Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The purpose of this study was to improve the wettability of silicon carbide (SiC) nanowires, in order for them to be used as thermoconductive fluids. Multiple experiments were conducted by exposing the SiC nanowires to hydrofluoric acid, tetraethyl orthosillicate, polyvinylpyrolidone and sodium hydroxide. Various tests, including x-ray diffraction, Fourier transformation-infrared, x-ray photoelectron spectroscopy, thermogravimetric analysis, scanning electron microscopy and transmission electron microscopy, were performed on these various materials to identify ...
Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. ...
The effects of cooling time on the reproducibility and accuracy of thermal conductivity measurements made using a Thermal Constants Analyzer were evaluated. Selected metal alloys and silicone based electronic interface materials were used for the testing. Cooling times of 30, 15, 10, 5, and 1 minute between measurements were selected, and three measurements were made for each cooling time. These tests were also performed at temperatures of 25, 50, and 70ÂșC to determine if sample temperature had ...
Graphite nanoplatelets were dispersed in varying quantities into a silicone matrix to form composite materials with higher thermal conductivities than the pure silicone matrix without sacrificing mechanical properties. It was found that the thermal conductivities of the composites increased with increasing GNP content as well as with increasing GNP particle size. The composites were found to be effectively electrically insulating, and it was found that the addition of GNP did ...
Preventing steel from losing its strength during fires is crucial for safe evacuation and effective fire fighting. One of the most common protective coatings applied to steel and other construction materials today is intumescent paint. In this study, researchers created a potential new protective coating using a curable silicone base and varying volume amounts of expandable graphite between 5-25%. The key characteristic of these coatings is that they swell to ...
