▎ 摘  要

NOVELTY - Taking out each graphene from the suspension involves superimposing on one of the parallel plate electrodes in the methanol, where the two parallel plate electrodes are separated from each other through the collection of the flake graphite particles or the collection of the massive graphite particles. The potential difference is applied to the gap between the two parallel plate electrodes, where an electric field corresponding to a value is obtained by dividing the potential difference by the size of the gap between the two parallel plate electrodes. The group of the scaly graphite particles or is applied to the group of the lump graphite particles, the flake graphite particles or the interlayer bonds of all graphite crystals forming the lump graphite particles are simultaneously destroyed. USE - Method for taking out each graphene from the suspension. ADVANTAGE - The method enables to take out each graphene from the suspension that has high viscosity. DETAILED DESCRIPTION - Taking out each graphene from the suspension involves superimposing on one of the parallel plate electrodes in the methanol, where the two parallel plate electrodes are separated from each other through the collection of the flake graphite particles or the collection of the massive graphite particles. The potential difference is applied to the gap between the two parallel plate electrodes, where an electric field corresponding to a value is obtained by dividing the potential difference by the size of the gap between the two parallel plate electrodes. The group of the scaly graphite particles or is applied to the group of the lump graphite particles, the flake graphite particles or the interlayer bonds of all graphite crystals forming the lump graphite particles are simultaneously destroyed. The group of graphene is produced in the gap between the two parallel plate electrodes, after which the gap between the two parallel plate electrodes is enlarged and the two parallel plate electrodes are tilted in the methanol. The vibration in three directions is applied to the container to move the group of graphene into the methanol from the gap between the two parallel plate electrodes. The two parallel plate electrodes are taken out from the container, and the homogenizer device is operated in methanol in the container, and the operation of the homogenizer device impacts the collection of graphene through the methanol. The group of graphene is added. The graphenes are separated one by one in the methanol, and the collection of graphenes separated into the graphenes creates a suspension dispersed in the methanol, after which the melting point is 10 degrees C. The high-viscosity organic compound soluble in methanol is mixed with the suspension in such a proportion that the viscosity of the methanol constituting the suspension is increased by 30-40 times, and the organic compound is dissolved in methanol. The suspension in which the graphenes are separated and dispersed one by one is prepared. The suspension is supplied to a grinder, and the suspension is operated by operating the grinder. The liquids are continuously collided with each other, and the new suspension is separated into each graphene covered with a film of the methanol solution of the organic compound from the collection of graphene consisting of the graphene separated into each one. The each graphene is taken out, the temperature of the graphene cluster is raised to vaporize the methanol, and the graphene cluster is exposed to a temperature lower than the melting point of the organic compound. The collection of graphene becomes a collection of graphene made of graphene covered with a solid film made of the organic compound. The each graphene is taken out from the collection of graphene and suspension in which each graphene is separated in methanol.
