Proton conducting polymer electrolytes

This observation indicates: i) The formation of the lamellar grains; ii) The rapid changes in characteristic sizes of the lamellar grains compared with the lamellar stacks; and iii) The newly generated phases consisting of only the graft materials. These findings explain why the lamellar grains and the graft chains play an important role in the higher proton conductivity and compatible tensile strengths of the membranes, compared with Nafion, at the immersed and severe operating conditions.

Proton-conducting polymer electrolyte films were prepared by dissolving NH4I salt in polyethylene oxide/methylcellulose (PEO/MC) blend polymers using the solution cast technique. The semi-crystalline nature of the sample was identified from the X-ray diffraction (XRD) pattern. The surface morphology on the electrical conductivity was analyzed by scanning electron microscopy (SEM).

Proton conducting polymer electrolytes based on PVA, amino acid proline and NH4SCN were prepared by the solution casting technique. An increase in the amorphous nature of the polymer electrolytes was confirmed by X-ray diffraction analysis. DSC measurements showed a decrease in Tg with increasing salt concentration

Introduction: Other than in solutions or in ionic liquids, ionic conduction can take place in the solid state also. The solids that exhibit ionic conduction are called ‘solid-state ionic conductors’. Based on the charge of ionic species responsible for the conduction, they are divided into cationic and anionic conductors; then, based on specific species involved in the conduction, they are further subdivided into sodium ion conductors, proton conductors, fluorine ion conductors, and so on.
