Summary: Room temperature ionic liquid: 2,3-dimethyl-1-octylimidazolium hexafluorophosphate (DMOImPF 6 ) has been incorporated in polyvinylidenefluoride -cohexafluoropropylene (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 Â 10 À3 S/cm at 120 8C 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.
Ionic recombination is the primary channel for the formation of the XeCl exciplex. However, there are two additional channels that are also important. These channels take advantage of the pseudo-crossings of two Rydberg-state potential-energy curves with the ionic curve. The three-body rate coefficients for the formation and associated reverse processes are calculated using semi-classical formulae derived on the basis of a double-crossing electron-jump model. Specific results for the.three-body ionic-recombination rates of Xe + and CI are compared with those obtained using classical theories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
