Tailoring the Surface Properties of Synthetic Clays Via Intercalation, Grafting, or In Situ Incorporation of Organic Moities

Abstract

The present chapter is devoted to recent developments in the area of surface modifications of commercially available synthetic clays by post treatments (i.e. intercalation or grafting) and by one-pot synthesis through a sol-gel process. Special attention is paid to the modifications aimed at forming pillared clays, organoclays, and organic-inorganic hybrids with a 2:1 layered structure. The different approaches are described and debated. The properties of the materials obtained are also discussed.
