Abstract

Abstract : In this work, the two parts of complex permittivity in the frequency range 1–10 4 Hz were measured for sheet‐shaped samples of silicone rubber under various aging conditions. After that, fitting equations based on Jonscher's law were used to evaluate both the parts. As a result, it is clearly indicated that the fitting parameters in the equation of ϵ r ″ are linearly correlated with those in the equation of ϵ r ″ . This indicates that common information is contained in both ϵ r ′ and ϵ r ″ . A possible mechanism is also proposed to explain this phenomenon. © 2020 Institute of Electrical Engineers of Japan.
