N2 - Well-exfoliated polymer-graphite nanocomposites made using only untreated, as-received graphite and polymer were prepared by solid-state shear pulverization (SSSP). X-ray diffraction of 2.5 wt% graphite-polypropylene (PP) nanocomposites made via SSSP revealed an almost total suppression of the scattering peak characteristic of the inter-graphene sheet spacing (0.335 nm) within graphite; electron microscopy revealed the presence of nanoplatelets in the nanocomposite with thicknesses of several to thirty layered graphene sheets. Relative to neat PP, 2.5 wt% graphite-PP nanocomposites exhibited a 100% increase in room-temperature Young's modulus and a 60% increase in yield strength. Such property enhancement has not been previously observed in polymer-graphite nanocomposites/hybrids of the same or lower graphite content (treated or untreated) and produced without solvent/sonication or in nanocomposites made by co-processing PP and organoclay leading to confirmed exfoliation.
