This paper discusses the fundamental issues of the elastic properties and effective wall thickness of single-walled carbon nanotubes (SWCNTs). It provides an in-depth analysis based on the rationale of the nanoscale-to-macroscale deformation relationship of SWCNTs and carries out a critical assessment of the diverse theoretical predictions in the literature. It was found that the in-plane stiffness of SWCNTs is a mechanics quantity that has been consistently reflected by the majority of the existing models. However, a further systematic study is necessary to clarify the dilemma of the wall thickness of SWCNTs.
本文讨论了单壁碳纳米管（SWCNTs）的弹性特性和有效壁厚的基本问题。基于SWCNTs从纳米尺度到宏观尺度变形关系的原理进行了深入分析，并对文献中各种理论预测进行了批判性评估。研究发现，SWCNTs的面内刚度是大多数现有模型一直反映的力学量。然而，有必要进行进一步的系统研究，以厘清SWCNTs壁厚方面的困境。
