Relaxation dynamics and conductivity in poly(vinylidene fluoride)/graphene oxide composites

Year: 2024

Type: article

Abstract: The α c relaxation, which originates from the crystalline phase of Poly(vinylidene fluoride), is studied in the composite system of Poly(vinylidene fluoride) and Graphene oxide . PVDF/GO composites were prepared using solvent casting . The crystalline phases in PVDF/GO composites were identified using XRD and quantified using FTIR . The thermal properties were analyzed using DSC , and the crystallization degrees were calculated. The electric modulus formalism is employed to understand the relaxation mechanism with temperature. AC conductivity studies reveal the activation energy for conduction in these composites.
