This study examines the edge modification of laponite, with a monoalkoxy silane, dimethyloctyl methoxysilane. The influence of ultrasonics, aging time and silane concentration on the resultant materials is examined. The silylated clays are characterized by XRD, IES, TGA, and Si-NMR. The amount of grafted silane was increased by increasing the ratio of silane to clay, sonication of the reaction mixture and ageing the reaction mixture for no more than 24 hours to avoid removal of grafted silane due to equilibrium effects
