Functionalised graphene nanosheets have been produced in a green, fast and controllable method by scientists in China. The team used aqueous polycation electrolyte branch poly(ethylenimine) as both a stabiliser and a reducing agent to make the graphene nanosheets, which displayed high solubility and long-term stability in aqueous solution.
The nanosheets did not aggregate and they could be dispersed in aqueous solutions, alkaline solutions, salt solutions and organic solvents. The nanosheets can be used as effective and controllable building templates for applications in various fields, they say.
