Vy. Tretinnik, THE ROLE OF CATIONIC SURFACTANTS IN THE FORMATION OF THIXOTROPIC DISPERSE STRUCTURES OF MONTMORILLONITE, Colloid journal of the Russian Academy of Sciences, 59(1), 1997, pp. 1-6
Results of complex physicochemical, crystallochemical, and rheological
studies of aqueous montmorillonite dispersions are summarized. The ro
le of modifier (bis-quaternary and tertiary-quarternary ammonium salts
) nature in the formation and strengthening of thixotropic disperse sy
stems is established. Some assumptions on the mechanism of interaction
of these cationic surfactants with the surface of the dispersed phase
of montmorillonite suspensions are made; the observed effects of thix
otropic strengthening are explained.
