Here, to fabricate an epoxy coating (EP) possessing premier mechanical and thermal features, a nanocomposite of oxidized multiwall nano carbon tube/ ZIF-8 (O-MWCNT@ZIF-8) was prepared through a one-step fabrication approach of ZIF-8 on the O-MWCNT surface through two-different hydrothermal and co-precipitation methods, that are labeled as O-MWCNT-ZIF-8-H/EP and O-MWCNT-ZIF-8-CO/EP, respectively. After introducing the prepared nanocomposite into the epoxy resin, DMTA and tensile tests were applied on the prepared coatings to identify the interactions between the EP/Particles and investigate the resultant thermomechanical properties of the final composites. It was indicated that through the incorporation of 0.15 wt.% of the prepared nanoparticles into the EP matrix, a remarkable enhancement could be achieved on its thermomechanical properties. It is also worth noting that the storage modulus showed a rise of about 7.5% and 1.1% and tensile strength increased about 70% and 40%, while T_g reduced about 12 °C and 16 °C in the case of O-MWCNT-ZIF-8-CO/EP and O-MWCNT-ZIF-8-H/EP samples, respectively, in comparison to the unmodified epoxy (Neat EP) sample. Moreover, the remaining weights of 75% and 77% for O-MWCNT-ZIF-8 compared with 82% for O-MWCNT at 600 °C evidenced the lower thermal stability of the ZIF-8 modified CNT.

在这里，为了制造具有卓越机械和热特性的环氧树脂涂层 (EP)，通过 ZIF-的一步制造方法制备了氧化多壁纳米碳管/ ZIF-8 (O-MWCNT@ZIF-8) 的纳米复合材料。 8 通过两种不同的水热法和共沉淀法在 O-MWCNT 表面上制备，分别标记为 O-MWCNT-ZIF-8-H/EP 和 O-MWCNT-ZIF-8-CO/EP。将制备的纳米复合材料引入环氧树脂后，对制备的涂层进行 DMTA 和拉伸试验，以确定 EP/粒子之间的相互作用，并研究最终复合材料的热机械性能。结果表明，通过将 0.15 wt.% 的制备纳米颗粒掺入 EP 基体中，可以显着提高其热机械性能。_{在 O-MWCNT-ZIF-8-CO /} EP 和 O-MWCNT-ZIF-8-H/EP 样品的情况下，与未改性环氧树脂（Neat EP ） 样本。此外，在 600 °C 下，O-MWCNT-ZIF-8 的剩余重量分别为 75% 和 77%，而 O-MWCNT 的剩余重量为 82%，这证明了 ZIF-8 改性 CNT 的热稳定性较低。
