Polymer Electrolyte Membranes Based on Room Temperature Ionic Liquid: 2,3-Dimethyl-1-octyl imidazolium hexafluorophosphate (DMOImPF6)

摘要

Room temperature ionic liquid: 2,3-dimethyl-1-octylimidazolium hexafluorophosphate (DMOImPF6) has been incorporated in polyvinylidenefluoride -co- hexafluoropropylene (PVdF-HFP) to develop non-aqueous polymer electrolyte membranes. The conductivity of polymer electrolyte membranes depends upon the composition of ionic liquid and maximum conductivity of 1.35 ?nbsp;10-3 S/cm at 120 has been observed. The addition of plasticizers has been found to enhance the conductivity of polymer electrolytes by one order of magnitude which depends upon the dielectric constant of plasticizer.
