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 ...
The purpose of this study was to measure the thermodynamic properties of 1-hexyl-3-methylimidazolium tetrafluoroborate ([HMIM]BF4) and its graphene-dispersed ionic liquid based nanofluids (Ionanofluids) from room temperature to 200 °C. A thermal analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of [HMIM]BF4 and the GE-dispersed Ionanofluids increased linearly with temperature, and with mass particle fraction. It ...
As electronic devices approach nanometer scales, heat distribution becomes nonuniform and hot spots begin to form. Integrating graphene into nanoelectronics enhances thermal conductivity and heat flow which mitigates hot spots. In this experiment, large quantities of graphene were produced and thermal conductivity was measured by the transient plane source (TPS) method using an instrument. Results showed that the addition of graphene greatly improved the thermal conductivity of the thermal interface ...
In this paper, natural rubber (NR)/graphene (GE) composites were prepared using an ultrasonically-assisted latex mixing and in situ reduction (ULMR) process. A thermal constants analyzer measured the thermal conductivity of the NR/GE composites using the transient plane source (TPS) method. Results showed that GE had a good thermal conductivity, and can be used as a thermal conductivity enhancer in polymers....
The researchers used an instrument to measure the thermal properties (thermal conductivity and specific heat) of anisotropic thermally insulating foams produced by the mixing of nanocellulose, graphene oxide and sepiolite nanorods via the freeze-casting method. These anisotropic foams showed superior thermal properties when compared to expanded polystyrene (a common insulation material), and had a thermal conductivity value of 0.015 W/mK which is half the value for expanded polystyrene. Not only ...
