Researchers are currently developing ways to produce thermoelectric materials, such as skutterudites, with low lattice thermal conductivity. In this paper, a hydrothermal synthesis procedure was developed to fabricate CoSb3 compounds. A thermal constant analyzer measured the thermal conductivity of three CoSb3 samples using the transient plane source (TPS) method. Results showed that thermal conductivity increased with decreasing temperature, and was much lower for the hydrothermal-synthesized CoSb3 samples than other fabrication ...
In this paper, the simplified hot-plate method (SHOP) measured the thermal conductivity of a prototype instrument, and artificial neural networks (ANNs) were employed to confirm the results. The goal of this paper was to produce ANNs to calibrate and improve the accuracy of SHOP thermal conductivity measurements. A thermal constants analyzer verified the results of the SHOP by measuring the thermal conductivity of plywood and calcium silicate boards using the ...
The purpose of this this study was to graft polymer chains onto the surface of carbon nanotubes (CNTs) to examine the morphology and thermal properties of the epoxy composites in comparison to multiwalled carbon nanotubes (MWCNTs). A thermal analyzer measured the thermal conductivity of the nanocomposites using the transient plane source (TPS) technique. Results showed that the addition of Glycidyl methacrylate (GMA) to the MWCNTs/epoxy composites significantly enhanced thermal ...
In this study, aluminum nitride was treated with silane in an attempt to improve the performance of polyetherimide (PEI) composites. Various properties of the modified AlN/PEI composites were examined including the thermal conductivity by way of a thermal analyzer based on the transient plane source (TPS) method. Results showed that the AlN filler improved dispersion and interface of the matrix which enhanced the thermal conductivity of the PEI composites....
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 ...
