<p>Mesoscale crumpled graphene oxide
roses (GO roses) were synthesized by using colloidal graphene oxide (GO)
variants as precursors for a hybrid emulsification/rapid evaporation approach.
This process produced rose-like, spherical, reduced mesostructures of colloidal
graphene oxide, with corrugated surfaces and particle sizes ranging from ~800 nm
to 15 μm. The morphology and chemical structure of these produced GO roses was
investigated using electron microscopy and spectroscopy techniques. The
proposed synthesis route provides control over particle size, morphology and
chemical properties of the synthesized GO roses.</p>
