Performance and testing of thermal interface materials
The increasing power and reduced die size of CPUs used in computers increases a need for significantly improved thermal interface materials (TIM). The TIM is used to reduce contact resistance at the CPU-heat sink interface. This work provides a state-of-the-art assessment on “thermal interface materials,” including fundamentals, materials used, their performance, and how interface resistance is...
متن کاملEnhancement of thermal interface materials with carbon nanotube arrays
This paper describes an experimental study of thermal contact conductance enhancement enabled by carbon nanotube (CNT) arrays synthesized directly on silicon wafers using plasma-enhanced chemical vapor deposition. Testing based on the one-dimensional reference bar method occurred in a high-vacuum environment with radiation shielding, and temperature measurements were made with an infrared camer...

Title of Document: EVALUATION OF THERMAL INTERFACE MATERIALS AND THE LASER FLASH METHOD Vinh Khuu, Doctor of Philosophy, 2009 Directed By: Chair Professor, Michael Pecht, Department of Mechanical Engineering Thermal interface materials (TIMs) are used to reduce the interfacial thermal resistance between the chip and the heat sink, which has become a bottleneck to heat removal in a variety of el...
متن کاملGraphene-multilayer graphene nanocomposites as highly efficient thermal interface materials.
We found that the optimized mixture of graphene and multilayer graphene, produced by the high-yield inexpensive liquid-phase-exfoliation technique, can lead to an extremely strong enhancement of the cross-plane thermal conductivity K of the composite. The "laser flash" measurements revealed a record-high enhancement of K by 2300% in the graphene-based polymer at the filler loading fraction f = ...
متن کاملThermal properties of graphene and multilayer graphene: Applications in thermal interface materials
thermal interface materials. It has been demonstrated that addition of an optimized mixture of graphene and multilayer graphene to the composites with different matrix materials produces the record-high enhancement of the effective thermal conductivity at the small filler loading fraction (fr10 vol%). The thermal conductivity enhancement due to the presence of graphene in the composites has bee...
