碳纳米管（CNT）具有非常高的固有热导率，并且预期用于各种热应用中。然而，CNT和周围材料之间的接触热阻（TCR）仍然不清楚。一些分析和分子动力学研究已经报道，但没有可靠的实验方法来定量研究的界面问题。本文报道了一种新的技术，通过使用铂热膜传感器测量单个CNT末端的TCR。介绍了两种获得多壁碳纳米管和SiO2表面之间TCR的方法，并证实两种方法得到相同的TCR。
A carbon nanotube (CNT) has a very high intrinsic thermal conductivity and is expected to be used in a variety of thermal applications. However, the thermal contact resistance (TCR) between a CNT and ambient material still remains unclear. Some analytical and molecular dynamics studies have been reported, but there is no reliable experimental method to quantitatively investigate the interface issues. This article reports on a new technique for measuring the TCR at the end of an individual CNT by using a platinum hot film sensor. Two methods are introduced to obtain the TCR between a multi-walled CNT and a SiO2surface, and both methods were confirmed to give an identical TCR.
