Stability of interface between MgO and carbon nanotubes

  • 摘要: 采用共沉积法制备氧化镁纳米颗粒包覆碳纳米管,并利用高功率超声波、长时间对氧化镁包覆碳纳米管样品进行超声处理以验证其结构稳定性。借助红外光谱仪、扫描电子显微镜和透射电子显微镜表征氧化镁包覆碳纳米管的微观结构。实验结果显示:高功率超声波和长时间超声震荡可将包覆氧化镁碳纳米管切断,但氧化镁纳米颗粒依然紧紧地吸附在碳纳米管管壁上,表明氧化镁纳米颗粒与碳纳米管形成了良好的界面结合,包覆MgO碳纳米管界面结构具有较高的稳定性,是一种较好的新型增强体。同时,采用第一性原理计算阐述了氧化镁与碳纳米管形成良好界面结合机理。
