▎ 摘　　要

NOVELTY - Preparing melamine covalent organic framework supported graphene material, comprises mixing 14-130 pts. wt. melamine, 20-2100 pts. wt. acid material, 100-150 pts. wt. graphene oxide and water, adding 28-250 pts. wt. dialdehyde material, and reacting at 120-180℃ for 70-75 hours, taking the solid and purifying and drying to obtain a melamine covalent organic framework-loaded graphene material. USE - The melamine covalent organic framework loaded graphene material is useful in supercapacitor electrode material (claimed). ADVANTAGE - The melamine covalent organic framework loading graphene material has high conductivity and good electrochemical energy storage performance. The method uses the melamine as the COF building block, the cost is low, the nitrogen content is high, the porous channel structure is ordered, the specific surface area is high, and the thermal stability is excellent, the hydrothermal method is used for synthesizing, the method is non-toxic and pollution-free, the synthesis method is simple, and it is easy to be produced in batch. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: melamine covalent organic framework-supported graphene material; and preparing supercapacitor electrode.
