Abstract
The present invention relates to a method for producing a conductive composite material, as well as the composite material capable of being obtained by said method. The conductive material is obtained from a composite polymer matrix, which is formed by aggregation of composite conductive particles consisting of particles of a polymer matrix, having a diamter d50 of between 1 and 4000 μm, coated with a layer of electrically conductive material consisting of at least one metal. The ratio of the thickness of the conductive layer to the diameter d50 of the polymer matrix particles is between 0.0025:100 and 1.5:100, said thickness being less than 300 nm.
