通过将本体聚合物与高导热材料如碳纳米管相结合，可以增强其超低的导热系数。与随机掺杂不同，通过非平衡分子动力学模拟发现，定向碳纳米管-聚乙烯复合材料具有较高的导热系数。分析表明，这种定向复合材料不仅利用了碳纳米管的高导热性能，而且增强了聚乙烯链的导热性能。
The ultra-low thermal conductivity of bulk polymers may be enhanced by combining them with high thermal conductivity materials such as carbon nanotubes. Different from random doping, we find that the aligned carbon nanotube-polyethylene composites has a high thermal conductivity by non-equilibrium molecular dynamics simulations. The analyses indicate that the aligned composite not only take advantage of the high thermal conduction of carbon nanotubes, but enhance thermal conduction of polyethylene chains.
