Thin-film particles of graphite oxide were synthesized in high yield by the modified Hummers’ method, in which a very long oxidation period was combined with a high purity purification process. The particles obtained had an average thickness of several nanometers and an average width of about 20 μm. The yield was 122 wt% based on the raw graphite and the recovery of carbon was 68%. Moreover, excellent...
