4. Conclusions
A graphite material is exfoliated to form graphene particles, and the effect of nanoparticle volume fraction on the material properties of inhomogeneous fluids with suspended graphene nanoparticles is investigated at different temperatures or under oxidation conditions. The present study aims to provide a fundamental understanding of the thermal and viscosity properties of inhomogeneous fluids with suspended graphene nanoparticles. Particular emphasis is placed upon the effect of nanoparticle volume fraction on the material properties of inhomogeneous fluids with suspended graphene nanoparticles. The major conclusions are summarized as follows:
