A gel polymer electrolyte (GPE) was successfully prepared by means of an in situ cross-linking reaction of poly(2-vinylpyridine-co-styrene) and oligo(ethylene oxide) with epoxide functional groups at 65°C without using a polymerization initiator. A stable gel polymer electrolyte could be obtained by adding only 1% of a polymer gelator. The ionic conductivity of the GPE containing 99wt% of liquid electrolyte...
Clay-nanocomposite thin films were deposited on the Nafion membranes by layer-by-layer assembly, in order to enhance resistance of the membrane against methanol transport. The bilayers of exfoliated clay nanosheets and ionic polyacetylenes (PEPy-C18) were found to build up successfully on the substrate as the linear increase of UV–vis absorption intensity of the multilayer films. The TEM image of...
