The discovery of graphene has triggered a great interest in inorganic as well as molecular two-dimensional (2D) materials. In this review, we summarize recent progress in the mechanical characterization of free-standing 2D materials, such as graphene, hexagonal boron nitride (hBN), transition metal-dichalcogenides, MXenes, black phosphor, carbon nanomembranes (CNMs), 2D polymers, 2D metal organic frameworks (MOFs) and covalent organic frameworks (COFs). Elastic, fracture, bending and interfacial properties of these materials have been determined using a variety of experimental techniques including atomic force microscopy based nanoindentation, in situ tensile/fracture testing, bulge testing, Raman spectroscopy, Brillouin light scattering and buckling-based metrology. Additionally, we address recent advances of 2D materials in a variety of mechanical applications, including resonators, microphones and nanoelectromechanical sensors. With the emphasis on progress and challenges in the mechanical characterization of inorganic and molecular 2D materials, we expect a continuous growth of interest and more systematic experimental work on the mechanics of such ultrathin nanomaterials.

独立的无机和分子二维材料的力学

石墨烯的发现引发了对无机以及分子二维(2D)材料的极大兴趣。在这篇综述中,我们总结了独立2D材料的机械表征的最新进展,这些材料包括石墨烯,六方氮化硼(hBN),过渡金属-二卤化金属,MXenes,黑色荧光粉,碳纳米膜(CNMs),2D聚合物,2D金属有机骨架(MOF)和共价有机骨架(COF)。这些材料的弹性,断裂,弯曲和界面特性已使用多种实验技术确定,包括基于原子力显微镜的纳米压印技术拉伸/断裂测试,凸出测试,拉曼光谱,布里渊光散射和基于屈曲的度量。此外,我们介绍2D材料在各种机械应用中的最新进展,包括谐振器,麦克风和纳米机电传感器。随着对无机和分子2D材料机械表征方面的进展和挑战的重视,我们期望人们对这种超薄纳米材料的力学表现出持续的兴趣和更系统的实验工作。
