Improving the ionic conductivity in nanostructured membranes based on poly(vinyl alcohol) (PVA), chitosan (CS), phosphoric acid (H3PO4), and niobium oxide (Nb2O5)
Nanostructured membranes based on poly(vinyl alcohol) (PVA) and chitosan (CS) weight ratio of PVA:CS (80:20), mixed with 40% phosphoric acid (H 3 PO 4 ) and finally doped with nanoporous niobium oxide (Nb 2 O 5 ) at different concentrations, were prepared by solution casting method. The ionic transp...
