“…The lubricants being encapsulated in the ZIF-8 are released under pressure after the friction and wear. The lubricant adheres to the polymer and the counterface material to form a complete and stable lubrication film, reducing the coefficient of friction and wear rate . On the other hand, the size of our prepared ZIF-8 is 50 nm (Figure ) and has a large surface area.…”

“…The lubricant adheres to the polymer and the counterface material to form a complete and stable lubrication film, reducing the coefficient of friction and wear rate. 37 On the other hand, the size of our prepared ZIF-8 is 50 nm (Figure 3) and has a large surface area. In the process of friction, the nanomaterial fragments can strengthen the adhesion of wear fragments to the surface of the counterface material, thus improving the performance of the lubrication film.…”

Zeolitic imidazolate framework-8 (ZIF-8) was fabricated as a lubrication container to encapsulate lubrication oil, which was added to epoxy resin (EP) as a filler to get the self-lubricating ZIF-8/EP composites coating. The antiwear and anticorrosion peculiarities of EP can be significantly improved by the encapsulation method. The antiwear peculiarities of EP were evaluated by the macroscopic ball-disk friction tests with the 9Cr18 steel ball as the counterface material. The result demonstrates that the coefficient of friction (COF) and wear rate of the self-lubricating ZIF-8/EP composites were reduced by 82.1% and 93.5% compared with that of the pure EP, respectively. Importantly, the ZIF-8/ EP composite shows anticorrosion performance in the artificial seawater (ASW). The constant phase element and effective capacitance of the coating containing ZIF-8 fillers are lower than that of the non-containing coating. In addition, the diameter of the capacitive arc and the impedance modulus of the coating containing ZIF-8 + YR1800 are higher than those of the coating non-containing, which proved that the corrosion resistance of the EP is improved by the ZIF-8 + YR1800.
