Carbon Nanotube Arrays as Thermal Interface Materials

摘要

Carbon nanotube (CNT) arrays can be used as a thermal interface materials (TIMs). Using a phase sensitive transient thermo-reflectance (PSTTR) technique, the thermal conductance of the two interfaces on either side of the CNT arrays can be measured. The physically bonded interface has a conductance ˜10⁵ W/m²-K and is the dominant resistance. Also by bonding CNTs to target surfaces using indium, it can be demonstrated that the conductance can be increased to ˜10⁶ W/m²-K making it attractive as a thermal interface material (TIM).
