Nafion is a sulfonated tetrafluorethylene copolymer that has been widely used as a proton conductor for proton exchange membrane, in fuel cells, and biosensor applications. We attempt to incorporate a nanoparticle into nafion to improve its proton conductivity. Nafion-nanoparticale composite membranes were extensively characterized using scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier-transform infrared spectroscopy (FT-IR) X-ray photoelectron spectroscopy (XPS), and impedance method. For monitoring mammalian cellular behavior, cell proliferation and adhesion were assessed by mitochondrial function(MTT assay, WST assay) and cell morphology. |
