- acidic solutions for example sulfuric acid and / or hydrochloric acid solutions
- the carbon nanotubes according to the invention can also be milled before being brought into contact with the monomers or polymers.
- the contacting of the CNTs with the monomers or polymers can be carried out in different ways:
- bringing the CNT powder into contact with the monomer or polymer corresponds, for example, to a dispersion either by direct pouring of the monomer or polymer into the powder (or contrary), either by dropwise introduction of the monomer or polymer into the CNT powder, or by nebulization of monomer or polymer using a spray on the CNT powder.
- the dispersion method can also be carried out by pouring the CNT powder into the solution of the monomer or polymer which may or may not be in the form of a fluid film or of small droplets (dew) deposited on a solid surface.
- bringing the CNT powder into contact with the monomer or polymer corresponds to an adsorption of vapors of the monomer or polymer transported or not by a gas, preferably inert. •
- bringing the NTC powder into contact with the monomer or polymer corresponds to a dry mixture of powder or dry-blend and must be followed a heat treatment in which the passage of the monomer or polymer in liquid or gaseous form takes place in order to ensure the homogeneous and homogeneous mixture of the monomer or polymer with the CNT s.
- the dispersion between the CNTs and the monomer or polymer can also be carried out using a preliminary stage of dissolution of the monomer or in the presence of CNTs in a solvent at a concentration of (CNT and the monomer or polymer) in general less than 30%, preferably less than 20% and preferably less than 15%.

- this preliminary step will be followed by a solvent evaporation phase preferably carried out with stirring so as to recover the composition in powder form.
- a ftration method can be used to accelerate the cycle time to obtain the powder composition of CNT and the monomer or polymer in dry form.
- the bringing into contact of the compounds of different physical form with the CNTs will preferably be made successively; for example, adsorption of monomer and / or polymer in gaseous form on the CNTs and then dry mixing with a second monomer or polymer in solid form or in liquid form.
- This conta / dispersing step may be carried out in conventional synthesis reactors, fluidized Kt reactors or in Z-arm mixer mixers, Brabender, extruder or any other mixing apparatus of the same known type. skilled in the art.
- the mixture between the CNTs and the monomer or polymer remains in the form of a solid powder and retains good flowability properties (it does not take up weight). If necessary, it can be stirred mechanically or not, suspended in a gas in the form of Kt fluidized or not.
- the quantity of monomer or polymer introduced is such that, at the end of this step of contacting and / or dispersing, eKe is below the threshold for which one obtains either a liquid suspension of CNT or a paste in which the NTC are totally or partially pasted.
- This threshold depends in particular on the capacity of the monomer or polymer to impregnate the CNT powder, andin the case where the monomer or polymer is a liquid or a solution, the viscosity of the liquid introduced. In the case where the monomer is acrylic acid, it is in general between 30 and 90%.
- the process for obtaining the composite materials according to the invention comprises a possible thermal treatment of the powder resulting from the step of contacting and / or dispersing.
- This heat treatment consists of heating the powder obtained after the contamination and / or dispersing step so that the physicochemical properties of the powder are modified by heat treatment.
- this heat treatment step may for example consist of heating which allows the polymerization of the monomers and / or a strong physical adsorption and / or chemical adsorption with creation of bonds between the CNTs and a fraction of the monomers or polymer (s) formed.
- the creation of bonds between the NTC and the polymer synthesized in situ via the monomers introduced in the first step or with the polymer added during the first step is characterized in that a part of this polymer created in situ or added to the CNT before the heat treatment is no longer extractable from the CNT by different washings with selective solvents of the polymer, whereas the same washes on the mixture (CNT / monomer or polymer) resulting from the step of placing in contact / dispersion make it possible to extract all the monomer or polymer of the CNTs.
- the heat treatment makes it possible to obtain a strong physical adsorption and / or a chemical adsorption with creation of covalent bonds between the CNTs and the polymer and / or the continuation of the polymerization, with, for example, increasing the molar mass of the polymer.
- the heat treatment may also make it possible to improve the distribution between the liquid and the CNTs.

- the pressure remains substantially equal to atmospheric pressure.
- the product obtained remains in the form of solid powder and retains good flowability properties (it does not take in bulk).
- the product obtained is below that for which one obtains either a liquid suspension of CNT, or a paste in which the CNT grains are totally or partially pasted.
- I ⁇ process for obtaining the compositions according to the invention comprises a possible step of possible separation of the compounds present in the powder composition based on NTC and not bound to the composition resulting from the contacting / dispersing or heat treatment step by physical and / or chemical adsorption.
- This step may for example consist of washing with a solution comprising a solvent of the compounds to be removed and / or drying in order to devolatilize the volatile products.
- a solvent solution it is possible for example to use a solvent solution.
- the washing can be carried out in several steps, preferably between 1 and 5 steps, to improve the separation of unbound compounds. It is also possible to combine several separation techniques, such as washing and drying.
- Drying consists in putting the volatile compounds under conditions of temperature and pressure such that their desorption is facilitated.
- partial evacuation at a temperature lower than the chemical decomposition temperature of the compounds, more in particular less than 200 ° C. and a pressure of between 100 Pa and 20OkPa.
- the purification / separation step may consist of a washing with an aqueous solution of alcohol and more particularly a 50% aqueous solution. 'ethanol

- the weight percentage of composite material in the dispersion is between 0.1 and 10%, advantageously between 0.1 and 5% and preferably between 0.1 and 3%.
- aqueous dispersions according to the invention because of the presence of carbon nanotubes have indeed a high viscosity and have a very good stability over time. In case of prolonged exposure to high temperatures, especially at temperatures above 15O 0 C, they undergo no chemical degradation, and retain a high viscosity. They are also very resistant to shear forces. In addition, they are very insensitive to multivalent metal ions, and are resistant to oxygen and carbon dioxide, and are also stable in the presence of salts.
- the invention is not limited to aqueous dispersions consisting of water and the composite material described above, but also relates to aqueous solutions, including in particular inorganic salts and optionally one or more organic solvents miscible with water.
- the dispersion may also contain other components such as plasticizers, deflocculants, defoamers, anti-corrosion agents, and the like.
