Graphene/titanium carbide composites were synthesized by means of sol–gel infiltration and spark plasma sintering (SPS). The graphene used in this research was casted into a sponge-like shape, composed of a three-dimensional (3D) network of graphene sheets. The sol–gel infiltration synthesis method allowed the formation of nanostructured ceramics inside the porous structure of graphene networks, thus forming composites. The compositions and microstructures of the Ti–O–C composites changed with the amount of the polymerizable carbon source (i.e. furfuryl alcohol (FA)) in the solution. A high carbon ratio was required to maintain the structure of the graphene network, as the graphene sheets co..View full abstract
