Polyethersulfone-graft-polystyrene was successfully prepared via atom transfer radical polymerization(ATRP) catalyzed CuCl4/1,1,4,7,10,10-Hexamehtyltriethylenetetraamine(HMETA) in DMSO. 1H NMR and FT-IR spectroscopy show that the “grafting from” method using ATRP was successful and the maximum grafting degrees were 35% PES-g-PSSA. The IEC value was 0.63 , water uptake was 46.8 w% and proton conductivitie was 0.079S/cm at room temperature, for PES-g-PSSA. Membranes exhibited excellent thermal stability up to around 350 oC, verified by thermal gravimetric analysis (TGA). |
