The recent introduction of nanoclays as fillers or additives in polymers for various desired effects is a subject of an increased interest for research and development to establish various applications. An increased consumption is indicated by the wider applications of clay nanocomposites
approaching to almost one-quarter (24 pct) in 2005 of the total nanocomposites used.
However, an interesting concern, along with the studies addressing how nanoclays change the behavior of polymeric materials, is to discover what are clays, nanoclays and montmorillonite minerals. The various structures of montmorillonite available in nature and their modification for application are discussed. An attempt is made to review the origin of using clays when
nanotechnology did not exist, coupled with the effects of montmorillonite-based nanoclays on commercially known polymers.
