dc.description.abstractThe study of biopolymer electrolyte has attracted many researchers to involve into the conductivity exploration cellulose as polymer electrolyte. The sago doped ammonium bromide thin film has been prepared in order to investigate the potential of sago as solid polymer electrolyte of the conductivity for these films. These solid polymer electrolytes were prepared by solution cast technique and analyzed by Electrochemical Impedance Spectroscopy (EIS), Fourier Transform Infrared Spectroscopy (FTIR) and Transference Number Measurement (TNM). In the EIS analysis, the highest ionic conductivity of this solid polymer electrolyte at room temperature was observed to be 6.90x10- 9 1 for sample with 15wt. % concentration of Ammonium Bromide (AB). The tem f erature dependence conductivity shows that it follows the Arrhenius rule where R -1. The FTIR spectra shows that the intensity of peak at 1020 cm· Scm· 1 change with increase wt. % of ammonium salt. This peak is due to C-0 stretching of C-0-C group in the anhydroglucose ring which is from polysaccharide structure in the sago. The peak at 2940 cm· 1 was increase in intensity due to increase of AB concentration indicates that some interactions occurred between sago and AB. The Transference Number Measurement (TNM) studies were conducted to determine and correlate the ionic diffusion phenomena with the conductivity behavior of Sago-AB. The conductivity values were found to be directly proportional and controlled by the ionic mobility and ionic diffusion coefficient. It also shows that these polymers are proton conductors.en_US
