| description | The present work deals with the investigation on ionic conductivity and transports properties of biopolymer electrolytes (BEs) based on kappa-carrageenan (KC) by incorporating NH4Br as polymer-salt system. The BEs was successfully prepared via solution-casting method and characterized by means of Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and electrochemical impedance spectroscopy (EIS). It was established that the ionic conductivity for BEs system increased and achieved an optimum value of 3.89 × 10−4 S/cm for a sample containing 20 wt.% NH4Br at ambient temperature (303 K). XRD analysis indicates that the highest ion conductivity complex exhibits optimum amorphous nature via the evaluation of the degree of crystallinity (Xc %). The conducting element in the BEs does favor the association of ion count from NH4Br where the ionic mobility and diffusion coefficient of the transport properties were found increase parallel with the conductivity until it reaches optimum composition of BEs. |
