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.

白藜芦醇功能化石墨烯与二苯基硅二醇共改性环氧树脂

本研究以白藜芦醇功能化石墨烯（Res/rGO）复合材料制备二苯基硅二醇（DP）改性双a环氧树脂（E51），并对其性能表征进行了研究。首先，用DP改性双a环氧树脂（EP），提高其力学性能和热稳定性。然后，将Res/rGO引入到改性环氧树脂（DP/E51）中，制备了一系列改性环氧树脂/白藜芦醇功能化石墨烯（Res/rGO-DP/E51）复合材料。通过对复合材料进行拉伸性能测试，分析了不同石墨烯含量对材料力学性能的影响。结果表明，dp改性环氧树脂的抗拉强度有明显提高，特别是加入适量的Res/rGO后，复合材料的抗拉性能得到进一步优化。白藜芦醇作为一种天然抗氧化物质，在石墨烯表面功能化后，显著改善了复合材料的界面键合和分散性，从而提高了复合材料的整体性能。此外，Res/rGO-DP/E51复合材料表现出优异的热稳定性，具有良好的应用前景。
