In this work, the organic-inorganic hybrid membranes were prepared. The synthesis and properties of the hybrid membranes were investigated. The sulfonated poly(arylene ether ketone sulfone) containing amino groups (Am-SPAEKS) was synthesized by nucleophilic polycondensation. The sol-gel method was used to prepared functional titania inorganic particles (L-TiO2). The 1H NMR and FT-IR were performed to verified the structure of Am-SPAEKS and L-TiO2. The organic-inorganic hybrid membranes showed both good thermal stabilities and mechanical properties than that of Am-SPAEKS. The L-Am-15% membrane exhibited the highest Young’s modulus (2262.71 MPa) and Yield stress (62.09 MPa). The distribution of L-TiO2 particles was revealed by SEM. Compared to Am-SPAEKS, the hybrid membranes showed higher proton conductivities. The L-Am-15% exhibited the highest proton conductivity of 0.0879 S cm-1 at 90 oC. The results indicate that the organic-inorganic hybrid membranes have potential for application in proton exchange membrane fuel cells.
