“…Therefore, a profound understanding of the reliability of LMAs as TIMs is missing from the literature. Finally, Hamdan et al [13] reported the thermal resistance of liquid mercury micro droplets deposited onto gold plated silicon die is to be as low as 0.00253 cm 2°C /W. However, mercury should be avoided unless its use is absolutely required.…”

“…Greases are the most widely used TIMs and offer thermal resistances in the range of 0.1 to 1 cm 2°C /W [6,12,13]. Chung [14] reported that a polyethylene glycol (PEG) based thermal paste can offer thermal resistance as low as 0.053 cm 2°C /W when mixed with boron nitride.…”

“…Thus, if a certain liquid metal or its alloys with a low melting point are utilized as a thermal interface material, a much higher heat transfer capacity than that of traditional TIMs can be obtained. Hamdan et al present a thermal interface material consisting of an array of mercury microdroplets deposited on a silicon die [14]. The thermal interface resistance was measured as low as 0.235 mm 2 kW −1 .…”

This study reports a gallium-based thermal interface material (GBTIM) consisting of gallium oxides dispersed uniformly into the 99 % gallium metal. The wettability of GBTIM with other materials is disclosed and compared. The thermal conductivity of GBTIM measured by a computer-controlled Mathis TCi thermal analyzer is ∼13.07 W m −1 K −1 at room temperature, which is significantly higher than that of conventional thermal greases. An experimental facility is described to measure the thermal resistance across the GBTIM under steady-state conditions and the thermal interface resistance is measured as low as 2.6 mm 2 kW −1 with a pressure of 0.05 MPa, which is an order lower than that of the best commercialized thermal greases. Further, the GBTIM is formed into a desired shape to enhance thermal transfer, such as semi-liquid paste or thermal pad, which can be cut into a required shape.

“…The oxidation/corrosion can be mitigated by providing a hermetic seal, 17 and the formation of intermetallic compounds can be prevented by using a diffusion barrier coating. 18 Lithium ion (Li-ion) batteries suffer from a high temperature rise during operation due to high energy and power density, thus affecting their life span and efficiency. 19 Paraffin based composites can prevent Li-ion batteries from rising temperature, because it stores heat in the form of sensible and latent heat, mainly in the latent heat form owing to the large latent storage capacity.…”
