Thermally Conductive Graphene-Polymer Composites: Size, Percolation, and Synergy Effects
TL;DR: In this paper, the authors report a facile and scalable dispersion of commercially available graphene nanoplatelets (GnPs) in a polymer matrix, which formed composite with an ultrahigh thermal conductivity of 12.4 W/m K (vs 0.2 W/k for neat polymer).

Enhanced mechanical properties of nanocomposites at low graphene content.
TL;DR: Graphene platelets significantly out-perform carbon nanotube additives in terms of mechanical properties enhancement, and may be related to their high specific surface area, enhanced nanofiller-matrix adhesion/interlocking arising from their wrinkled (rough) surface, as well as the two-dimensional geometry of graphene platelets.

Carbon nanotube-reinforced epoxy-composites: enhanced stiffness and fracture toughness at low nanotube content
TL;DR: In this article, double-wall carbon nanotubes (DWCNTs) and an epoxy matrix were produced by a standard calandering technique and a very good dispersion of both DWCNT and carbon black (CB) was observed.
