At the interfaces of 2D materials, the solid-state condensed matter physics is closely intertwined with the mechanics in terms of adhesion/separation and friction as well as deformation of 2D materials. With atomically thin 2D layers in atomically close proximity, the chemical, physical, and mechanical interactions simultaneously evolve and influence each other, leading to a wide range of topological structures and properties across nano- and micro-scales. Can the study on the mechanics of interfaces help to understand the physics and chemistry at the interfaces of 2D materials or vice versa? This Opinion aims to highlight the recent mechanics research on such material interfaces, where a multiscale, multidisciplinary effort is most effective moving forward with plenty of challenges and opportunities.

在2D材料的界面上，固态凝聚物的物理特性在2D材料的附着/分离和摩擦以及变形方面与力学紧密相关。随着原子上薄薄的2D层在原子上非常接近，化学，物理和机械相互作用同时发展并相互影响，从而导致纳米级和微米级的各种拓扑结构和特性。对界面力学的研究是否可以帮助理解2D材料界面的物理和化学，反之亦然？本意见旨在强调对此类材料界面的最新力学研究，在这种研究中，多尺度，多学科的努力是最有效的前进，面临着众多挑战和机遇。
