随着现代电子设备对改进的热管理解决方案的需求不断增加，碳纳米管（CNT）已被建议作为热界面材料（TIM）的候选材料。然而，由于界面处的弱相互作用，碳纳米管与匹配衬底之间的界面电阻是巨大的。在化学功能化的帮助下，这些材料可以在TIM应用中充分发挥其潜力。通过利用基于环氧硅烷的单层，可以在CNT和目标衬底之间获得共价锚定，以便桥接界面，否则，会出现高电阻。为了使CNT阵列适应环氧化学，CNT随后经受氮等离子体以用氨基活化它们。测量了热界面，发现与参考样品相比，热阻降低了5%。
With the ever increasing demand for improved thermal management solutions in modern electronic devices, carbon nanotubes (CNTs) have been suggested as a candidate material for thermal interface materials (TIMs). However, the interfacial resistance between CNTs and matching substrate is huge due to poor interaction at the interface. With the help of chemical functionalization, these materials can be exploited to their full potential in TIM applications. By utilizing the epoxy-silane-based monolayers, covalent anchoring can be obtained between the CNTs and target substrate in order to bridge the interface, where high resistances, otherwise, would arise. To adapt CNT arrays to the epoxy chemistry, the CNTs have subsequently been subjected to nitrogen plasma in order to activate them with amino groups. The thermal interfaces were measured, and the thermal resistance was found to be decreased by 5% in comparison with the reference samples.
