Nanoscale Membrane Based on Filled Nanoporous Anodic Alumina with Proton-conducting Polymer for Fuel Cell Applications: Primary Morphological Evaluation

In this study, at the first an alumina substrates with oriented nanochannels were prepared via controlled anodizing process. Then structurally modified chitosan macromolecules with binary cross-link agents at optimum composition (12 and 2 wt. % of sulfosuccinic acid and glutaraldehyde) was introduced in the nanopores of inorganic substrate. Scanning electron microscope approved the uniform presence of a chitosan based nanorods inside the nanochannels of alumina substrate.
