▎ 摘　　要

In this work, a series of graphene-based composite films were prepared via electron beam (EB) or ultraviolet (UV) irradiation. The influence of the graphene content as well as the irradiation dose on the curing behavior and properties of EB/UV-cured graphene composite films was systematically studied. The curing behavior of the composite films was investigated by the double bond conversion rate as well as the gel content, and the properties of the composite films were studied by TGA analysis and tensile tests. For EB-cured graphene composite films, the curing degree increased with the increase in the irradiation dose (60-360 kGy), and the upper and lower surface was uniformly cured. The curing degree and curing depth of the EB-cured films were not affected by the addition of graphene (0.0-5.0 wt.%). Compared to pure resin film, the EB-cured graphene composite film showed enhanced tensile properties. For UV-cured graphene composite films, the curing degree was also enhanced with the increasing irradiation dose, but it decreased significantly with the increase in graphene content (0.0-5.0 wt.%). The curing degrees of upper and lower surfaces of the UV-cured graphene composite film were not uniform, and the curing depth decreased with the increase in graphene concentration. The addition of graphene had an adverse effect on the thermal and mechanical properties of the UV-cured composite film.
