Metal-organic framework (MOF) nanoparticles have attracted widespread attention as lubrication additives due to their tunable structures and surface effects. However, solid properties been rarely explored. This work introduces the positive role of moisture in case a newly described Ti-based MOF (COK-47) powder. COK-47 achieves an 8.5-fold friction reduction compared AISI 304 steel-on-steel sliding under room air. In addition, maintains similarly low coefficient (0.1-0.2) on various counterbodies, including Al2O3, ZrO2, SiC, Si3N4. Notably, other widely studied MOFs (ZIF-8, ZIF-67) 2D materials powder (MXene, TMD, rGO), exhibits lowest (≈0.1) same experimental settings. Raman spectroscopy, X-ray diffraction, photoelectron energy dispersive scanning electron microscope, transmission microscopy indicate that tribofilm is amorphous film obtained by hydrolysis air with moisture. Density functional theory further confirms water catalyzes decomposition COK-47, crucial step forming tribofilm. study demonstrates idea utilizing water-assisted mechanisms. It provides new insights into applications tribology highlights interdisciplinary contributions mechanical engineering chemistry.

Abstract Corrosion and fouling problems are two main challenges for devices working in the ocean. However, most existing solutions lack ability to concurrently obtain corrosion resistance antifouling behavior. Here, a novel waterborne epoxy (WEP) based composite coating that has remarkable is developed. The WEP‐based consists of nanohybrid filler prepared by loading silver (Ag) nanoparticles on graphite nanoplatelets (GNP) surface through facile situ hydrothermal synthesis polydopamine (PDA) modification.

High-temperature-resistant and self-lubricating polymer composites with long life high reliability are increasingly indispensable in the aerospace field. Herein, ZIF-67 grown on MXene lamella was successfully prepared, ZIF-67@MXene/PI a regular layered structure were obtained by hot-pressing three-dimensional network aerogel. It revealed that incorporating ZIF-67@MXene into PI dramatically reduced friction abrasion elevated temperatures. Largely, aerogel walls always paralleled sliding direction compressing, providing significant antifriction effect. More notably, presence of vigorous tribofilm composed matrix diamond-type lattice MOF-modified provided rolling interface under temperatures, simultaneously. In addition, uniform thickness about 200 nm can effectively avoid direct contact pair during process. Hence, combination constructed multiscale nanocomposites nanostructured outstanding tribological performance endow material potentially useful reducing energy consumption, thus addressing wastage problem caused friction.
