Investigations on the morphology and conductivity of peo / enr-25 / liclo4 blend in relation to atr-ftir study on the blends / Nurhayati Kamyon

Blends of PEO/ENR/LiC104 were prepared by solution casting technique. Conductivity (er) of poly(ethylene oxide) (PEO), a semicrystalline polymer and an amorphous epoxidized natural rubber with 25 mol% epoxidation level (ENR-25) doped with Y = 0.00 to Y = 0.20 (lithium perchlorate) LiC104 were studie...
