Composite Ion Exchange Membrane Description
Composite Ion Exchange Membrane (electrolysis and electroplating) uses high-strength polytetrafluoroethylene mesh as the support layer, and is matched with perfluorosulfonic acid resin with appropriate molecular weight and ion exchange capacity to form a composite membrane with uniform thickness.
Composite Ion Exchange Membranes (CIEMs) offer significant advantages over traditional membranes by combining the best properties of multiple materials. They play a crucial role in energy storage (flow batteries), power generation (fuel cells), and water purification. Their ability to improve selectivity, conductivity, and durability makes them essential for sustainable technologies, particularly in renewable energy systems and industrial water treatment.
