Double glass transition in polyethylene naphthalate structural relaxation by MDSC, BDS and TSDC
J. C. Cañadas, J. A. Diego, S. Diez-Berart +4
In this work, we present an experimental study of the primary and secondary relaxations of the semi-crystalline polymer polyethylene naphthalate (PEN), by Modulated Differential Sc…
Comparison of pulsed electroacoustic and thermally stimulated depolarization current measurements of thermally poled PET electrets
S. E. Parsa, J. C. Cañadas, J. A. Diego +2
We have compared measurements of a set of polyethylene terephthalate (PET) electret samples by means of pulsed electroacoustic method (PEA) and thermally stimulated depolarization…
Effects of UV radiation on the charge trapping capability of PET
J. C. Cañadas, J. A. Diego, M. Mudarra +2
Poly(ethylene terephthalate) (PET), as most dielectric materials, is able to retain space charge in traps. This allows the material to attain an almost-permanent polarization when…
Sublinear dispersive conductivity in polyetherimides by the electric modulus formalism
M. Mudarra, J. Sellares, J. C. Canadas +1
It can be seen by Dynamic Electrical Analysis that the electrical properties of polyetherimide at temperatures above the glass transition are strongly influenced by space charge. W…
Dielectric study of the glass transition of PET/PEN blends
J. Sellares, J. A. Diego, J. C. Canadas +5
An analysis of the glass transition of four materials with similar chemical structures is performed: PET, PEN and two PET/PEN blends (90/10 and 70/30 w/w). During the melt processi…
Identification of dipolar relaxations in dielectric spectra of mid--voltage cross--linked polyethylene cables
J. Orrit, J. C. Canadas, J. Sellares +1
Medium-voltage cross-linked polyethylene (MV-XLPE) cables have an important role in the electrical power distribution system. For this reason, the study of XLPE insulation is cruci…
