▎ 摘　　要

NOVELTY - Preparation of organic-organic composite carbonaceous nanoplate involves (a) dissolving glucose and 6-12C aromatic compound containing at least one hydroxyl group, and at least one hydrogen can be optionally substituted with an amino group, a carboxyl group, or 1-6C alkyl, and (b) heating the aqueous solution to 150-300 degrees C. USE - Preparation of organic-organic composite carbonaceous nanoplate (claimed) used for graphene oxide such as combination of graphite used as pencil lead. ADVANTAGE - The method is economical, and enables preparation of organic-organic composite carbonaceous nanoplate with high yield and excellent dispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the organic-organic composite carbonaceous nanoplate.
