Problems solved by technology

However, in the actual preparation process, since this method is a new graphene preparation method, and the expansion reaction of graphite intercalation compounds is a static reaction process (accumulating reaction heat, accelerating the reaction), there is no relevant method in the prior art. expansion reaction device, so there is an urgent need for a device dedicated to the expansion reaction of graphite intercalation compounds
