我们使用经典的分子动力学模拟来研究碳纳米管和辛烷液体之间的界面热阻。我们发现一个大的值的界面电阻与刚性管结构和软有机液体之间的弱耦合。我们的模拟演示了软振动模式的热流机制中发挥的关键作用。这些结果表明，碳纳米管聚合物复合材料和有机悬浮液的热导率将受到界面热阻的限制，并与最近的实验是一致的。(C)2004年，美国物理学会。
We use classical molecular dynamics simulations to study the interfacial resistance for heat flow between a carbon nanotube and octane liquid. We find a large value of the interfacial resistance associated with weak coupling between the rigid tube structure and the soft organic liquid. Our simulation demonstrates the key role played by the soft vibration modes in the mechanism of the heat flow. These results imply that the thermal conductivity of carbon-nanotube polymer composites and organic suspensions will be limited by the interface thermal resistance and are consistent with recent experiments.
