Abstract

The dispersion behavior of graphene oxide and graphene oxide quantum dots in different organic solvents has been investigated. When these dispersed solvents were placed for one year, as-prepared graphene oxide were seen to exhibit long-term stability in three solvents (ethylene glycol, N,N-dimethylformamide and N-methyl-2-pyrrolidone) comparable to that observed for the dispersion of the same material in water. In contrast, as-prepared GOQDs can form dispersions with long-term stability in seven solvents (methanol, ethanol, 1-propanol, ethylene glycol, dimethyl sulfoxide, N, N-dimethylformamide and N-methyl-2-pyrrolidone). Furthermore, the dispersion ability and stability of GOQDs were obviously enhanced in other four solvents (acetone, pyridine, tetrahydrofuran and dichloromethane). The enhancing of dispersion behavior should facilitate the manipulation and processing of graphene-based materials for different applications.
