In this research, mercapto-anchoring graphene oxide (GO) and epoxy-anchoring SiO2 nanoparticles (NPs) were assembled by mercapto-epoxy click chemistry to form three-dimensional (3D) point-plane structure nanomaterials (GO-SiO2), and epoxy resin (EP) composites were prepared using the auxiliary thermal blending method. The relationships among surface interfacial interaction, dispersion, and mechanical properties of composites were systematically investigated. The Research finding shows that SiO2 NPs covalently bonding with GO increases interface compatibility and dispersion, which explains epoxy composite strengthening. Compared to epoxy resin, 0.1 wt% GO-SiO2/EP composite has 38.65%, 36.15%, 44.64%, and 61.61% higher tensile strength, flexural strength, flexural modulus, and impact strengths. The enhancement mechanism of GO-SiO2 toward EP was analyzed.

GO-SiO2三维点面纳米材料的制备及环氧树脂力学性能的增强
在这项研究中，通过巯基-环氧点击化学组装了巯基锚定的氧化石墨烯（GO）和环氧锚定的SiO 2纳米颗粒（NP），形成三维（3D）点平面结构纳米材料（GO-SiO 2），采用辅助热共混法制备了环氧树脂（EP）复合材料。系统地研究了复合材料表面界面相互作用、色散和力学性能之间的关系。研究结果表明，SiO 2 NPs 与 GO 共价键合提高了界面相容性和分散性，这解释了环氧复合材料的增强。与环氧树脂相比，0.1 wt% GO-SiO 2 /EP复合材料的拉伸强度、弯曲强度、弯曲模量和冲击强度分别提高了38.65%、36.15%、44.64%和61.61%。分析了GO-SiO 2对EP的增强机理。
