ASAXS revealed that ZrO2 was distributed in the SPEEK matrix in the form of nanoparticles smaller than 13 Angstrom. A decrease in the conductivity suggested that the sulfonic groups were bound to the zirconium oxo species at the particle surface. Furthermore, two kinds of membranes containing zirconium phosphate were investigated. In one case, the phosphate was directly dispersed in the polymer solution for the casting of the membrane. In the other case, the phosphate was previously treated with n-propyl ammonium and polybenzimidazole. From ASAXS data, the fractal dimension could be estimated. Mass-fractal behavior was confirmed for the SPEEK membrane containing previously exfoliated zirconium phosphate, with aggregates of 6.3-165 Angstrom. Surface-fractal behavior was detected for membranes with untreated phosphates, with aggregates of 6.4-185 Angstrom. The untreated phosphates caused an increase in the permeability, without changing the proton conductivity much.
