Various composition of solid polymer electrolyte based on corn starch complexed with<br />

sodium hydroxide and glycerol as plasticizer were prepared using solvent cast<br />

technique. Optimum ionic conductivity, 3.93 X 10 -3 S/cm was recorded with<br />

composition of 25wt% NaOH. Complexation of starch and NaOH in polymer matrix<br />

were proven with the increase in intensity of peak from the result of Fourier Transform<br />

Infrared Spectroscopy (FTIR). Crystallinity of polymer thin film was determined by<br />

XRD spectroscopy, proven that complexation occur and crystallinity peak emerge for<br />

higher concentration of NaOH. Surface morphology was carried out with scanning<br />

electron microscope.<br />
