【摘要】：碳纳米管、石墨烯和六方氮化硼等低维材料具有优异的力学和电学性质,已经引起广泛的科学兴趣.然而由电荷、分子轨道、电子结构和自旋态构成的低维材料的局域场与力学变形、机械运动和物理化学环境等外场间往往存在强烈耦合,这导致低维材料会呈现出新颖独特的物理力学性能.论文对近年来碳纳米管、石墨烯和六方氮化硼等低维材料的力学性能、力电耦合与器件原理、表面和界面结构性能调控、层间相互作用、能量耗散和摩擦等物理力学方面的研究进展进行了简要综述,并讨论了利用低维材料多场耦合特性和结构性能关联发展新型功能器件的方法和途径,以及纳米力学和纳尺度物理力学的前沿和发展趋势.
[Abstract]:Low dimensional materials, such as carbon nanotubes, graphene and six square boron nitride, have excellent mechanical and electrical properties, which have aroused extensive scientific interest. However, there are often strong coupling between the local field and mechanical deformation of low dimensional materials consisting of charge, molecular orbitals, electronic structures and spin states, mechanical and physical chemical environments. This leads to the new and unique physical and mechanical properties of low dimensional materials. The recent advances in the mechanical properties of carbon nanotubes, Shi Moxi and six square boron nitride, such as mechanical properties, mechanical and electrical coupling and device principles, surface and interfacial structural performance regulation, interlayer interaction, energy dissipation and friction are progressing in the research progress. The methods and approaches to develop new functional devices using the multi field coupling and structural properties of low dimensional materials, as well as the frontiers and trends of nanoscale and nanoscale physical mechanics are discussed.
