摘要: Ion-exchange membranes modified with sulfonic (-SO3H) and phosphonic acid (-PO3H) groups were prepared by radiation-induced grafting of glycidyl methacrylate (GMA) onto polyethylene (PE) films sub-sequent sulfonation phosphonation poly(GMA) graft chains. The surface area, thickness volume grafted PE film increased increasing yield. specific electrical resistance membrane the -PO3H -SO3H decreased ion-exchange capacity. group had a lower than that group.
