The aim of this project was to evaluate the structure and properties of the commercialized polymer/clay nanocomposites. The project was carried out by participating members of IUPAC’s Polymer Division Subcommittee on Structure and Properties of Commercial Polymers. Two commercialized Nylon/clay samples were received and distributed among the participating laboratories of the subcommittee. The basic structure, such as molecular weight, degree of dispersion of the clay, gallery spacing of the clay, and more were characterized, and the structure was correlated with the properties such as thermal stability, tensile strength, tensile modulus, and elongation at break. The aim was to provide information on these newly developed and commercialized nanocomposite materials to the potential users of these materials. Although the nanocomposite had some exfoliated clay platelets dispersed in the Nylon matrix, it also contained intercalated clay structures. The composition of these intercalated and exfoliated structures had significant effect on enhancing the modulus and strength properties of the nanocomposite. The basic structure and properties were reported in a publication titled “Structure and Properties of Polyamide-6 & 6/66 /Clay Nanocomposites” authored by S. Venkataramani.
