Figure 2

Examples of simulation supercells showing nanocarbon–HDPE composites with nanocarbon fillers consisting of (a) C60 fullerenes, (b) C61 graphene flakes, (c) C540 fullerenes, and (d) C541 graphene flakes. The polymer chains are represented by sequences of linked green segments. Magnified views in the vicinity of (e) two C1087 graphene flakes showing densification and layering of polymer chains near the matrix–filler interface and (f) a C540 fullerene showing similar densification, albeit significantly reduced compared to that of (e).
