摘要：
In view of the disadvantages of epoxy resin composite materials such as poor thermal oxygen aging performance and white surface, carbon nanotubes, graphene and molybdenum dioxide were used as modified filler to study the effects of three fillers and their composite epoxy resin composite on thermal oxygen aging performance. The results of resistance test show that the addition of fillers could delay the rising trend of resistance of epoxy resins in the process of thermal oxygen aging to some extent, among which the effect of graphene is the most obvious. At the same time, the macroscopic aging performance of the samples and the SEM microscopic images show that the introduction of graphene and other lamellar nano-fillers has a positive effect on aging retardation, and can significantly improve the surface whitening of epoxy resin composites during aging process. © 2021, Editorial Board of Polymer Materials Science & Engineering.
