A hybrid bipolar membrane

Journal of Membrane Science, 2010
Abstract A hybrid bipolar membrane was developed for high-temperature applications. In particular, the cation-exchange layer was prepared by hybridizing sulfonated poly (2,6-dimethyl-1,4-phenylene oxide) (SPPO) with (3-aminopropyl) triethoxysilane (A1100) while the anion-exchange layer was prepared from a hybrid anion-exchange material—poly(VBC-co-γ ...

Development of bipolar membranes

Desalination, 1988
Abstract The large-scale industrial use of bipolar membrane for the production of acids and bases from the corresponding salts is limited by the properties of the commercially available bipolar membranes. Today's membranes are unsatisfactory in terms of their selectivity and chemical stability at high pH values.

Studies on bipolar membranes

Reactive and Functional Polymers, 1996
Abstract Bipolar membranes are composed of two distinct layers which are selective to ions of opposite charges. Because of this unique characteristics, bipolar membranes are able to electrically separate water into hydrogen and hydroxyl ions. These membranes in conjunction with conventional cation- and anion-exchange membranes in a cell stack, have ...

Electrohydrodynamics of Bipolar Membranes

Doklady Physics, 2018
On the basis of the Nernst−Planck−Poisson−Stokes system, the behavior of the electrolyte solution is numerically studied for the first time in bipolar electrical membranes under the action of an external electric field while taking into account water dissociation.

Bipolar Faradaic Interfaces in Bipolar Membranes

ECS Meeting Abstracts
In this work, we demonstrated that a pinhole-free, solid-state and electron-conductive membrane can function as an ion exchange membrane or a solid electrolyte through bipolarized Faradaic interfacial reactions. The bipolar Faradaic interface membrane (BFIM) is an insulator to ionic conduction in the bulk phase.

Bipolar Patterning of Polymer Membranes by Pyroelectrification

Advanced Materials, 2015
Polymer freestanding membranes with permanent bipolar patterns are fabricated by "pyroelectrification". The thermal stimulation of periodically poled lithium niobate (PPLN) crystals simultaneously generates the pyroelectric effect, the glass transition of the polymer, and therefore the periodic electric poling of the polymer.

Model for ion transport in bipolar membranes

Physical Review A, 1990
A simple theory for multi-ionic transport, nonequilibrium water dissociation, and space-charge effects in bipolar membranes is developed on the basis of some of the concepts used in the solid-state n-p junction. Ion transport is described in terms of the Nernst-Planck flux equation and nonequilibrium water dissociation is accounted for by the Onsager ...

Bipolar Membrane Electroacidification of Demineralized Skim Milk

Journal of Agricultural and Food Chemistry, 2001
The aim of this study was to evaluate the effect of decreasing the mineral content of skim milk by electrodialysis (ED) prior to electroacidification with bipolar membrane (BMEA) on the performance of the process, the chemical composition, and the physicochemical and functional properties of the isolates produced.

Electrodialysis with Bipolar Membranes for Sustainable Development

Environmental Science & Technology, 2006
Electrodialysis with bipolar membranes (EDBM) is a kind of technology that integrates solvent and salt dissociation. It can realize salt conversion without second salt pollution or provide H+ and OH-/alkoxide ions in situ without salt introduction. Thus, it inherently possesses economical and environmental benefits.
