Abstract

AbstractSpace charge effects on direct current (DC) conductivity and the thermally stimulated depolarization current (TSDC) in the semicrystalline polyacrylonitrile–methylacrylate [P(AN–MA)] films have been investigated. The conduction was found to be controlled by space charge limited effect. On the other hand, the TSDC studies point to a superposition of dipole orientation and space charge effects. With the aid of the thermal sampling technique, the complex spectrum could be resolved into its elementary processes. Curve fitting has been carried out and peak parameters were determined. Information related to the motion of dipolar groups could be obtained. The compensation effects is observed to be valid and the value of the compensation temperature (Tc = 343 K) greatly differs from the glass transition temperature (Tg = 383 K). From the DC and TSDC studies considerations, the origin of the three conduction regions appearing in the 1n σ vs. 1/T could be explored. © 1994 John Wiley & Sons, Inc.
