Weband achieved a high dielectric permittivity of over 200 at 1kHz near the percolation threshold (1.01vol%) [11]. The use of graphene or graphene oxide (GO) as fillers in polymer has been studied as well [12–15]. GO is known to have high resistance. Though the GO film itself has a high dielectric constant in the order of 105, it is not ... WebMar 12, 2024 · Electrical properties of epoxy resins reinforced with graphene’s nanosheets or its derivative GO is investigated thoroughly. The broadband dielectric spectroscopy is employed to investigate the complex dielectrics function ε ∗ (ω, T ) = ε' (ω, T) ‒ ε'' (ω, T ), where ε' is the permittivity and ε'' is the dielectric loss.
