▎ 摘　　要

NOVELTY - Preparing graphene nanocomposite material by synchronized reduction of graphite oxide comprises pulsed laser ablation of a rotating metal target to obtain high activity high reactivity metastable nanomaterial colloid, mixing with graphite oxide, and placing in a dark place. USE - The method is useful for preparing graphene nanocomposite material by synchronized reduction of graphene oxide (claimed). ADVANTAGE - The nanocomposite material has high strength. The method is simple, and environmentally friendly.
