In this study, a polymer-blend system consist of Carboxy Methylcellulose (CMC)-Chitosan (CS) as blend biopolymer host and doped with various composition of Dodecyltrimethyl Ammonium Bromide (DTAB) were successfully prepared via solution casting techniques. The new system has been analyzed through Electrical Impedance Spectroscopy (EIS) from temperature 303 K until 393 K to determine the conductivity of biopolymer electrolytes in the frequency range of 50 Hz to 1 MHz and the voltage between 5 to 50 mV. The optimum conductivity (1.86×10?6 S.cm?1) at ambient temperature obtained for composition of 5 wt.% DTAB. The temperature dependence of ionic conductivity was found to obeys the Arrhenius rule where R2?1 and thermally activated. The dielectric studies show a non-Debye behavior of SBEs based on the analyzed data using complex permittivity, e* and complex electrical modulus, M* of the sample at selected temperature.

Green materials of the future 2 – Hydroxyethyl cellulose (2-HEC) doped with dodecyltrimethyl ammonium bromide (DTAB) have been prepared via solution cast technique. The typical XRD pattern shows this complexation has taken place in the amorphous phase. The system with 9wt. % DTAB presented the highest conductivity at room temperature, 2.80 x 10-5 S cm-1 and ionic conductivity was observed to be influenced by the DTAB concentration. It was found that the conductivity measurement at elevated temperatures follow Arrhenius model and dielectric values were found to increase with increasing temperature, thus indicating the green solid biopolymer electrolytes (SBEs) system to be a non–Debye type. Jonscher’s universal power law was employed to obtain the exponent s values. The results imply that the conduction mechanism in the most conductive green SBEs system can be represented by small polaron hopping (SPH) model.
