The Structure and Properties of EPDM/PP/OMMT Nanocomposites by Melt Extrusion

The EPDM/PP/OMMT nanocomposites were prepared with three different types of OMMT by melt extrusion method. The microstructure and mechanical properties of the nanocomposites were investigated. The intercalated structures of the nanocomposites were confirmed by transmission electron microscopy (TEM). The mechanical results showed that the OMMT (FMR242#) has the best reinforcement. When the content of OMMT was lower than 4wt. %, the mechanical properties of the nanocomposites improved greatly with the increase of the OMMT content.
