摘要
二硫化钼(MoS2)作为一种力学性能优异的典型二维半导体材料,成为制备柔性电子器件的最佳材料之一,同时其层间结合力相对较弱,也是润滑减摩的理想材料.二维材料的结构特性和受载下的力学行为对其服役寿命和摩擦学表现有直接影响.本文系统回顾了二维MoS2 原位力学性能和摩擦学性能的理论模拟和实验研究.首先关注了MoS2在纳米压痕过程的弹塑性变形和断裂失效行为,以及缺陷对MoS2机械可靠性的影响,梳理了基于原子力显微镜的原位测试方法的优势和局限.其次,探讨了温度、气氛、湿度和晶格取向等因素对MoS2表面摩擦及层间剪切的影响,并对MoS2作为润滑添加剂在工程应用领域实现宏观尺度减摩润滑的研究现状进行了总结与展望.
Abstract
As a typical two-dimensional semiconductor material with excellent mechanical properties,two-dimensional molybdenum disulphide(MoS2)is considered as one of the best candidates for flexible electronic device applications,while its relatively weak interlayer bonding also makes it an excellent lubricant and friction-reducing material.The struc-tural properties and mechanical behavior of 2D materials under load have a direct impact on their service life and tribo-logical performance.This paper systematically reviewed the theoretical simulations and the experimental research on in-situ mechanical properties and tribological performance of two-dimensional MoS2.Firstly,the studies on the elastic-plas-tic deformation and fracture failure behavior of MoS2 during the nanoindentation process were concerned,and the effect of defects on the mechanical reliability of MoS2 was mentioned.The advantages and limitations of in-situ testing methods based on atomic force microscopes were also summarized.Secondly,the impacts of temperature,atmosphere,humidity,and lattice orientation on the surface friction and the interlaminar shear of MoS2 were discussed.The current research sta-tus and future prospects of MoS2 as a lubricant additive to achieve macro-scale friction reduction and lubrication in engi-neering applications were summarized.
