The effect of lithium perchlorate on poly (sodium 4-styrenesulfonate): studies based on morphology, structural and electrical conductivity


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 single-solvent 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 (PSSand 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.
