Stability of multi-walled carbon nanotube + laponite hybrid particles in aqueous suspensions

- Laponite clay disks (L) stabilize carbon nanotubes (NTs) in aqueous suspensions.
- Effect of stirring velocity on NTs + L suspension stability was studied.
- The suspensions stability versus pH and mass ratio L/NTs was investigated.
- Coagulation concentration of different counterions in NTs + L suspensions was determined.
- The mechanisms of stabilization of hybrid suspensions are discussed.
