摘　　要：利用分子动力学和第一原理计算方法,对3种典型金属纳米颗粒在碳纳米管表面的浸润过程进行了建模分析.结果表明,金属纳米颗粒在较低的温度即可融化,并对碳纳米管表面浸润,其浸润能力取决于碳纳米管对金属原子的吸附力和金属原子之间的吸引力,两者之间的力差决定了不同类型金属原子对碳纳米管表面的浸润特性.The wetting process of the three typical metal nanoparticles on the surface of carbon nanotubes was simulated by molecular dynamics and the first principle calculation method.The results showed that the metal nanoparticles could melt at a lower temperature and wet the surface of the carbon nanotubes.Its wetting capacity depended on the adsorption force of carbon nanotubes on the metal atoms and the attraction force among metal atoms,and the force difference determined the wetting characteristics.
