摘要： In a method of fabricating graphite flakes applied in a graphite nanomaterial, mesophase pitch and an organic solvent are used to produce a carbon precursor slurry, and the carbon precursor slurry is coated by a scraper to produce the graphite flakes. Since the method of using natural graphite as a raw material in production requires a number of purification processes to manufacture an expanded graphite powder before the graphite flakes can be produced, and thus the fabricating cost is very high, and other high-priced materials such as polyimide (PI) or graphene also will increase the total cost.
