Synthesis of Carbon Dielectric Composite from Candlenut Shell (Aleurites moluccana)

Dielectric materials have attracted attention cause their potential applications such as energy storage devices and sensors. The biggest issues in the synthesis of dielectric materials reside in improving dielectric properties. In our work, a carbon dielectric composite material was successfully synthesized with PEG 4000 and PEG 6000 matrices respectively. The dielectric properties of candlenut shell carbon based composites filled with PEG 4000 and PEG 6000 were investigated. Conductivity of carbon decreases along with the addition of the matrices. The lowest conductivity value was obtained from Carbon / PEG 6000 material (0.52 – 0.91) x 10⁻⁸ S / cm in the measurement range of 10³ Hz - 10⁴ Hz. This is due to the small carbon porosity (33.14%) and the addition of the matrices causing a decrease in the reactive surface area of the carbon.
