我们已经生产了纳米管在油悬浮液和测量其有效的热导率。测得的热导率是非常大于理论预测，是非线性的纳米管负载。这些反常现象表明了传统的固/液悬浮液热传导模型的基本局限性。我们提出了理解纳米管悬浮液的异常热行为的物理概念。与分散在流体中的其他纳米结构材料相比，纳米管提供了最高的热导率增强，为纳米管的广泛应用打开了大门。(C)2001年美国物理学会。
We have produced nanotube-in-oil suspensions and measured their effective thermal conductivity. The measured thermal conductivity is anomalously greater than theoretical predictions and is nonlinear with nanotube loadings. The anomalous phenomena show the fundamental limits of conventional heat conduction models for solid/liquid suspensions. We have suggested physical concepts for understanding the anomalous thermal behavior of nanotube suspensions. In comparison with other nanostructured materials dispersed in fluids, the nanotubes provide the highest thermal conductivity enhancement, opening the door to a wide range of nanotube applications.
