ABSTRACT:
Polymer-clay nanocomposites and methods of making the same are provided. In an embodiment, a polymer-clay nanocomposite comprises a non-metal salt of an ionomer and a nanostructured layered clay. An example of the ionomer is a tetra-octyl ammonium salt of sulfonated polystyrene, and an example of the clay is sodium-montmorillonite.
