Conductivity Studies Of Starch Based Polymer Blend Electrolyte

In this present study, starch has been blended with poly (ethylene oxide) (PEO) and from XRD study the starch/PEO with ratio 7:3 exhibits the least amount of crystallinity and was chosen in the preparation of polymer electrolyte. Films of starch/PEO blends were then prepared via solution casting tec...
