▎ 摘　　要

NOVELTY - Preparation of frozen graphene comprises mixing graphite raw material and solvent at ratio of 1: 1-1: 5, uniformly stirring with non-ionic chelates at ratio of 10: 1-5: 1 to prepare graphite liquid, vacuumizing at - 1 to - 6 Pa, vacuum-cooling for 2 times to - 170 degrees C, treating in hot water at 100 degrees C to obtain graphene, freezing to grow ice crystals, swelling, separating by hot water at 100 degrees C, and heating at 270 degrees C. USE - Method for preparing frozen graphene (claimed).
