A gel-form composition characterized by comprising carbon nanotubes and a neutralization-salt type ionic liquid obtained by the neutralization reaction of an acid with a base. This gel-form composition is excellent in carbon nanotube dispersibility and environmental friendliness and can be obtained at a relatively low cost. In particular, using benzoic acid or a derivative thereof as the acid constituting the neutralization-salt type ionic liquid gives a gel-form composition having excellent carbon nanotube dispersibility. L'invention concerne une composition sous forme de gel caractérisée en ce qu'elle comprend des nanotubes de carbone et un sel de neutralisation de type liquide ionique obtenu par la réaction de neutralisation d'un acide avec une base. Cette composition sous forme de gel est excellente en termes de dispersibilité des nanotubes de carbone et de respect de l'environnement et peut être obtenue à un coût relativement faible. En particulier, l'utilisation de l'acide benzoïque ou d'un dérivé de celui-ci en tant qu'acide constituant le sel de neutralisation de type liquide ionique donne une composition sous forme de gel ayant une excellente dispersibilité des nanotubes de carbone.
