Abstract

Existing methods of producing high quality graphene/graphite oxides are generally accomplished by exfoliating graphite into flakes and oxidizing the graphite flakes with strong oxidizers under extreme conditions and require careful purification. The oxidizers are typically strong acids used in high concentrations at elevated temperatures requiring complicated purification processes to yield oxidized graphene/sheets. The existing processes can cost up to $12,000/gram. This invention uses a mild oxidant combined with mechanical processing where the sole products are oxidized graphite/graphene and water without the need for further purification.
