Cohesion is the attraction for materials of the same composition. Adhesion for different particles or surfaces. Van der Waals attractive forces operate in both cases. See:

If there is no adsorption-solvent factor for the stability of dispersed systems, then according to the DLFO theory, the total energy of interaction between particles is determined by the competition between electrostatic repulsion and molecular attraction. You have a mixture of very hydrophobic nanotubes and hydrophilic nanoparticles. For hydrophobic tubes, the role of hydrophobic interaction (pushing the tubes out of the water) will be great and they will stick together better.
