چکیده
|
Water-soluble graphene dispersions were fabricated by the exfoliation of graphite functionalized with furfuryl alcohol by diels–alder cycloaddition reaction. the pristine graphite was firstly heat-treated in n-methyl-2-pyrrolidone (nmp) before it was functionalized with furfuryl alcohol, and then, the increased interlayer spacing is propitious for furfuryl alcohol to enter into the lattice and react with graphite. high-resolution transmission electron microscopy and raman spectroscopy indicate that the functional graphene is a high-quality product without any significant defects, and atomic force microscopy shows that the functional graphene consists of single to few layers graphene. moreover, the grafting ratio onto graphene is up to 1.52 mmol/g. therefore, the method provides a feasible route to produce functional graphene.
