Abstract: In this study, various filler loadings of thin graphite sheets were added to epoxy adhesives to improve thermal conductivity. Natural graphite powder and graphite nanoflakes were used as reference fillers in the same resin, and the thermal conductivity of each filler was measured with a Hot Disk TPS-2500 thermal constants analyzer based on the transient plane source (TPS) method. Results showed that the graphene sheets enhanced the thermal conductivity by more than 22 times compared to pure resin, which was higher than any other graphite filler material.
