Abstract
Inventia se refera la un procedeu de obtinere a unor membrane schimbatoare de cationi prin functionalizarea directa a unor folii de poliolefine, introducînd grupari anionice cu ajutorul unor agenti de sulfonare. Functionalizarea este urmata de îndepartarea acidului nereactionat prin spalare cu solventi clorurati, metanol si apa. Se obtin astfel, fara prelucrari ulterioare, membrane cu conductivitate si permeabilitate foarte buna, utilizabile ca separatori interpolari în reactoare electrochimice, în surse electrochimice, în surse electrochimice neconventionale de energie si la elaborarea de dispozitive pe baza de electrolit polimer solid.
