Dielectric Properties and Electromagnetic Behaviour of Pan/Nmpy Conductive Composites

S. Ursache, R. C. Ciobanu, M. Olariu, and Alina Neamtu

Abstract—Nowadays, because the synthesis of new materials is a very active field of research and industrial development, the different types of materials available for electromagnetic shielding structures is always increasing. Conducting polymers exhibit excellent electrical, electrochemical and optical properties; however the common usage of these materials has been restricted due to their poor processability and stability. Polyacrylonitrile (PAN) is an outstanding engineering material used in many applications owing to its good mechanical and thermal properties and its low cost [1].
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. 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.

Index Terms—Conductive polymers, dielectric spectroscopy, electromagnetic interference, shielding effectiveness.
