Abstract
The replacement of classical materials used in industry with other more important, cheaper and environment friendly ones and also the prevention of corrosion is one of the goals in the research area. Electrotechnical industry and engineering needs this special material. The conductive and semiconductive coatings belong to these special materials and occupy a large application domain in modern industry, used to remove the electrostatic charges, and for the shielding effects (i.e. Faraday screen, protective coat for the high voltage cables etc.).In this paper it is studied the stability in time of semiconductive lacquers based on polianiline.
Keywords: polyaniline; conductive polymers; semiconductive lacquers; dispersions
