研究了单壁碳纳米管和多壁碳纳米管的热稳定性。对该问题进行了建模和仿真，采用了分子动力学模拟，并结合了开放式和封闭式碳纳米管的Berendsen恒温方案。结果表明，单壁碳纳米管的热稳定性优于多壁碳纳米管。模拟还表明，更短的碳纳米管能够承受更高的热负荷。直径越大的碳纳米管也更能抵抗热载荷。
This paper investigates the thermal stability of single and inulti-walled carbon nanotubes (CNTs). The modeling and simulation of the problem are carried out using molecular dynamics simulation incorporating the Berendsen thermostat scheme for both open-ended and close-capped CNTs. It is found that single-walled CNTs are thermally more stable than multi-walled CNTs. The simulations also indicate that shorter CNTs are able to withstand higher thermal loads. CNTs with a larger diameter are also more resistant to thermal loads.
