Nafion thin film
WitrynaThin films of amphiphilic ionic polyacetylenes based on poly (N-octadecyl-2-ethynylpyridinium bromide) were formed using the Langmuir-Blodgett and layer-by-layer deposition techniques. ... Enhanced gas permeability and permselectivity of membranes from Nafion were achieved by deposition of ultrathin films of the above polyacetylene … WitrynaCommercial Nafion membranes have been widely used for vanadium redox flow batteries (VRFB) but with relatively low ion selectivity. A chemical method is commonly employed to modify the organic membranes, whereas physical approaches are rarely reported in view of less compatibility with the organic species. In this study, an …
