Dielectric properties play a crucial role in the performance of micro-composites used in various applications such as flexible electronics and energy storage devices. This study focuses on investigating the dielectric properties of micro-composites based on acrylic coated conducting carbon particles embedded in a silicone elastomer matrix. The acrylic coating enhances the dispersion and compatibility of the conducting carbon particles within the silicone elastomer, ensuring uniform distribution throughout the matrix. The dielectric properties, including the dielectric constant and loss tangent, are characterized over a range of frequencies and temperatures. The results reveal the tunability of the dielectric constant by adjusting the filler loading and coating thickness, enabling tailored electrical properties of the micro-composites. The low loss tangent indicates minimal energy dissipation and suggests the suitability of these micro-composites for applications requiring efficient dielectric materials.
