Box 999, Richland, WA 99352, USA e-mail: [email protected]; [email protected] Lack of comprehensive understanding about the interactions between Nafion membrane and battery electrolytes prevents the straightforward tailoring of optimal materials for redox flow battery applications. In this work, we analyzed the interaction between aqua-vanadyl cation and sulfonic sites within the pores of Nafion membranes using combined theoretical and experimental X-ray spectroscopic methods. Molecular level interactions, namely, solvent share and contact pair mechanisms are discussed based on vanadium and sulfur K-edge spectroscopic analysis.

Modified CNTs/Nafion composite: The role of sulfonate groups on the performance of prepared proton exchange methanol fuel cell’s membrane
A novel Nafion®-based nanocomposite membrane was synthesized to be applied as direct methanol fuel cells (DMFCs). Carbon nanotubes (CNTs) were coated with a layer of silica and then reacted by chlorosulfonic acid to produce sulfonate-functionalized silicon dioxide coated carbon nanotubes (CNT@SiO2-SO3H). The functionalized CNTs were then introduced to Nafion®, and subsequently, methanol permeab...

The purpose of this study was to investigate the influence of electron beam (EB) irradiation on the structure and physical properties of Nafion 117 membranes (in both acid and sodium forms) when they are irradiated in water and isopropanol as solvents. The mechanical properties of Nafion membranes in acid form irradiated in water were found to rapidly deteriorate as the irradiation dose was inc...

─The Nafion/zeolite composite membranes were synthesized for polymer electrolyte fuel cells (PEMFCs) by adding zeolite in the matrix of Nafion polymer. Two kinds of zeolites, Analcime and Faujasite, were used. The physicochemical properties of the composite membranes such as water uptake, ion-exchange capacity, hydrogen permeability, and proton conductivity were determined. The fabricated compo...

The interaction of vanadyl ion with gliadin has also been studied by spectrophotometric and pH-metric methods. The nature of spectra of small ligands and liquid-polymer solution provides sufficient information about ligand-polymer interaction. Here, addition of only 0.57 × 10-4 M protein solution caused on increase in absence at a particular wavelengths. The solulder as well as the maximum abso...
