| 中文摘要: |
| 采用分子动力学模拟方法研究碳纳米管（CNTs）对顺丁橡胶（BR）摩擦性能的影响。模拟结果表明，与纯BR相比，CNTs/BR复合材料的橡胶分子间作用力和橡胶分子运动空间更小，橡胶分子更稳定，玻璃化温度和刚性更高，摩擦界面温度和摩擦界面橡胶分子运动速度更低，摩擦因数更小，耐磨性能提高。 |
| 英文摘要: |
| The effect of carbon nanotubes（CNTs）on the friction properties of butadiene rubber（BR）was studied using molecular dynamics simulation methods.The simulation results showed that compared with pure BR，CNTs/BR composite had smaller intermolecular forces and movement space of rubber molecules，more stable rubber molecules，higher glass transition temperature and rigidity，lower friction interface temperature and movement speed of rubber molecules at friction interface，smaller friction coefficient，and improved wear resistance. |
