“…Here, we have chosen a co-polymer of vinylidene fluoride and hexafluoropropylene (PVdF:HFP) which contains an amorphous phase capable of trapping large amount of electrolyte and a crystalline phase that acts as a mechanical support for the formation of a free standing film. PVdF-co-HFP exhibits high anodic stability and it shows compatible nature with other polymers [22,23].The choice of choosing LiClO 4 is due to its smaller ionic radius, smaller dissociation energy and the high solubility in most of the organic solvents. The interest on PVAc-based systems increases because PVAc offers good mechanical stability, low glass transition temperature, and easy film formation properties.…”

Polymer blend electrolytes comprising of poly (vinyl acetate), poly(vinylidene fluoride-co-hexafluoropropylene), LiClO 4 , and EC-based plasticizer combinations (EC ? PC, EC ? GBL, EC ? DMP, EC ? DBP, EC ? DEC) are prepared by solvent casting technique. Ionic conductivities of the electrolytes are determined by ac impedance studies in the temperature range 303-363 K. Among the various combinations of plasticizers, EC ? PC added complex exhibits maximum ionic conductivity of the order of 10 -4 S cm -1 and the temperature-dependent ionic conductivity plots seem to obey the VTF relation. The structural and complex formations of the prepared samples have been confirmed by X-ray diffraction analysis. DSC technique is used to study the thermal behaviour. The surface images of the sample having maximum ionic conductivity are analyzed with the help of SEM and AFM techniques.

“…Among the lithium salts commonly used LiN(C 2 F 5 SO 2 ) 2 may be promising for industrial applications due to its larger anion size and higher polarizability. Also, it is more effective in terms of the cation transport properties [20] . All the electrolytes were prepared by dissolving, appropriate amounts of polymer, plasticizer and lithium salt in anhydrous tetrahydrofuran (THF) as indicated in Table I.…”

Preparation and characterization of PVC/PMMA blend polymer electrolytes complexed with LiN(CF3SO2)2

Thin films of polymer blend electrolytes comprising Poly(vinyl chloride) (PVC) and Poly(methyl methacrylate)(PMMA) and plasticized with a combination of ethylene carbonate (EC) and propylene carbonate (PC) for different lithium imide salt, LiN(C 2 F 5 SO 3 ) 2 , concentrations were prepared using the solution casting technique. The films were subjected to a. c. impedance measurements as a function of temperature ranging from -30 °C to 70 °C. The variation of ionic conductivity as a function of temperature and PVC content in the blend was analysed. The role of PMMA in the phenomena occurring at the interface between the plasticized polymer electrolyte and lithium electrode was also studied. The cast films were also subjected to TG/DTA and FT-IR studies which are discussed.

“…The crystalline junctions will enter a melt if the melting temperature is exceeded due to the absence of chemical cross-links. These distinct properties of 2 PVDF have resulted in many publications on PGEs containing PVDF, as both the host polymer [13,14,15,16,17,18] and as part of co-polymer systems (such as PVDF-HFP) [19,20,21,22].…”
