Both the dielectric constant-log(time) and the loss tangent-log(time) were regressed in terms of a linear relationship. The dc bias is found to have a strong influence on the dielectric parameters at the start of aging and to suppress the aging of dielectric constant and loss tangent. The frequency dependence of the dielectric aging is also evidently affected by the dc bias. Copyright © Materials Research Society 1998 Wang Y.
