Rezumat
Acesta lucrare investigheaza comportamentul dielectric si electromagnetic ale unor compozite conductive de
poliacrilonitril. Filmele compozite de poliacrilonitril /n-metil-pyrrole au fost preparate prin polimerizarea de pyrrole intr-o
matrice de poliacrilonitril [1]. Concentratii diferite de n-metil-pyrrole au fost adaugate la solutia de
poliacrilonitril/dimetilformamida pentru a realiza polimerizarea pyrrol-ului. Cantitatea de n-metil pyrrole a fost variata,
pentru a investiga influenta concentratiei acesteia asupara proprietatilor dielectrice si electromagnetice si, in special
eficienta de ecranare a materialului

Abstract
This paper investigates the dielectric and electromagnetic behavior of polyacrilonitrile composites thin films.
Polyacrylonitrile/N-Methyl-Pyrrole composite thin films were prepared by polymerization of pyrrole on polyacrylonitrile
matrix [1]. Different concentrations of n-methyl-pyrrole were added to the polyacrylonitrile/dimethylformamide solution to
achieve polymerization of pyrrole. The amount of n-methyl pyrrole was varied in order to investigate the influence of the
concentration on the dielectric and also on electromagnetic properties in special electromagnetic shielding of the
composite polymer.
