摘要：

This paper is focused on line of domains diversification of proton exchange membranes, by the synthesis of three new materials: poly(monobrom-2.6-dimethyil-1.4-phenyleoxid)-PPOBr, sulfonating polyetherethereketone (SPEEK) and sulfonating polysulfone (PSS). The structures and characteristics of polymers confer membranary materials special properties imposed for electromembranary applications: lower electrical resistance, high counter-ions permeability, high permselectivity, high mechanical resistance, dimensional stability, chemical stability in the whole range of pH, high thermal stability. The membranes obtained from PPOBr, SPEEK and PSS were characterized by specific methods, to give evidence of their performances, comparatively with commercial membranes (Nafion cationic, and ExcellionTM - anionic), which are very expensive.
