▎ 摘 要
NOVELTY - Quick preparation of graphene macroscopic body by self-propagating combustion sequentially comprises preparing 0.5-20 mg/ml graphene oxide water or alcohol solution, adding into container, freeze drying at - 60 to - 10 degrees C to obtain graphene oxide macroscopic body, taking out the graphene oxide macroscopic body from the container, igniting a portion of the macroscopic body for spontaneous combustion at room temperature, and after the combustion is finished, obtaining graphene macroscopic body. USE - The method is for quick preparation of graphene macroscopic body used e.g. for supercapacitor, lithium battery, and sewage disposal. ADVANTAGE - The method has short operation time, quick preparation speed, simple device, easy operation, mild condition, low cost, and easy amplification technique, and provides graphene macroscopic body with high quality and good performance.
