Abstract:
Carbon nanotubes are a promising candidate for the application of flexible electronics due to the ultrahigh intrinsic conductivity and excellent mechanical flexibility. In the present work, the morphology of the ultrathin (diameter<20 nm) multi-walled carbon nanotubes (MWCNTs) under an axial compression was investigated by using in-situ transmission electron microscopy. Moreover, the overall dynamic deformation processes and the force-displacement (F-D) curves of the MWCNTs were also examined. Interestingly, the MWCNTs almost restored their original morphology after 15 loading-unloading cycles. The deformation and recovery process indicate that the MWCNTs are flexible and exhibit excellent durability against compression. The Young’s modulus of the MWCNTs is estimated with the value of ∽0.655 TPa derived from the F-D curves fitting. Our results suggest that the ultrathin carbon nanotube structures may have great application potentials in flexible devices.

摘要:
本文利用原位透射电子显微镜技术,研究了单根超细(直径<20 nm)多壁碳纳米管(MWCNT)在轴向载荷下形貌和结构的演化过程,并对同步获取的多壁碳纳米管力-位移(F-D)曲线进行了分析. 有趣的是,经历过15次轴向压缩循环后,MWCNT在形貌和结构上都几乎保留了原始形态. 大尺寸的弹性形变过程表明,碳纳米管具有良好的柔韧性和抗压缩性能. 根据F-D曲线拟合得出的碳纳米管的杨氏模量约为0.655 TPa.
