The Nafion is a perfluorinated ionomer that is studied extensively in Proton Exchange Membrane Fuell Cell(PEMFCs). The Nafion contains a hydrophobic fluorocarbon backbone and perfluoroether side chains terminating in a high acidic, hydrophilic ionic pendant group, sulfonic acid. And the PVDF(Polyvinylidene fluoride) is also a perfluoronated polymer with high crystallinity. The crystallinity of PVDF induce the array of nafion which has the sulfonated group which is hydrophilic. From Small angle X-ray scattering (SAXS), Atomic force microscope (AFM), it is confirmed that the crystallinity of Nafion/PVDF films. Finally, The increase of Proton conductivity is confirmed. |
