Negative dielectric permittivity of poly(acrylic acid) pressed pellets
Source abstract
Abstract
Abstract Spontaneously formed temperature-frequency zone of negative dielectric permittivity e′ 65 °C is thought to be the reason of this phenomenon. The frequency width of the zone steadily increases with temperature up to T = 83 °C, and then sharply increases at low-frequency side. This effect might be related to the anomalies in temperature dependencies of thermodepolarization currents in water at 83 °C. Spontaneous manifestation of e′
