Preparation and characterization of monovalent cation selective sulfonated poly(ether ether ketone) and poly(ether sulfone) composite membranes

SPEEK–zirconium hydrogen phosphate composite membranes with low methanol permeability prepared by electro-migration and in situ precipitation

“…Membrane conductance measurements were carried out in a cell composed of two platinum electrodes, which were separated by the membrane with 1 cm 2 effective area [30]. There was provision to pass hot solution into each compartment and actual temperature at the vicinity of the membrane surfaces was measured with the help of two thermocouples.…”

High-impact polystyrene/polyaniline membranes for acid solution treatment by electrodialysis: Preparation, evaluation, and chemical calculation

“…Therefore it is important to develop or adapt membranes with characteristics that are necessary to different uses of electrodialysis. Recently, many studies have been focused on membrane production using sulfonated polymers [9] or conducting polymers, especially polyaniline, which may present high environmental stability, easy polymerization, and low cost [10,11]. These materials have some properties that are not found in conventional polymers, such as electrochemical properties, when they are in the doped state [12].…”

SPEES/PEI-based highly selective polymer electrolyte membranes for DMFC application

“…From the SEM images, it can be seen that the PEI is well mixed with SPEES matrix and exhibits flat and smoother surface without obvious agglomeration. Also, no phase separation was observed on the membrane surface [29].…”
