WebSilicate Minerals. Talc is a magnesium silicate mineral with a plate-like layered structure in which the octahedral brucite layer is sandwiched between two tetrahedral silica sheets (Castillo, Barbosa, Maiza, & Capiati, 2011). ... Clay when used as a nanofiller enhances the barrier properties of nanocomposite by enhancing the tortuosity of the ... WebThe clay of preference is montmorillonite (MMT) with micro/nanosized particles formed by stacks of three-layer sandwiches: a layer of Mg or Al oxides between the silicate layers. These sandwiches of 0.96 nm thickness and an average diameter of about 100–500 nm are the desired reinforcing entities for polymeric nanohybrids and nanocomposites.
