The thermal behavior and non-isothermal degradation of magnetite (Fe3O4)/Epoxidized Natural Rubber (ENR-50) composites, lithium triflate (LiCF3SO3)-ENR-50 polymer electrolytes (PEs) and LiCF3SO3-Fe3O4/ENR-50 composite polymer electrolytes (CPEs) were investigated using differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis. The glass transition temperature (Tg) of the studied materials generally follow the order of increasing values; ENR~Composite
