| 摘要 |
<p>The invention relates to a method for preparing an aqueous suspension of carbon nanotubes, that comprises: contacting in an aqueous medium said nanotubes with at least one dispersant comprising a copolymer including at least one anionic hydrophile monomer and at least one monomer containing at least one aromatic group substituted by at least one chain containing one or more oxygen atoms, said chain linking the aromatic group to the unsaturated or cyclic chain of the monomer capable of opening during the formation of the copolymer, the weight ratio between the dispersant and the carbon nanotubes ranging from 0.6:1 to 1.9:1; and mechanically processing the mixture thus obtained using ultrasounds or a rotor-stator system or by passing it in a bead or ball grinder, the invention also relates to the suspension thus obtained and to the uses thereof.</p> |
