Title: Synthesis of mesoscale, crumpled, reduced graphene oxide roses by water-in-oil emulsion approach

Abstract

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 GO sheets, with corrugated surfaces and particle sizes tunable in the range of ~800 nm to 15 μm. Excellent reproducibility for particle size distribution is shown for each selected speed of homogenizer rotor among different sample batches. The morphology and chemical structure of these produced GO roses was investigated using electron microscopy and spectroscopy techniques. In conclusion, the proposed synthesis route provides control over particle size, morphology and chemical properties of the synthesized GO roses.
