Using few-layer graphene (FLG) flakes the authors are able to create graphene composites (where graphene is a filler) and measure the thermal properties of these composites using a laser flash technique. In some cases, the thermal conductivity was increased by ten times while only using 5 vol.% graphene as filler. Graphene would make a good filler for thermal interface materials....
As electronic devices become smaller, power densities increase and so do hotspot temperatures, leading to a need for materials that can exchange heat better. The materials that facilitate this heat exchange are called thermal interface materials (TIMs). Graphene has been shown to demonstrate superior thermal conductivity and a particular form called few-layer graphene (FLG) was used in this project. A novel TIM was created by the mixing of a silver ...
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 ...
Thermal Interface Materials (TIMs) are used in the field of electronics, to reduce the thermal contact resistance between the heat sink and heat source, to improve heat dissipation within the electronic device. In this experiment, researchers created a TIM by synthesizing Carbon Nano-Tubes (CNTs) on both sides of a thin copper foil. To test the thermal conductivity of the foil with this enhancement, the transient plane source method was employed. ...
The transient plane source method was used to perform thermal conductivity, thermal diffusivity, and specific heat capacity measurements. Thermal transport properties of several thermal greases were characterized using TPS and data were compared to supplier data, received by other methods, to determine accuracy of the TPS method....
