Abstract
The distribution of ZrO2 and phosphotungstic acid (PTA) in a matrix of sulfonated polyether ketone was investigated by anomalous small-angle X-ray scattering (ASAXS). Scattering curves were obtained using X-ray energies near the Zr and W absorption edges, allowing the independent analysis of the distribution of ZrO2 and PTA in the sample. The interaction between both inorganic components improved their dispersion considerably when compared with films containing just one of the additives. The synergism was correlated to previous investigations concerning proton conductivity and permeability of the membranes developed for direct methanol fuel cell.
