Epoxy resin has a wide range of applications in aerospace, automotive, coating, packaging, etc. However, the impact resistance of epoxy resin is weak and its toughness is relatively low affected by its structure, which limits its development in advanced fields. To improve the mechanical properties of epoxy, the surface functionalization of graphene oxide (GO) has attracted wide attention as a good additive in the epoxy matrix due to its high mechanical performance. The edge of its lamellar is connected with abundant oxygen-containing functional groups such as the hydroxyl group and carboxyl group, which makes GO have good hydrophilicity and are evenly dispersed in water. At the same time, it can interact with epoxy to form a stable chemical bond, which can play a positive role in improving the comprehensive mechanical properties of the material. This paper aims to summarize the synthetic methods of the graphene-modified resin matrix and explains the mechanism and application of GO/epoxy. Finally, the future development direction and application prospects of graphene-modified resin matrix composites are discussed.
