Composite materials offer a combination of properties and adiversityofapplications,whichcannotbeobtainedwith metals, ceramics or polymers alone. In particular, the inser- tion of a conductive phase (metallic or inorganic powders or conductive polymers) in an insulating polymer matrix, can result in an enhancement of its electrical conductivity. Var- iousstudieshavebeenfocusedonsuchelectricallyconduc- tive polymer composition (ECPCs), which do not have the disadvantages of the pure metal (high density, low chemical resistance, complex manufacturing process). The powder loaded polymer becomes a functional material with specific properties, and can be used for electrical or electromagnetic applications,
