The invention concerns an aqueous composition comprising carbon nanotubes and a surfactant, characterized in that the carbon nanotubes are single-wall hydrophobic nanotubes and in that the surfactant is chosen among electropolymerizable surfactant monomers of formula (I):
X-Y-Z (I)
wherein:
X is an electropolymerizable moiety selected from the group consisting of pyrrole, acetylene, phenol, aniline, thiophene, carbazole, indole and azulene
Y is a hydrophobic hydrocarbon chain and
Z is a polar group selected from the group consisting of quaternary ammonium salts, alkylphosphonates and sulfonates.
The invention also relates to a method for the preparation of an aqueous composition as described above, comprising the following steps:
i) solubilisation of the surfactant monomer
ii) addition of the single-wall carbon nanotubes in the aqueous solution comprising said surfactant monomer,
(iii) sonication of the resulting solution, and, optionally
(iv) addition of a protein.
