Environmentally Friendly Approaches Toward the Production of Processable Graphene by Exfoliation of Graphite Using Ionic Liquid
A facile, low-cost and environmentally friendly method was developed to prepare processable graphene materials by direct exfoliation of expandable graphite flakes under wet ball milling conditions in ionic liquids. The graphene nano-sheets obtained in this method were characterized by AFM, Raman spectroscopy, UV-NIR. Thin-film field-effect transistors made from this graphene sheets exhibit ambipolar effect, an average hole mobility of ∼0.29 cm2 V−1 s−1, electron mobility of ∼0.57 cm2 V−1 s−1 was obtained.
