In this work the effect of 2.5% and 5% (wt) of organoclay on the mechanical properties and morphology of PLA/EMA-GMA blend was investigated. The nanocomposites were prepared by extrusion followed by injection molding and characterized by X-ray diffraction (XRD), mechanical properties and Scanning Electron Microscopy (SEM). The results showed that better impact strength was achieved when 2.5% (wt) of clay was added to the PLA/EMA–GMA blend. XRD results indicated that this nanocomposite presented a partially exfoliated structure.
