ABSTRACTSulfonated poly(phthalazinone ether sulfone ketone) (SPPESK)‐based composite membranes doped with hydrated tungsten oxide were prepared and studied for proton‐exchange membrane applications. Hydrated tungsten oxide (WO3· 2H2O) was synthesized from acidic hydrolysis of sodium tungstate. The SPPESK/WO3 composite membranes were prepared by mixing proper amounts of SPPESK and hydrated WO3 in dimethylacetamide as casting solvent. The composite membranes were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), and atomic force microscope (AFM). Infrared results indicated that the adding of WO3· 2H2O did not destroy the structure of polymer. In particular, SEM as well as AFM measurements showed a dense structure of the membranes, and the homogenous dispersion of WO3· 2H2O TGA results revealed thermal stability of the composite membranes at below 200 °C. The conductivity of the SPPESK/WO3 (30 wt%) composite membrane was about 0.033 S/cm at 140 °C under 100% relative humidity. The methanol permeabilities of the SPPESK/WO3 composite membranes were in the range of 1.715 × 10−7 to 0.496 × 10−7 cm2/s, much lower than that of Nafion® 117 (2.4 × 10−6 cm2/s). The presence of the oxide not only enhanced the proton conductivity of the SPPESK membranes but also improved their heat resistance and therefore decreased the methanol permeabilities.
