- Abstract
- The effect of the bias electric field E= (0–10 kV/cm) on the dielectric properties of the VDF60/Tr40 copolymer was studied within the temperature range of 20–110°C. It was found that the dielectric nonlinearity De, is negative in the polar phase and becomes positive above the Curie temperature (TC). The increase in TC under the field E= is not uniform. At E= < Ec (Ec is the threshold field), the Curie temperature is practically independent of E=. At E= > Ec, the increase of TC is observed. The presence of the threshold field indicates the presence of sources of random electric fields in the material under study. It is assumed that they are responsible for the smearing of the ferroelectric phase transition.
