Effect of graphite fillers on electrical and thermal conductivity in epoxy-based composites: Percolation behavior and analysis
Original language description
This work investigated a method for producing epoxy-based composites using various graphite fillers, such as natural, synthetic, and thermally expanded graphite. The study aimed to determine the impact of the filler type, size, and volume fraction on the composites’ thermal and electrical conductivity. Results indicate that the percolation model accurately represents electrical and thermal conductivity behavior, with graphite fillers forming conductive clusters in the polymer matrix. The percolation threshold for electrical conductivity varies between 2.8 and 8.5 vol.%, while for thermal conductivity, it ranges from 5.0 to 18.0 vol.%. This is due to both the electron transfer tunneling effect and the necessity of higher filler content to facilitating effective phonon transport. Understanding percolation behavior facilitates the prediction and optimization of composites with specific electrical and thermal properties for diverse applications.
