Nevertheless, the focused ion beam (FIB) technique for preparing metal and ceramic samples provides another method for preparing polymer nanocomposite samples. It was found that as the OMMT content increases, tensile modulus and tensile strength are increased but impact strength is reduced. Recently, several studies have been conducted to investigate the behavior of polymer based composites reinforced with clay particles, which can remarkably improve the properties of the polymers. During mixing, polymer chains diffuse from the bulk polymer into the van der Waals galleries between the silicate layers.
