The coagulation impact of 50% epoxidised natural rubber chain in ethylene carbonate-plasticized solid electrolytes

In this research, thin, soft and flexible free standing films can be obtained from poly (methyl methacrylate) (PMMA)/50% epoxidised natural rubber (ENR 50)/lithium triflate (LiCF(3)SO(3)) blends. However, phase separation is observed on the surface of the films which indicates that the blending is n...
