Epoxy resins are the most prominent thermoset material, which has been extensively applied in a diversity of industries including aerospace, coatings, electronics, and biomedical systems. Due to the shortcomings of epoxy, the desire to use nanocomposites has been increased and become a hot research topic. The GO and MOF-filled composites, due to their fantastic mechanical, thermal, and barrier characteristics, have provided crucial insights for decades. Additionally, although the inherent defects of GO and MOF particles have vastly bounded their constructive applications, presently, the GO-modified MOF particles have been prospered. The mixture of the porous MOFs and GO nanosheets reinforces the physicochemical properties that enable them to be used in a wide range of fundamental technologies. We will entirely summarize the recent advances of MOFs decorated GO nanohybrids in the epoxy resin, and their effects on the constructed composite coating's mechanical & thermal, anti-corrosion, and flame-diminishing properties. Reports evidenced that the introduction of GO and MOF-based nanohybrids into Epoxy resin has provided central insights for decades because of their outstanding mechanical, thermal, and barrier characteristics. The plus and minus of GO and MOF nanofillers can be avoided and boosted by modification of GO via MOFs, respectively. A high reduction of peak heat release rate (p-HRR) up to 41% and the total smoke production decrement up to 30% were reported by the addition of GO-MOF nanohybrids to the EP in comparing with GO-EP nanocomposite, proving the improvement of the flame-retardant properties of epoxy resin. Through screening the literature it is obvious that through the introduction of GO/Ln-MOF nanoparticles into Epoxy resin the anti-corrosion stability of the epoxy resin was greatly improved and reached the 500% level. The adhesion strengths were enhanced up to 100%. In addition, the storage modulus ratio improvement percentile would be about 20% and the energy at the breakpoint was improved by 275%.

金属有机骨架装饰氧化石墨烯(MOFs-GO)纳米建筑应用在环氧涂层机械-热/阻燃和防腐性能改进方面的最新进展

环氧树脂是最突出的热固性材料,已广泛应用于航空航天、涂料、电子和生物医学系统等多个行业。由于环氧树脂的缺点,使用纳米复合材料的愿望增加并成为一个热门的研究课题。GO 和 MOF 填充的复合材料由于其出色的机械、热和阻隔特性,几十年来提供了重要的见解。此外,虽然 GO 和 MOF 粒子的固有缺陷极大地限制了它们的建设性应用,但目前,GO 改性的 MOF 粒子已经蓬勃发展。多孔 MOF 和 GO 纳米片的混合物增强了物理化学性质,使它们能够用于广泛的基础技术。我们将全面总结 MOFs 在环氧树脂中修饰的 GO 纳米杂化物的最新进展,以及它们对构建的复合涂层的机械和热、防腐和阻燃性能的影响。报告证明,将基于 GO 和 MOF 的纳米杂化物引入环氧树脂已提供了几十年来的核心见解,因为它们具有出色的机械、热和阻隔特性。GO 和 MOF 纳米填料的正负可以分别通过 MOF 修饰 GO 来避免和增强。与 GO-EP 纳米复合材料相比,通过将 GO-MOF 纳米杂化物添加到 EP 中,峰值热释放率 (p-HRR) 降低高达 41%,总烟雾产生量减少高达 30%,证明了提高环氧树脂的阻燃性能。通过查阅文献可知,通过将GO/Ln-MOF纳米粒子引入环氧树脂中,环氧树脂的防腐稳定性得到了很大的提高,达到了500%的水平。粘合强度提高了100%。此外,储能模量比提高百分位约为 20%,断点处的能量提高了 275%。
