In Literature, Dielectric constants is found to increase with content of reduced graphene oxide. Is is possible to decrease those value with rGO ? How could we explain it?
Do you have any experimental evidence for reduced dielectric permittivity with increasing reduced reduced graphene oxide content? If yes, what are the volume or weight fractions of the filler and what is the % reduction in permittivity, at which frequency? One would expect increasing permittivity due to interfacial polarization.
Yes, about 1 pinch ( not weight exactly, very small amount) of rGO added reduce dielectric constant about 2 than without rGO at 1 kHz.
What was the dielectric constant of the non-filled polymer and what was it after addition? Is it reproducible? What is the frequency dependence in both cases? Did you check the density of the sample? No bubbles?
