Electromembrane Processes, a Toolbox for Advanced Separations

Fabrication and Characterization of Proton Conductive Membranes Based on Poly(methyl methacrylate-co-maleic anhydride)

In this study, proton conductive composite membranes were produced by using a poly(methylmethacrylate-co-maleic anhydride) (P(MMA-co-MAH)) copolymer and phosphotungstic Acid (PWA) as an additive of the proton conductive agent. P(MMA/MAH) 70/30, 50/50, and 30/70 were synthesized using a free radical polymerization reaction. PWA with a concentration of 2% was added to...

Electromembrane Processes in Environment Protection

The separation membrane techniques in which an external electric field is applied as a driving force (such as electrodialysis, electro-electrodialysis, and membrane electrolysis) are shortly described and their application in environment protection is presented. Attention was focused on recovery of valuable chemicals from effluents and waste gases. Examples of new production methods that elimin...

Preparation of anisotropically proton-conductive materials based on poly(vinylidene fluoride) ion track membranes

Proton exchange membranes (PEMs) for polymer electrolyte fuel cells (PEFCs) have recently been developed by our original techniques of the γ-ray or electron-beam crosslinking and graft polymerization. Our additional main focus is the use of cylindrical damage in polymers produced by bombardment of high-energy ions, that is called a latent track. We are taking the approach using this ion track t...
