▎ 摘 要
NOVELTY - A graphite is treated with strong acid, and mixed with halogen-substituted aromatic compound and stirred, to obtain graphene oxide. The obtained graphene oxide is thermally treated at 100-450 degrees C. USE - Manufacture of reduced graphene oxide used for manufacturing reduced graphene-polymer composite (all claimed). ADVANTAGE - The method provides reduced graphene oxide having excellent electroconductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of reduced graphene oxide-polymer composite, which involves covalently bonding halogen-substituted aromatic compound to graphene oxide, and thermally treating; and (2) reduced graphene oxide-polymer composite.
