▎ 摘　　要

As a category of long-term protective coating, phenol formaldehyde (PF) has been extensively applied in the nuclear industry. However, PF might emerge adverse degradation processes under the gamma ray irradiation environment, which greatly restricts its further applications as the highly-efficient protective coatings. For the sake of addressing this issue, herein, a novel phenol noncovalent modified graphene oxide/phenol formaldehyde nanocomposite (GPF) has been constructed via in situ guiding phenol formaldehyde micromolecules format on the well-dispersed graphene oxide surface. Electron spin resonance and electrochemical tests intensively demonstrate that the highly dispersed graphene could act as an enhanced radical scavenger and retain the corrosion resistance properties for the GPF composites under the gamma irradiation environment.
