文摘

We demonstrated here the lyotropic liquid crystalline behavior of an aqueous solution of graphene oxide (GO) sheets. Scanning electron microscope experiments revealed GO sheets self-assembled into fiber-like or sheet-like structures at different concentrations under flow conditions. As a result, the solution viscosity decreased dramatically with increasing shear stress.
