Recent progress on the metal-organic frameworks decorated graphene oxide (MOFs-GO) nano-building application for epoxy coating mechanical-thermal/flame-retardant and anti-corrosion features improvement

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%.
