Figure 6: Results of MD simulation on compression of fullerene arrays as compared with observed compression in type-II GC.

From: Nanoarchitectured materials composed of fullerene-like spheroids and disordered graphene layers with tunable mechanical properties

Figure 6

(a) The volume compression of FLS (solid triangles) as derived from compression of DMLG observed by X-ray diffraction (solid circles) and total volume compression by direct sample volume measurements (open squares). Compression behaviour of graphite (black line)58 is consistent with that of DMLG in type-II GC. Compression curves of MD simulated fullerene aggregates with sphere diameters 4.9, 6.3, 7.7 and 9.1 nm are plotted as solid lines. (b) Snapshots of fullerene aggregates with a sphere diameter of 4.9 nm at selected pressures from the MD simulations. Each inwardly deformed sphere is connected to a neighbouring outwardly protruding sphere, similar to the behaviour observed in mechanical metamaterials9,38, reducing the Poisson’s ratio (v) to zero.
