Correlated barrier hopping and ionic conduction mechanism in glycolic acid-doped alginate-PVA biopolymer electrolytes

This study examines the electrical and dielectric properties of solid polymer electrolytes (SPEs) based on an alginate-PVA blend doped with glycolic acid (GA). The AC conductivity as a function of frequency was observed to conform to Jonscher’s power law. The dielectric permittivity, dielectric loss...

description This study examines the electrical and dielectric properties of solid polymer electrolytes (SPEs) based on an alginate-PVA blend doped with glycolic acid (GA). The AC conductivity as a function of frequency was observed to conform to Jonscher’s power law.

It was found that an increase in GA content directly enhances the number of charge carrier (ŋ), ionic mobility (μ), and diffusion coefficient (D) of the SPEs system. The frequency exponent (s) was calculated and the correlated barrier hopping (CBH) model was used to explain the behaviour of the s value with temperature.
