碳纳米管弹性模量的研究

Research on the Elastic Modulus of the Carbon Nanotubes

本文从精巧的实验测量和独到的理论计算两方面对碳纳米管杨氏弹性模量的研究方法、实验原理、基本理论、主要发现及意义等进行讨论。实验测量方法主要包括 CNTs 自由端振动法、AFM 探针偏折或拉伸 CNTs 等;理论计算方法主要涉及到连续体模型,分子动力学模拟或两者相结合的混合方法。

In this paper, the research methods, experimental principles, fundamental theories, main findings, and implications for Young's modulus research of CNTs were reviewed and discoursed from both the ingeniously experimental measurements and distinctively theoretical calculations. The experimental measurements include the methods of vibration at CNT's free ends, and the CNTs bending or stretching with AFM tip(s). The continuum mechanical method, molecular-dynamics stimulation, and the mixture of both methods are involved in the theoretical calculations.
