Nanocomposites based on polymer-clay mixtures are a growing area of interest due to their potential in flexible applications. In this study, new nanocomposite materials were produced from the components of recycled thermoplastic as the matrix and montmorillonite as the filler by using a co-rotating twin screw extruder. During this study, recycled Poly(Ethylene Terephthalate), rPET, was mixed with organically modified quaternary alkyl ammonium montmorillonite in the contents of 1, 2, and 5 weight %. Three types of clays were evaluated during the studies. For comparison, 2 weight%clay containing samples were prepared with three different clay types, Cloisite 15A, 25A, 30B.Even though, 2wt% Cloisite25A shows better mechanical properties, 2 wt% Cloisite30B is better in respect of electrical properties.
