title = "Enhanced graphene exfoliation and dispersion in injection molded polypropylene nanocomposites processed with supercritical fluid",
abstract = "The effects of melt processing nanocomposites of graphene and polypropylene (PP) with supercritical fluid (SCF) were investigated. Blends of 0.5% graphene (by wt.) were mixed via traditional twin-screw extrusion and with supercritical-fluid gas-laden pellets injection molding-foaming technology (SIFT). Tensile bars were formed using traditional injection molding (IM) and microcellular injection molding (MIM). Samples with graphene had lower melt viscosity and higher thermal stability than their neat PP counter-parts. MIM and SIFT samples with graphene had increased tensile strength. Property enhancements were greater where SCF was used (MIM and SIFT). The ability of SCF to increase exfoliation and dispersion of graphene was determined by X-ray diffraction and Raman spectroscopy. Better exfoliation and dispersion of the nanofillers resulted in the observed property enhancements.",
