Perfluorinated ionic membrane is the core material of vanadium batteries, flow batteries, fuel cells, ionic membrane electrolyzer, electrochemical sensor, For nearly half a century it has been produced exclusively by dupont using the melt extrusion process.However, such a method has defects such as complicated technology, expensive production equipment, inability to realize the recycling and utilization of perfluorinated ion membrane, high cost, low crystallinity, small tensile strength, large linear expansion rate, anisotropy and short service life.
CEC uses solution casting method to produce perfluorinated membrane, which has a series of outstanding advantages, such as simple technology, cheap production equipment, regenerable and recyclable perfluorinated membrane, low cost, high acid capacity, high conductivity, high crystallinity, high tensile strength, small linear expansion rate, isotropy and long service life
