Halloysite nanotubes have been attracted due to the promising applications such as drug delivery, chemical carriers and biomaterials. This study explores the behavior of halloysite nanotubes in polyelectrolyte solutions of polyallylamine and polystyrene sulfonate, in order to understand the fundamental characteristics of halloysite as colloidal dispersions. Polarized/depolarized light scattering probed the rotational and translation diffusion, and the results demonstrated the solution behavior of halloysite supported by polyelectrolytes. Small angle X-ray scattering revealed the interactions between halloysite and polyelectrolytes. We discussed the stabilization of halloysite based on the steric and depletion interactions. The results provide understanding the solution behavior of halloysite and contribute to the development of novel materials using halloysite. |
