Composition and Structure Progress of the Catalytic Interface Layer for Bipolar Membrane. [PDF]

Nanomaterials (Basel), 2022
Bipolar membranes, a new type of composite ion exchange membrane, contain an anion exchange layer, a cation exchange layer and an interface layer. The interface layer or junction is the connection between the anion and cation exchange layers.
