Study of Chemical Modified Amphoteric Ion Exchange Membrane from Taurine

Fluorinated poly(aryl ether oxadiazole), synthesized by the copolymerization of 2,5-bis(2,3,4,5,6-pentafluorophenyl)-1,3,4-oxadiazole and diallylbisphenol A, was used as the main polymer chain (MP). 2-aminoethanesulfonic acid (taurine) was attached to brominated-MPs (Br-MPs) at mild conditions, serv...

Summary:Fluorinated poly(aryl ether oxadiazole), synthesized by the copolymerization of 2,5-bis(2,3,4,5,6-pentafluorophenyl)-1,3,4-oxadiazole and diallylbisphenol A, was used as the main polymer chain (MP). 2-aminoethanesulfonic acid (taurine) was attached to brominated-MPs (Br-MPs) at mild conditions, serving as both cation and anion exchange groups. AIEM-0.6, AIEM-1.4 and AIEM-2.0 were obtained via solution-casting method. Quantum calculation and experiments verified the selective permeability of the membranes: high proton conductivities and low vanadium permeation parameters. Also the AIEMs demonstrate good acid resistance and thermal stability, showing potential in vanadium redox flow battery (VFB) fields.
