摘要 氧化石墨烯(GO)和纳米氧化锌(ZnO)具有优异的性能,但在环氧树脂中容易出现团聚现象,为解决这一问题,必须对其进行表面改性。以七水合硫酸锌为原料,将ZnO负载到GO表面,通过FT-IR,XRD,SEM,EDS,TG和接触角测试,纳米ZnO均匀分散在GO基体上,并可以在不改变GO片层结构的条件下,改善GO的团聚问题的同时降低GO的亲水性。然后将ZnO负载GO与环氧树脂制备纳米ZnO负载GO/环氧复合材料。结果表明:纳米ZnO负载GO/环氧复合材料力学性能和热稳定性明显提高,当ZnO/GO加入量为0.250%(质量分数)时复合材料综合性能最佳,拉伸强度、拉伸模量、断裂伸长率和冲击强度分别比纯环氧树脂提高了99.87%,12.09%,98.35%和151.48%,吸水率比纯环氧树脂降低了81.48%。

Abstract:Graphene oxide and nano-ZnO have excellent performance, but are prone to agglomeration in epoxy. To solve this problem, surface modification needs to be carried out. Using zinc sulfate heptahydrate as the raw material, the zinc oxide was loaded on the surface of graphene oxide. Nano-ZnO was dispersed evenly on GO by FT-IR, XRD, SEM, EDS, TG and contact angle measurement, and the GO-sheet structure can be retained, while the agglomeration is avoided and the hydrophilicity of GO is reduced. Then nano-ZnO/GO/epoxy composite is obtained by nano-ZnO loaded GO with epoxy resin. The results show that mechanical properties and thermal stability of GO/nano-ZnO/epoxy composite are increased significantly. When the mass fraction of ZnO/GO is 0.250%, the overall performance of the composite is the best. The tensile strength, tensile modulus, elongation at break, impact strength of the nano-ZnO/GO/epoxy composites are improved by 99.87%, 12.09%, 98.35%, 151.48% than pure epoxy. Compared with pure epoxy, the water absorption of nano-ZnO/GO/epoxy composite is decreased 81.48%.
