Shear rheology of graphene oxide dispersions

Graphene oxide (G-O) is a chemically oxidized sheet of graphene. Owing to their functional groups, G-O sheets have found numerous applications in biomedical, electrical and material engineering. The flow properties of G-O dispersions, that is, the rheology, are intimately related to the material processing and design of G-O based composites. In this review, we report recent findings on the shear rheology of both aqueous G-O dispersions and composite materials containing G-O sheets. We focus on aqueous G-O dispersions to understand interactions between G-O sheets. Applications related to materials science and technology are also presented.
