摘要：
PMMA-PVC polymer blend systems with LiTFSI as dopant salt were prepared by solution casting technique. Studies were then performed to explore the ionic conductivity, crystallographic structure, morphology, and thermal properties of these polymer electrolytes. XRD and SEM reveal amorphous behavior and morphologies of polymer electrolytes, respectively. Coherent length was calculated to determine the amorphousity of polymer complexes. Ionic conductivity was calculated using ac-impedance spectroscopy. DSC measurements revealed a decrease in T (g), whereas T (m) and T (d) were enhanced. The thermal properties of polymer electrolytes were found to enhance upon addition of 30 wt% LiTFSI. Increase in thermal stability of polymer electrolytes were further confirmed through TGA studies.
