摘要:

本体聚合物的差的导热性可以通过将它们与高导热性材料如碳纳米管组合来增强。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(ACPC)具有高的热导率。分析表明,这种排列结构不仅可以利用碳纳米管的高导热性,而且可以提高聚乙烯(PE)链的导热性。我们的预测可能会激发制造对齐的聚合物基复合材料的各种应用。

英文摘要:

The poor 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 (ACPCs) has a high thermal conductivity by non-equilibrium molecular dynamics simulations. The analyses indicate that the aligned structure can not only take advantage of the high thermal conduction of carbon nanotubes, but enhance thermal conduction of polyethylene (PE) chains. Our predictions may inspire manufacturing aligned polymer-based composites for a wide variety of applications.
