摘要：

A series of composite membranes based on sulfonated polyether ether ketone with embedded powdered heteropolycompounds was prepared and their electrochemical and thermal properties were studied. An increase in degree of sulfonation as well as introduction of these fillers resulted in increased Tg and enhanced membrane hydrophilicity, bringing about a substantial gain in proton conductivity. The conductivity of the composite membranes exceeded 10(-2) S/cm at room temperature and reached values of about 10(-1) S/cm above 100 degrees C. (C) 2000 Elsevier Science B.V. All rights reserved.
