Isotactic Polyproyplene-Exfoliated Graphene Nanoplatelet (iPP-xGnP~(TM)) nanocomposites were prepared through an in-situ polymerization technique. Single site metallocene catalysts polymerized propylene within a dispersion of xGnP nanoparticles. The nanocomposites showed increased crystallization and melting temperatures, along with increased elastic moduli. The 1.3 wt% composite showed an increase in ductility over the neat polymer.
