From scanning electron microscopy (SEM) to see the surface of the graphene oxide have a lot of wrinkles, it is because of the ratio of the surface area of the graphene oxide, as well as pleats graphene oxide can also be of potential adsorption sites.
From the scanning mirror (SEM), graphene oxide surface has a lot of wrinkles, because of graphene oxide than the surface area, and these folds can also be a potential adsorption point of graphene oxide.
According to SEM, there are many wrinkles on the surface of graphene oxide, which is due to the specific surface area of graphene oxide. At the same time, these wrinkles can also become the potential adsorption point of graphene oxide.<br>
