▎ 摘　　要

Sulfonated polyphenylene sulphide sulfone (sPPSS) loaded with titania-graphene (TiO2-GNS) was synthesized by the polycondensation method and studied their suitability towards proton exchange membrane fuel cell applications. The structural, morphological, and physic-chemical properties of sPPSS nanocomposites containing varying amounts of (1%, 2%, 3%, and 5%) TiO2-GNS was investigated by Fourier transform infrared, H-1-NMR, P-XRD, FE-SEM, HR-TEM, Raman spectrum, swelling ratio (SR), water uptake, thermal analysis, oxidative stability (OS) and proton conductivity. Further, the obtained TiO2-GNS dispersed polymer membrane exhibits greatly reduced water absorption 4.44% and a less volume SR (15.6%). The 5 wt% TiO2-GNS dispersed sPPSS nanocomposites exhibited a PC value around 2.03 x 10(-2) S/cm at 110?. The sPPSS nanocomposites membrane confirmed admirable OS with a maximum degradation of 39.15% during immersed in the Fenton reagent for 6 h at 80?.
