Abstract: Two organized sulfonated polyimides (ASPIs) with bent polymer backbones were synthesized to study a relation between structure and proton conductivity. Proton conductivity exhibited different values between the thin film and bulk pelletized forms. Results from small-angle X-ray scattering (SAXS) and attenuated total reflection measurements suggest that the orientation of backbones is different between the thin film and bulk forms. SAXS results suggest excess amount of water uptake in the bulk samples compared to the thin film form. These structure and water uptake property could contribute the difference of the proton conductivity between the thin film and bulk pelletized forms.
