New Mechanical Effects of Nano-Materials and Structures at Micro-Nano Scale
Introduction
The heterostructure can be formed by the combination of graphene and one or more of two-dimensional materials. Heterostructures can not only overcome the inherent limitations of each material, but also achieve new properties through their proper combination. However, by van der Waals force stacking, covalent bond splicing and domain-like heterostructures, defects are prone to occur. The existence of these externally introduced defects and intrinsic defects affect the mechanical, thermal and electrical properties of graphene and its heterostructures. Therefore, how to recognize the characteristics of these defects and how to use and control them is very important. Graphene has a special two-dimensional planar honeycomb structure and excellent performance, and is regarded as an ideal reinforcement for metal matrix composites. In particular, the structural diversity and interconvertible characteristics of graphene provide a rich way for the configuration design of metal-based nanomaterials. In this paper, through the combination of theoretical analysis and computer simulation, the graphene / boron nitride heterostructure and its defect mechanical and thermal properties are studied. On this basis, through experiments and molecular dynamics simulation, the design ideas of "internal configuration" and "external multi configuration" of nano materials are proposed, which can be used as an effective means to control the interface structure, load transfer and mechanical properties of metal materials. It is helpful for us to understand the physical mechanism of low-dimensional structure and property correlation, realize multiple structural forms, and even explore new uses.
