Carbon soot, as might be seen in Figure 1.10, already possesses a structure very much alike that of nano-onions. Only the roof tile arrangement of the graphene platelets in soot differs from the concentric pattern of intercalated fullerenes in the onions. Hence, it is self-suggesting to try preparing carbon onions from diverse soot materials.

The graphene platelets play a role of effective nucleating agents for PBT a-phase crystals and accelerate the overall crystallization of the nanocomposites. ... 

FuUy separated graphene platelets dispersed within matrix binder (polyaniline, carbonaceous material, amorphous or glassy carbon, or combination) solution and treated by activation or carbonization to increase total surface area. Suspension is then frozen and solvent removed by vacuum sublimation leaving a porous nanographene platelet-polymer composite. 

Fig. 8.8 (Left) Electrical conductivity as a function of filler content for EBA with carbon black, graphene platelets, and hybrid systems of mixtures between carbon black and graphene platelets. Adopted from Oxfall et al. (2015). (Right) schematic representation of a CB/CNT hybrid indicating the preferential localisation of the filler particles, the existence of active (conductive) and dead (non-conductive) network branches and the conductive bridges between the two filler networks existing in the matrix...

The problem of the mechanics of reinforcement by a graphene platelet was investigated by Gong et both theoretically and experimentally. They pointed out that since graphene is a crystalline material only a one-atom thick, it poses several fundamental questions in the field of composite mechanics that needed to be addressed ... 

The dispersion of the reinforcement may be poor, particularly at higher volume fractions and this can lead to clustering, a similar problem to that encountered with nanotubes. Also there may be a tendency for the graphene platelets to re-aggregate.
