-Abstract
A novel polymer electrolyte membranes are prepared bycomprising of poly (vinylidene chloride -co-acrylonitrile)
(PVdC-AN), poly (methylmethacrylate) (PMMA) with different ratio, with constant ratio of lithium per chlorate (LiClO4), and
Zirconia (ZrO2) by solution cast technique. The formation of blend polymer electrolyte complex has been confirmed by XRD
and FTIR spectroscopy analysis. The ac impedance studies are carried out to depict role of blendingof polymers on
conductivity. The high ionic conductivity of 0.6 x 10-4
at 303K has been observed for the blend ratio 25:75 of PVdCAN:PMMA. The temperature dependence of the blend polymer electrolyte is found to obey VTF relation. TG/DTA analysis
has been performed in order to investigate the thermal stability of the blend polymer electrolyte. The three dimensional
topographical image of the blend are investigated using AFM.
