الوصف: It can be inferred from the existing frictional energy dissipation mechanism that metal-organic frameworks (MOFs) may be an ideal material to achieve the solid superlubricity, which is an essential pathway in the energy efficiency. In this work, five MOFs with square grid structure are synthesized, namely Cu(1,4-BDC)(DMF), Cu(1,4-NDC)(DMF), Cu(2,6-NDC)(DMF), Co(1,4-BDC)(DMF) and Zn(1,4-BDC)(DMF), and the superlubricity can be achieved on all of these surface (friction coefficient as low as 5.3 * 10−4). Through experiments and DFT simulation, the realization of superlubricity is attributed to two aspects: firstly, the hybrid inorganic-organic structure of MOFs eliminates puckering effect in topographic factors; secondly, the interaction between probe and MOFs is anchoring effect that is so weak as physical adsorption. The anchoring effect is closely related to the structure unit of MOFs that helps us establish the structure-function relationship. When metal nodes and ligands are selected according to the crystal field theory, the friction performance will be optimal for MOFs with the stable coordination. Moreover, the friction performance of MOFs is predictable that gives MOFs great potential in energy conservation.
