▎ 摘 要
NOVELTY - Preparation of graphene or graphene/aluminum composite material comprises ultrasonically dispersing graphite oxide in organic solvent, adding red aluminum reducing agent in organic solvent, dispersing at 25-120 degrees C for 5 minutes-48 hours, filtering, washing solid substance with aromatic hydrocarbon or ether substance, deionized water and hydrochloric acid, and drying. USE - Method for preparing graphene or graphene/aluminum composite material (claimed) used as aluminum hydroxide precursor. ADVANTAGE - The method prevents agglomeration.
