Abstract
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.
