Abstract

In this study, the preparation of diphenylsilylene diol (DP)-modified double-A epoxy resin (E51) with resveratrol-functionalized graphene (Res/rGO) composites and their performance characterization were investigated. Firstly, the double-A epoxy resin (EP) was modified with DP to improve its mechanical properties and thermal stability. Then, Res/rGO was introduced into the modified epoxy resin (DP/E51), and a series of modified epoxy resin/resveratrol functionalized graphene (Res/rGO-DP/E51) composites were prepared. The effects of different graphene contents on the mechanical properties of the materials were analyzed by conducting tensile property tests on the composites. The results showed that the DP-modified epoxy resin exhibited a significant improvement in tensile strength, especially after the introduction of an appropriate amount of Res/rGO, the tensile properties of the composites were further optimized. Resveratrol, as a natural antioxidant substance, significantly improved the interfacial bonding and dispersion of the composites after functionalization on the graphene surface, thus enhancing the overall performance of the composites. In addition, the Res/rGO-DP/E51 composites exhibited excellent thermal stability, which has a good application prospect.
