Abstract
The invention relates to a method of preparing a conductive composite material, consisting of performing at least one cycle of deposition comprising the following steps:(a) putting an insulating porous substrate (1) in contact with a solution of a conductive polymer such as polyaniline in a volatile organic solvent such as trifluoroacetic acid, and(b) eliminating the organic solvent by evaporation, for forming a deposit of conductive polymer (5) in the pores (3) of the porous substrate.
