“…The electrical properties of the TIM can be controlled by changing the type of filler used for making the TIM. Conductive TIM sheets could be obtained if conductive materials (e.g., graphite and metals) are used as fillers. , In contrast, an insulating TIM sheet is obtained using insulating materials (e.g., boron nitride and alumina) as fillers. , This study focuses on the fabrication of conductive TIM sheets, which are easy to handle and can be used for electromagnetic noise shielding.…”

A Ag aerogel-like film (referred to as aerogel hereafter), used as a thermal interface material with enhanced performance and thermal stability, is reported. An aerogel/ foil/aerogel "monocomposite" is created by rapidly forming and depositing Ag nanoparticles on both faces of a Ag foil by the gas-evaporation and particle-deposition method in a few minutes. The monocomposite, having an aerogel of a low packing ratio (<10%) with a clean surface, exhibits low thermal resistance (18 mm 2 K W −1 ) when sandwiched with Cu rods. The monocomposite exhibits excellent thermal stability and significantly reduced thermal resistance (3.0 mm 2 K W −1 ) at 246 °C, keeping its low thermal resistance (2.8 mm 2 K W −1 ) after the temperature is decreased to 51 °C; further, the resistance reduces to 2.1 mm 2 K W −1 after 10 cycles of heating and cooling (100−200 °C). The Ag monocomposite, having high performance comparable to that of the benchmark In sheet and excellent thermal stability at a temperature higher than the melting point of In, will enable high-power and high-temperature operation of computing and power devices.
