange membrane surface by plasma process. Part 2. Monovalent cation permselective membrane from perfluorosulfonate cation exchange membrane

Journal of Membrane Science, 1990
Abstract The monovalent cation perm-selectivity of a perfluorosulfonate cation-exchange membrane, Nafion® 117, was enhanced by depositing an ultra-thin anionic exchange layer on its surface. The anion exchange layer was prepared by plasma polymerization of 4-vinylpyridine followed by quaternization with 1-bromopropane. The resulting layers were about

Mathematical Modeling of a Cation-Exchange Membrane Containing Two Cations

Journal of The Electrochemical Society, 2008
Transport phenomena in an ion-exchange membrane containing both H + and K + are described using the multicomponent diffusion (extended Stefan-Maxwell) equations. Expressions for macroscopic transport parameters, i.e., conductivity, proton transference number, water electro-osmotic coefficient, and transport parameters characterizing diffusion at zero

Gas permeability of wet cation exchange membranes

Gas Separation & Purification, 1990
Abstract The permeation of CO2 across a Nafion cation exchange membrane in different hydrated forms is studied. The water solvent linked to the ion exchanging sites of the charged membranes forms a liquid supported membrane in which the transport of the polar gas is enhanced.

Cost effective cation exchange membranes: A review

Chemical Engineering Research and Design, 2012
Abstract This paper will look at developments of new polymer electrolyte membranes to replace high cost ion exchange membranes such as Nafion®, Flemion® and Aciplex®. These perfluorinated polymer electrolytes are currently the most commercially utilized electrolyte membranes for polymer electrolyte fuel cells, with high chemical stability, proton ...
