▎ 摘 要
NOVELTY - A covalent organic graphene composite material is prepared by adding benzene formaldehyde, para-phenylene diamine and catalyst acetic acid in amino graphene at mass ratio of 0.5-2:1:1, and heating the mixture in a reactor at 120 degrees C for 12-72 hours. USE - Covalent organic graphene composite material for use in electric vehicle and capacitor (Claimed). ADVANTAGE - The material has stable performance, to form electric vehicle use is a new energy storage system of a material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing covalent organic graphene composite material.
