Tunable thermal conduction character of graphite-nanosheets-enhanced composite phase change materials via cooling rate control

Thermal energy storage (TES) is incredibly important to expanding the field of renewable energy. In this study, the authors look at the potential of composite phase change materials (PCMs) for use in this application. A ball milling method was used to exfoliate expanded graphite in nanosheets that could be added to eicosane to create composite materials. Composites with nanosheets of various sizes were created, and the effect of cooling rate on their thermal conductivity was studied. As the cooling rate was raised, the thermal conductivity of pure eicosane slightly decreased. However, for a composite containing 1 wt% graphite, the thermal conductivity decreased by 25%, indicating that the composites were much more sensitive. Thermal conductivity measurements on the composites themselves showed that larger graphite sheets had a bigger impact on the thermal conductivity enhancement, the highest value recorded with 1.57 W/mK in a composite with 5 wt% loading of larger nanosheets. A percolation threshold was observed around 1 wt% in all samples, otherwise the thermal conductivity increased linearly with filler loading. Upon completion of this research the authors concluded that composite PCMs are a solution for extensive TES applications

Thermal conductivity enhancement of epoxy adhesive using graphene sheets as additives

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 TPS 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.
