Abstract: The invention concerns compositions for manufacturing composite materials containing a polyaniline. These compositions are formed by a solution in a solvent such as m-cresol of the following constituents: a) a conductive polyaniline protonated by means of a protonation agent able to promote the dissolution of the polyaniline in the solvent, for example phenylphosphonic acid, b) an insulating polymer chosen for example from amongst the cellulosic polymers and polyvinyl chlorides such as cellulose acetate, and c) an insulating plasticiser such as a mixture of dimethyl phthalate, diethyl phthalate and triphenyl phosphate. By pouring this solution and evaporating the solvent, it is possible to obtain a flexible film of conductive composite material having good electrical and mechanical properties.
