“…The signal peaks at 709.04 and 711.5 eV indicate that the surface of the carbon steel mainly contains FeCl 2 and Fe 2 O 3 , while the XPS of the F-DN coated carbon steel (Figure S6a) shows signal peaks of Fe, FeO, and Fe 2 O 3 at 705.8, 709.6, and 713.0 eV. 55,56 This suggests that the F-DN coated carbon steel may undergo slight oxidation at this time. From the Raman spectrum of the carbon steel surface (Figure 7e), characteristic peaks of Fe 2 O 3 can be seen at 216 cm −1 , 285 cm −1 , 395 cm −1 , 606 cm −1 , and 1306 cm −1 , while no signal peaks were detected in the Raman spectrum of the F-DN coated carbon steel (Figure S6b).…”

Smart responsive materials are capable of responding to external stimuli and, compared to traditional materials, can be effectively reused and reduce usage costs in applications. However, smart responsive materials often face challenges such as the inability to repair extensive damage, instability in long-term performance, and inapplicability in extreme environments. This study combines 2D diamond nanosheets with organic fluorinated molecules to prepare a smart nanofluid (fluorinated diamond nanosheets, F-DN) with selfhealing and self-adhesion properties. This smart nanofluid can be used to design various coatings for different applications. For example, coatings prepared on textured steel plates using the drop-casting method have excellent superhydrophobic and high oleophobic properties; coatings on titanium alloy plates achieve low friction and wear in the presence of lubricating additives of F-DN in perfluoropolyether (PFPE). Most impressively, coatings on steel plates not only provide effective corrosion resistance but also have the ability to self-heal significant damage (approximately 2 mm in width), withstand extremely low temperatures (−64 °C), and resist long-term corrosion factors (immersion in 3.5 wt % NaCl solution for 35 days). Additionally, it can act as a "coating glue" to repair extensive damage to other corrosion-resistant organic coatings and recover their original protective properties. Therefore, the smart nanofluid developed in this study offers diverse applications and presents new materials system for the future development of smart responsive materials.

To modify the tribological properties of epoxy (EP), additive phases, such as inorganic/organic lubricating fillers, are often introduced to form EP‐based solid‐lubricating composites, which are extensively utilized in industrial sectors like aerospace, automotive, and electronics. The composite methods can be divided into single‐phase composite and multiphase composite. Single‐phase fillers can improve the tribological properties of the composite while the content and distribution of the fillers should be precise controlled. Multiphase fillers offer significant advantages in enhancing the comprehensive properties of EP, making them more suitable for practical harsh environments. This review investigates the progress in research on the tribological properties of EP‐based solid‐lubricating composites and provides an outlook on the future development of lubricating fillers.Highlights In this paper, the commonly used lubricating fillers in EP‐based solid‐lubricating composites and their composite methods, including inorganic and organic fillers, were reviewed. The various EP‐based solid‐lubricating composites, and their lubrication or wear mechanisms were introduced in detail, and the future development directions of the composites were prospected.
