Phase behaviour and morphology in blends of polyether and polyacrylate with the addition of lithium salt / Assoc. Prof. Dr. Sim Lai Har … [et al.]

Solution casting technique is employed to prepare the poly(ethylene oxide) (PEO)/ polyacrylate (PAc) blends. Thermal behaviour and ionic conductivity of the PEO/PAc and PEO/PAc blends added with LiCI04were investigated using differential scanning calorimetry (DSC) and impedance spectroscopy (IS), re...
