In the studies we used bentonites hydrophobically transformed through surface modification with organic polymers. They were compared with commercially available bentonites modified with polymers of the Teq gel HD, Swell gel as well as with the pure Fluka bentonite and local bentonites, originating from Zakłady Metalowo-Górnicze Zębiec. Alterations in physicochemical properties were demonstrated using scanning electron microscopy, dynamic light scattering, elemental analysis and X-ray techniques. Elemental analysis confirmed bentonite processing with polymers in cases of Teq gel and Swell gel samples. Morphological and particle size studies demonstrated a destructive effect of polymer modification on bentonite structure including evidently decreased diameter of particles and agglomerates.
