▎ 摘　　要

Dependences of the dielectric permittivity of a graphene-filled polymer composite and the ESR signal intensity in gamma-irradiated samples of this composite on the concentration of graphene additive have been studied. Anomalous behavior of the permittivity correlates with the ESR signal intensity variation, which is indicative of the possible structural rearrangement in the epoxy resin-graphene filler system.
