High ion conducting and thixotropic nature of water-soluble xanthan gum-based electrolytes
NARINDER ARORA VINEY SHARMA RAJIV KUMAR SIMRANJIT SINGH RAJESH KUMAR SUNAINA VERMA SHUCHI SHARMA
This research reports the preparation and characterization of xanthan gum (XG)-based gel electrolytes (GEs) comprising sodium hydroxide salt (NaOH) in deionized water (DW). The three-dimensional gel network has been formed without using any synthetic polymer or cross-linking agents. Ionic conductivity of GEs was evaluated with different parameters, such as salt concentration, gum concentration, temperature and with the passage of time. The maximum ionicconductivity of 74.8 mS cm$^{–1}$ was observed at room temperature even after 55 days for XG-based GE containing 0.625 M NaOH. A small change in pH values for XG-based GEs have been observed with temperature in the range of 10–70°C and at different time span. Thixotropic behaviour of GEs under the application of stress has also been analysed by rheological studies. There was no discernible change in ionic conductivity with temperature and with the passage of time, which make it desirable for their use in different device applications.
