Abstract：

A series of multi-block sulfonated polyethersulfone with various sulfonation degree of 44.6%, 49.7% and 55.4% were synthesized, which were thus prepared as proton exchange membrane in direct methanol fuel cell. A type of interpenetrating networks was observed in these four-block sulfonated polyethersulfone membranes. Therefore, compared with the two-block sulfonated polyethersulfone, these prepared four-block sulfonated polyethersulfone membranes exhibited improved proton conduction performance. As the temperature and sulfonation degree increased, the water absorption, methanol transmissivity, ion exchange capacity and proton conductivity of the prepared proton exchange membrane were also increased. When the temperature was 90 °C, sulfonation degree was 55.4%, the proton conductivity of the corresponding membrane was as high as 9.38×10-3 S/cm, and the methanol transmittance was relatively low as 3.80×10-8 L/m·s.
