Synthesize and characterization of Ag-CuO/rGO nanoparticles as a filler of the PVDF polymer to improve its polar β phase and electrical conductivity for polymer batteries applications

Abstract

This article presents the synthesis and characterization of Ag-CuO/rGO nanoparticles, which serve as a filler for the PVDF polymer to enhance its polar β phase and electrical conductivity for possible use in polymer batteries. The Ag-CuO/rGO nanoparticles were prepared through a straightforward hydrothermal method and incorporated into a PVDF matrix using a solution casting technique. Various techniques were employed to examine the structure, crystallinity, dielectric, and electrical properties of the PVDF/Ag-CuO/rGO nanocomposites. The results revealed that the Ag-CuO/rGO nanoparticles incorporated within the PVDF matrix, promoting the formation of the polar β phase of PVDF. The PVDF/Ag-CuO/rGO nanocomposites displayed a higher dielectric constant and lower dielectric loss compared to pure PVDF. As the Ag-CuO/rGO content increased, so did the electrical conductivity of the nanocomposites, reaching a value of 1.23 × 10− 3 S/cm at 2.5 Wt% Ag-CuO/rGO loading. The enhanced electrical conductivity was attributed to the conductive networks formed by both the Ag-CuO/rGO nanoparticles and the polar β phase of PVDF. These findings indicate that PVDF/Ag-CuO/rGO nanocomposites hold promise for different applications such as polymer batteries.
