Abstract :
Electrical conductivity of polyethylene terephthalate (PET) films was studied as a function of hydrostatic pressure P from 50 to 500 bars at T=100°C over a range of field F up to 2 MV/cm. It is found that the current density increases with F and decreases with P. Analysis of the conductivity variations showed that ionic conduction in PET is predominant by using Miyamoto´s model
