Abstract

Phosphorylated TiO₂ nanotubes, synthesized through the Kabachnik-Fields reaction, are embedded in Nafon polymer to prepare composite membranes via a solution-cast method. The microphase separation of the composite membranes is tuned by the incorporated nanotubes, resulting in larger and more-connected hydrophilic ionic channels in the membranes. Compared with a pure Nafion membrane, the composite membranes show higher ion exchange capacity and water uptake. At 100℃, the proton conductivity of the composite membrane with 1% phosphorylated TiO₂ nanotubes reaches 0.154 S·cm^-1 from 0.139 S·cm^-1 of a pure Nafion membrane. The performance of the composite membrane at high temperatures is enhanced by the phosphorylated TiO₂ nanotubes.
