Polyoxymethylene (POM) is a resistant polymer with wide applications in aerospace, automotives, and biomedicine. However, it falls short when used in the manufacturing of sliding parts. In this study, copper particles and polytetrafluoroethylene (PTFE) powder were incorporated into POM to improve the thermal conductivity of the polymer composite while reducing the friction coefficient. A thermal analyzer was used to measure the thermal conductivity of POM composites using the transient plane ...
In this study, the thermal properties of stainless steel, ceramic, and silica aerogels were numerically calculated and then compared to actual test results. A thermal constants analyser measured the thermal conductivities and thermal diffusivities of the samples using the transient plane source (TPS) method. Results showed that the values generated by the numerical simulation were within ±3% of the TPS method values, which verifies the reliability and accuracy of the numerical ...
As technology advances, improving the efficiency of heat dissipation by thermal adhesives in electronic devices is becoming increasingly important. In this study, a thermal constants analyzer measured the thermal conductivities of eight different epoxy resin thermal adhesives using the transient plane source (TPS) method. Results showed that the layer-structure fillers enhanced the thermal conductivity of the epoxy matrix the most, while the sharp corner-shaped fillers had the lowest impact on ...
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 propose an improvement in the theory of the transient plane source (TPS) technique. They claim that Gustafsson has ignored the contribution of the electrical resistance charge of the nickel double spiral and the heat capacity of the polyimide film surrounding the nickel spiral. The researchers developed improved mathematical equations to supposedly improve the accuracy of the technique by 1.8 to 2.3%....
