“…Comparing the sample XRD patterns with those simulated from published ZIF-8 structural data, peaks were observed at 7.4°, 10.4°, 12.8°, 14.6°, 16.4°, and 18.1°, indicating the hexagonal structure of the synthesized particles that is consistent with the reports from previous studies. 32,33 Figure 2b shows the thermogravimetric (TGA) curves of ZIF-8 and ZIF-8 encapsulated with different kinds of lubricants. The initial thermal decomposition temperature of pure ZIF-8 is 395 °C (Figure 2b).…”

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.

“…To investigate the curing kinetics of the two curing reactions of 2MI/EP and 2MI-ZIF-8/EP. The DSC scans from 30 °C to 250 °C at four different heating rates (5,10,15,20 °C/min) are shown in Figure 4. As expected, the curing temperature for both 2MI-ZIF-8/EP and 2MI/EP are increased about 25 °C when the heating rate is increased from 5 to 20 °C/min.…”

“…[4] Commonly, the inclusion of nanofillers into the EP has been regarded as one of the most common and efficient approach to build high-performance EP nanocomposites. [5] Various nanofillers such as fullerene, [6] carbon nanotubes [7] and graphene [8] have been selected for this aim. However, these carbon-based nanofillers still suffer from the poor compatibility and uneven dispersion.…”

Rational designing a novel curing agent with high-stability and long storage time is highly attractive but remains a critical challenge. Herein, a novel curing agent (2MI-ZIF-8) is constructed by the Zeolitic Imidazolate Framework-8 (ZIF-8) and 2methylimidazole (2MI). 2MI-ZIF-8 is utilized as a functional nanofiller and curing agent to prepare the 2MI-ZIF-8/EP nanocomposites. The chemical structures of 2MI-ZIF-8/EP were investigated by SEM, XRD, DSC and TG characterizations. The SEM images show that the ZIF-8 particle is individually dispersed in the EP matrix. The DSC results confirm that the curing temperature of the 2MI-ZIF-8/EP is higher than that of 2MI/EP. In addition, the kinetic parameters and the activation energy of the curing reaction were acquired according to the fitting of Kissinger equation and Ozawa equation. This study opens new avenues for the rational design of EP nanocomposites by employing MOFs-based materials as curing agent for wide engineering applications.
