Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
Thermal interface materials are used to enhance the contact between two pieces of an electronic, to ultimately reduce the temperature and improve performance. This paper researches the contact resistance of curable polymer gels, a thermal interface material (TIMs). These TIM polymer gels have quite different mechanical properties thanks to the rheology of the polymer itself. Alongside physical testing, the researchers proposed a model to predict the thermal contact resistance of ...
Using the Transient Plane Source technique, various geopolymers, metakaolin-derived sodium (Na), sodium-potassium (NaK) and potassium (K), were tested to determine the effect of varying environmental conditions, such as temperature and humidity, on thermal conductivity. The results concluded that the thermal properties of the geopolymers derived from metakaolin are not greatly affected by the Si/Al ratio in the as-cured state. When the sodium geopolymers were tested at 50% relative humidity, the ...
