▎ 摘 要
NOVELTY - The preparation of functionalized graphene, involves adding graphite powder and amino group-containing silane coupling agent to grinding device, sealing the grinding device, purging grinding device with carbon dioxide gas, starting grinding device, milling, washing with ethanol or acetone, filtering and drying. USE - Preparation of functionalized graphene. ADVANTAGE - The method enables preparation of functionalized graphene ensuring increased dispersibility in organic solvent and lubricating oil, by simple, safe, environmentally-friendly and economical process.
