HOLLOW GRAPHENE MULTILAYED NANOSPHERES

摘要

PURPOSE: A multilayer graphene hollow nanosphere is provided to express optical luminescence or electromagnetism by introducing impurities by the evaporation or deposition of metal ions. CONSTITUTION: A multilayer graphene hollow nanosphere has the layered structure by graphene layers. The multilayer graphene hollow nanosphere has an outer diameter of 25 nm ~ 300 nm and an inner diameter of 6 nm ~ 250 nm. The interlayer distance of graphene is 0.34 nm ~ 0.60 nm, and the thickness of the multilayer graphene is 3.4 nm ~ 60 nm. The outer surface is hydrophilic by containing a hydroxyl group, and the inner curved surface forming hollow is hydrophobic by containing a metal carbide. The outer surface is converted into hydrophobic by the physicochemical reduction.
