Size-controlled synthesis of graphene oxide sheets on a large scale using chemical exfoliation
TLDR
In this article, the synthesis of graphene oxide (GO) sheets with controlled size on a large scale was developed using chemical exfoliation by simply controlling the oxidation and exfolation procedure, and the mean size of the GO sheets, which has a Gaussian distribution, decreases from 59,000 to 550 nm 2.About:
