The hydrolysis and condensation of 3-aminopropyltrimethoxysilane or zirconium tetrapropylate in these polymeric matrices were used to produce poly(3-aminopropyl silsesquioxane) or ZrO2,as nano-fillers. Contrary to previous results reported for membranes containing phosphotungstic acid,the PMoA coalesced into mass-fractal structure,with fractal-dimension 1.85. The largest fractal aggregate was about 524 A˚ . Moreover,WAXS curves evidenced the crystallization of this heteropolyacid during the casting process. No changes concerning the distribution of PMoA were observed in the membranes containing SPEEK,PMoA and the poly(3-aminopropyl silsesquioxane).,On the other hand,no crystallization of the heteropolyacid was observed in the membranes containing ZrO2,although,denser surface fractal-like structures constituted by the heteropolyacid were observed.}, note = {Online available at: \url{https://doi.org/10.1016/j.jnoncrysol.2005.06.007} (DOI).
