Method for obtaining composite conductive materials based on conductive polymers, with controlled dielectrical properties

摘要

Disclosed is a method to obtain a film of composite material based on particles of conductive polymer, stabilized by a highly steric or highly ionic surfactant. The efficient stabilization of the particles makes it possible to control the progress of the dielectrical properties of the materials as a function of the conductive entity content, leading to the preparation of films with variable impedance. The method can be applied to the making of coatings that meet goals related to electromagnetic wide- band attenuation. FIG. 2 .
