▎ 摘　　要

NOVELTY - Single-layer graphene is prepared by reducing single-layer graphene oxide by phenol-amine compounds. USE - Single-layer graphene useful e.g. for battery material, energy storage material, electronic device, and electrically and thermally conductive polymer composite material. ADVANTAGE - The preparation of single-layer graphene uses phenol-amine compound, which is green and environment-friendly reducing agent; avoids the toxicity of hydrazine reducing agent; and is suitable for large-scale production. The single-layer graphene can be stably dispersed in water or organic solvent without adding any stabilizer.
