Using a three-roll mill process, graphite nanoplatelets (GNPs) were dispersed in a silicone polymer for application as a thermal interface material. Through the use of electron microscopy and XRD, the researchers were able to determine that the GNPs dispersed better when using the three-roll milling process as compared to previously used methods. GNPs were mixed with the silicone polymer in wt.% up to 25, with the highest wt.% yielding the highest ...

In the electronic industry, manufacturers depend on accurate thermal conductivity testing methods to characterize their new products, and perform quality control maintenance on continuing materials. This paper assesses the ability of the Transient Plane Source (TPS) technique to accurately characterize newly developed materials, for their use in novel electronic applications. Using the TPS technique, various silicone based electronic materials, of differing filler contents, were thermally characterized and examined for their ...

In the building and construction industry today, weather resistant and flame resistant materials have become fundamental. As such, silicone coated materials have been intensively researched, as they increase a given materials resistivity to heat and flames. Due to complications and time constraints when testing coating technologies in a lab setting, more enforcement has been placed on numerical methods. Based on stitching patterns, geometry models of the material and heat transfer ...

In this article, researchers employed the use of the TPS method to test the thermal conductivities of various liquid materials, including mercury and silicone oils of different viscosities, in short-duration microgravity environments. The data received for the lower viscosity silicone liquids displayed extreme effects of thermal convection in the microgravity, as compared to the higher viscosity silicone liquids. When mercury was exposed to the microgravity environment, the thermal conductivity was ...

This research paper delves into the thermal conductivity monitoring of silicone-based electronic materials with various fillers, using the Transient Plane Source (TPS) technique. Aside from the results, researchers also highlight the main features of the TPS technique: a rapid, precise and non-invasive method for measuring thermal properties of various materials. The results received using the TPS technique match those received using other techniques, however when using the TPS technique 30 tests ...
