Review on Nanoclays and Its Applications

Nanoclays are  nanoparticles/nanopowder  of layered mineral silicates optimized for use in clay nanocomposites– multi-functional material systems with several property enhancements.  Nanoclays  are a broad class of naturally occurring inorganic minerals. Nanoclays are the most commonly used commercial additive for the preparation of nanocomposites, accounting for nearly 80% of the volume used. And depending on chemical composition and  nanoparticle/nanopowder  morphology, nanoclays are organized into several classes such as montmorillonite, bentonite, kaolinite, hectorite, and halloysite of which plate-like montmorillonite is the most commonly used in materials applications. Montmorillonite nanoclay consists of ~ 1 nm thick aluminosilicate layers surface-substituted with metal cations and stacked in ~ 10 µm-sized multilayer stacks. Even at low nanoclay loading (a few weight %),the entire  nanocomposite  consists of interfacial polymer, with m...
