Abstract

We report the synthesis of superhydrophobic clay minerals by grafting a monofunctional alkoxysilane -trimethylethoxysilane on different organomodified montmorillonites. The structure of the montmorillonites was changed as evidenced by TGA, FTIR, DLS and X-Ray fluorescence analyses that confirmed the successful functionalisation..
