▎ 摘  要

NOVELTY - The method involves collecting discharged graphene in a new container. The container is heated to the boiling point of the alkane. The alkane is vaporized from the aggregate of the graphene (1). The container is cooled to a temperature lower than the melting point of the organic compound to prepare the organic compound. The collection of individual graphenes covered with a collection (2) of fine crystals of the organic compound in the container is formed. The load is applied to the container to break the graphene aggregates and arranged flat in the container. The graphene aggregates are covered with a collection of fine crystals of the organic compound. Each piece of graphene is taken out, and is covered with a solution in which an organic compound is dissolved in any alkane having 5-8 carbon atoms. Each graphene covered with a group of fine crystals of the organic compound is taken out from the group of graphene separated into the graphene. USE - Method for producing graphene aggregate from collection of graphite particles and extracting each graphene from graphene aggregate to have scaly graphite particles on surface of two parallel plate electrodes. ADVANTAGE - The large amount of graphene is manufactured at low cost. DETAILED DESCRIPTION - The method involves flatly packing a collection of lumpy graphite particles. The parallel plate electrode is immersed in any alkane having 5-8 carbon atoms filled in a container, and the other parallel plate electrode is further placed. The two parallel plate electrodes are superposed on one of the parallel plate electrodes. The two parallel plate electrodes are separated and separated through a collection of the scaly graphite particles or through a collection of the massive graphite particles. The two parallel plate electrodes are immersed in the alkane. The direct current (DC) potential difference having a predetermined size is applied to the gap between the two parallel plate electrodes. The magnitude of the potential difference is large. An electric field corresponding to the value obtained by dividing the value by the size of the gap between the two parallel plate electrodes is applied to the collection of the scaly graphite particles, or is applied to the collection of the massive graphite particles, and the electric field is applied to the collection of the lumpy graphite particles. The interlayer bonds of all the graphite crystals forming the scaly graphite particles or the lumpy graphite particles are simultaneously destroyed upon application. The collection of graphenes composed of the basal plane of the graphite crystals is formed in the gap between the two parallel plate electrodes. The aggregate of graphene is produced, graph from the aggregate of graphite particles. The gap between the two parallel plate electrodes is widened. The two parallel plate electrodes are tilted in the alkane, and the container is left and right, front and back, and so on. The aggregate of graphene deposited in the gap between the two parallel plate electrodes is collected from the gap between the two parallel plate electrodes, by repeatedly applying vibrations in three directions up and down. The two parallel plate electrodes are taken out from the container after moving into the alkane. The homogenizer device is operated in the alkane in the container. The aggregate of graphenes is produced in which the graphenes are overlapped with each other through any alkane having 5-8 carbon atoms, in which the aggregate of compounds is produced in the container, and the second step of producing the aggregate of the graphenes are dissolved in the alkane. The organic compound is mixed with the graphene aggregate in which the graphenes are overlapped with each other via the alkane, and the graphene aggregate is dispersed in the solution in which the organic compound is dissolved in the alkane. The graphene is repeatedly vibrated in three directions of left and right, front and back, and up and down to form a group of graphene on which the graphenes are overlapped with each other via the solution. The graphene is formed on the bottom surface of the container as the shape of the bottom surface.
