▎ 摘　　要

NOVELTY - Preparation of carbon nanotube/graphene conductive hybrid material comprises adding carbon nanotube to concentrated nitric acid and concentrated sulfuric acid, heating to 115-120 degrees C for 0.5-3 hours, standing to room temperature, repeatedly washing with distilled water until neutral, and vacuum oven drying at 60-100 degrees C for 2-6 hours; and ultrasonically dispersing in deionized water, mixing with diluted graphene oxide, heating to 95 degrees C, dripping 1 M sodium hydroxide solution until pH reaches 10, adding hydrazine hydrate, reduction reacting, and stirring. USE - Method for preparing carbon nanotube/graphene conductive hybrid material used for preparing conductive or antistatic polymer (claimed). ADVANTAGE - The material has low agglomeration phenomenon and improved dispersibility.
