Abstract

Nafion 117™-SnO₂composite membranes were prepared by in-situ particle formation using an ion-exchange method. SnO₂was incorporated into Nafion 117ä membranes by ion-exchange in solutions of SnCl₂ ∙2 H₂O in methanol, followed by oxidation to SnO₂ in air. By adjustment of the concentration of SnCl₂ ∙ 2 H₂O used in the ion-exchange step, compositions ranging from 2 to 8 wt% SnO₂ with SnO₂ homogeneously distributed as nanoparticles were obtained.

The prepared nanocomposite membranes were characterized by powder XRD, ¹¹⁹Sn MAS NMR spectroscopy, electrochemical impedance spectroscopy, water uptake, tensile stress-strain measurements and thermogravimetric analysis. A SnO₂ content around 4 wt% gave a significant increase in membrane stiffness without losses in conductivity.
