Solid Polymer Electrolytes Based on Methylcellulose: FT-IR and Ionic Conductivity Studies

摘要

Polymer electrolytes of methylcellulose (MC) as the polymer host and ammonium fluoride (NH₄F) as a dopant were prepared by the solution casting technique. Fourier Transform-infrared (FT-IR) spectroscopy and X-ray diffraction (XRD) were used to study the complexation between the salt and polymer. The highest ionic conductivity value was found to be 6.40 × 10−7 Scm−1 at room temperature (303 K) for sample AF-18. The conductivity-temperature plots were found to follow Arrhenius behavior with the highest conductivity that gives low activation energy.View full textDownload full textKeywordsArrhenius behavior, FT-IR, Ionic conductivity, Methylcellulose, Polymer electrolyte, XRDRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/1023666X.2010.493291
