Describe the Dispersible Graphene





Graphite is a kind of functional materials for a wide range of excellent performance, but its chemical invalid hinder its development.
 The dispersion of the graphite preparation of graphite is an important tool.
To prepare a functionalized graphite (FG) treatment of graphite oxide (GO) and γ-aminopropyl triethoxy silane, and then reduce the hydrazine hydrate.

No dry stabilization of graphite dispersed in DMF/H2O (9:1, volume ratio) and the acetone/H2O (9:1 volume ratio), and functionalized graphite suspended in DMF/H2O (9:1 volume ratio) can also be dispersed in ethanol or acetone.

Infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) patterns FGO and FG structure.
The results show that the KH-550 amino acids graphite oxide to generate the amide carboxyl reaction occurs in addition to reaction with the oxidation of graphite epoxy.
