Synthesis and characterization of Nafion((R))-115 nanowire arrays.

Aligned Nafion((R))-115 nanowire arrays have been synthesized by an extrusion method with anodic aluminium oxide (AAO) membranes templates in this work. A surface modification was carried out to improve the hydrophobicity of the AAO pore surface. The as-synthesized nanowires are about 85 nm in diameter and several to over ten micrometres in length. Near-IR Raman and IR spectrum studies show that the polymer nanowires are composed of pure Nafion((R))-115 only.
