Abstract

AbstractThis study focused on examining and comparing the effects of Bi2O3, WO3, and ferroelectric Bi2WO6 ceramic particles on the frequency‐dependent electrical properties of the epoxy matrix, which is known for its good mechanical strength, easy processability, high oxidation resistance, low dielectric loss, sealing and adhesive properties. While the reinforcing particles as well as the composites were examined by FTIR analysis, electrical measurements were carried out at room temperature with an impedance analyzer in the range of 20 Hz‐1 MHz. The energy storage performances of the three composite families were compared by limiting the analysis to the real and imaginary components of the complex dielectric constant (ε′ and ε′′ ) , ac conductivity, and phase angle. When the ε' and ε′′ values of pure epoxy and 20% by mass Bi2O3, WO3, and Bi2WO6 doped composites are compared it has been observed that WO3 additive causes higher ε′ values than other additives in the entire frequency region, ignoring the high dielectric loss. However, when ε′ and ε′′ are evaluated together, Bi2O3 and Bi2WO6 additives cause lower dielectric loss than WO3, and higher ε′ values than pure epoxy which make these additives more advantageous than WO3 for energy storage applications. In addition to these examinations, frequency‐dependent phase angle evaluation has also suggested that 30% Bi2O3 and 20% Bi2WO6 additives can be considered promising for energy storage applications in the high‐frequency region.This article is protected by copyright.
