纳米级操纵技术是制造纳米级结构、器件的重要方法之一,同时也是研究纳米粒子之间相互作用的重要手段。该文在运用原子力显微镜的探针操纵碳纳米管的同时,开发了一种纳米级操纵力的同步测量方法。应用该方法,成功测量出了操纵、切割碳纳米管的侧向力信息,从而为研究纳米粒子、基体与操纵工具之间的相互作用提供了最直接的力学信息和实验结果。在此基础上,可以进行初步的纳米设计,研究纳米新材料的力学特性。
Nanoscale manipulation technology is one of the important methods to fabricate nano-scale structures and devices, and it is also an important method to study the interaction between nano-particles. In this paper, the use of atomic force microscopy probe manipulation of carbon nanotubes at the same time, developed a nano-level control of the synchronous measurement method. With this method, the lateral force information of manipulating and cutting carbon nanotubes was successfully measured, which provided the most direct mechanical information and experimental results for the study of the interaction between nanoparticles and matrix. On this basis, preliminary nano-design can be carried out to study the mechanical properties of new nanomaterials.
