The use of solid polymer electrolytes (SPEs) is becoming main attention due to the
problems arising from liquid and gel polymer electrolytes. The purpose of this study is
to investigate the performance of the conductivity for alkoxy substituted chalcone
derivatives compounds 2a and 2b. Both compounds has been synthesized and
characterized followed by analyzed with Electrical Impedance Spectroscopy (EIS).
SPEs thin films from carboxymethyl cellulose, CMC as the polymer host doped with
dopant salt of 16 wt.% ammonium chloride, AC and added with varied amounts (0 -
8 wt. %) of 2a and 2b respectively as plasticizer via solution casting method has been
prepared. It showed that from the spectroscopic results, the highest ionic conductivity
for 2a was obtained at 6 wt.% which was 2.3 × 10 -2 S/cm meanwhile 2 wt.% for 2b
that was 1.7× 10 -2 S/cm. Therefore, 2b has a better conductivity than 2a as SPEs.
