“…In addition, a long tail at low frequencies depicts that there might be a large capacitance associated with the electrodes polarization effects which further confirms non-Debye behavior in the samples [52,53]. According to Bakar et al (2015) [54], modulus part increase as frequency increase due to bulk polarization which can be differentiate into two elements; (i) transferred by electron and (ii) avalanche transittime. In the present work, it is believed the bulk effects appeared in the complexes due to transferred by electron between host polymer and ionic dopant.…”

In this present work, the conduction properties of biopolymer electrolytes (BEs) based alginate incorporation with LiNO 3 was studied. FTIR analysis showed there is complexation occurred when incorporation with LiNO 3 via COO − group of alginate. The interaction between alginate and LiNO 3 shown an improvement in ionic conductivity of BEs where was increased from 3.24×10 -7 S cm −1 for un-doped sample and achieved optimum value at 1.14×10 -4 S cm −1 for sample containing with 15 wt. % LiNO 3 . The prepared samples shown that it has thermally assisted when the temperature is increased and shown Arrhenius behavior. Deconvolution approached revealed that the present ionic conduction of BEs influenced by ionic mobility and diffusion coefficient.

“…However, the values increased as frequency increased from 3 Hz to 5 Hz. Increasing modulus (Mr and Mi) values at higher frequencies might be assigned to the bulk effect [22], [23]. The appearance of this long tail at low frequencies is due to the large capacitance applied with the electrodes [22], [24].…”

“…Increasing modulus (Mr and Mi) values at higher frequencies might be assigned to the bulk effect [22], [23]. The appearance of this long tail at low frequencies is due to the large capacitance applied with the electrodes [22], [24]. The modulus values are at zero vicinity, indicating a small polarization, which is the main advantage of Mr and Mi modulus studies.…”

The blended carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA) doped with various compositions of ammonium bromide (NH4Br)-based solid biopolymer electrolytes (SBEs) were prepared by using the casting method. In this present work, CMC/PVA-NH4Br SBE thin film was used to investigate the electrical conductivity via electrical impedance spectroscopy. The maximum conductivity obtained was 3.21 X 10 −4 S cm −1 for sample AB20 at ambient temperature (303 K), and this result might be due to the increased number of charge carrier. A dielectric study was conducted to understand the conductivity behavior. The electrical properties have been measured as a function of frequency of ɛr, ɛi, Mr, and Mi, indicating a non-Debye type behavior.

“…Biopolymers are extracted from a wide range of resources such as cellulose derivatives, chitosan, carrageenan, pectin, starch and lignin [4][5][6][7][8][9][10]. These polymers possess a lone pair electron of the heteroatom such as nitrogen or oxygen and hence ionic dopant can be solvated [11].…”

Biopolymer electrolytes based on dextran from Leuconostoc mesenteroides doped with ammonium nitrate (NH 4 NO 3) are synthesized via a solution cast method. Fourier transform infrared analysis is used to determine the complexation between cation from the salt with functional groups of dextran. The ionic conductivity of undoped dextran film at room temperature is identified as (8.24 ± 0.31) × 10 −11 S cm −1. A conductivity of (3.00 ± 1.60) × 10 −5 S cm −1 is achieved with the inclusion of 20 wt% NH 4 NO 3 to the pure dextran film. The conductivity at a high temperature of the electrolyte obeys Arrhenius theory. Field emission scanning electron microscopy results show that the highest conducting sample has a porous surface. Results from the dielectric study show a non-Debye characteristic.
