| Popis: | The size, shape, and number density of deposits were investigated in the deposition of graphene on highly oriented pyrolytic graphite substrates by the graphene solution liquid droplet method. Block-shaped aggregates of graphene and sheet-like graphene deposits were observed. The number density of the block-shaped graphene was about 50 times larger than that of the sheet-like graphene due to the aggregation of the graphene films in the pristine graphene solution. Ultrasonication fragmented the block-shaped graphene and increased the number density of sheet-like graphene by about ten times. The remaining block-shaped graphene with heights greater than 25 nm was almost eliminated selectively by centrifugation. |
