Solid polymer electrolytes (SPEs) of Poly(sodium 4-styrenesulfonate) (PSS) as a
polymer host and lithium perchlorate (LC) as an ionic dopant were prepared using a singlesolvent
via solution casting technique. According to XRD analyses, the solid polymer electrolyte
films were in amorphous phase and the coexistence of peaks of the materials (PSS and LC)
confirmed that the complex films were successfully obtained. The SEM observations revealed
that the films appeared to be rough, flat, and irregular shape of surfaces. The highest ionic
conductivity (σ) of 7.21 × 10-6 S cm-1 was achieved at room temperature (303K) for the sample
containing 15 wt.% LC.
Keywords: solid polymer electrolyte; poly(sodium 4-styrenesulfonate); lithium perchlorate; ionic conductivity; impedance spectroscopy. |
