Morphology, chemical interaction, and conductivity of a PEO-ENR50 based on solid polymer electrolyte
A solid polymer electrolytes (SPE) comprising blend of poly(ethylene oxide; PEO) and epoxidized natural rubber as a polymer host and LiCF3SO3 as a dopant were prepared by solution-casting technique. The SPE films were characterized by field emission scanning electron microscopy to determine the surf...
