【摘要】：以石墨烯为代表的二维材料因其原子级厚度、独特物理性质,成为近年来物理、化学、材料交叉学科的研究热点,在合成制备、结构表征、应用开发等方面的研究工作表明其在微纳机电系统、光电器件与功能复合材料领域有广泛且重要的应用前景。然而,由于二维材料结构与尺度的独特性,在其基本物性的理解方面仍存在许多未解决的问题,尤其是力学性能的表征,面临着诸多挑战。本文综述了二维材料本征力学性质和界面力学行为的微纳测试与表征技术的最新进展,例如纳米压痕技术、微孔鼓泡法等,并详细探讨了影响二维材料力学性能及行为的主要因素,分析了其微观尺度下的作用机制,以期通过物理或化学手段实现力学性能的调控。
[Abstract]:Due to its atomic thickness and unique physical properties, graphene as the representative of two-dimensional materials has become a research hotspot in the field of physics, chemistry and materials. The research work in application and development shows that it has a wide and important application prospect in the fields of micro / nano electromechanical systems, optoelectronic devices and functional composites. However, due to the unique structure and scale of two-dimensional materials, There are still many unsolved problems in the understanding of their basic physical properties, especially the characterization of mechanical properties. In this paper, the recent advances in micro-nano measurement and characterization of intrinsic mechanical properties and interfacial mechanical behavior of two-dimensional materials, such as nano-indentation, microcellular bubbling, etc., are reviewed. The main factors affecting the mechanical properties and behavior of two-dimensional materials are discussed in detail, and the mechanism of their action at the micro scale is analyzed in order to realize the regulation of mechanical properties by physical or chemical means.
