TL;DR: The process yields a wrinkled sheet structure resulting from reaction sites involved in oxidation and reduction processes, and functionalized graphene produced by this method is electrically conducting.

TL;DR: In this article, a detailed analysis of the thermal expansion mechanism of graphite oxide to produce functionalized graphene sheets is provided, where it is shown that the decomposition rate of the epoxy and hydroxyl sites exceeds the diffusion rate of evolved gases, yielding pressures that exceed the van der Waals forces holding the graphene sheets together.

TL;DR: An unzipping mechanism to explain the formation of cracks on GO and cutting of carbon nanotubes in an oxidizing acid is proposed and two small GO platelets are employed to show that through the binding of a new epoxy group or the hopping of a nearby existing Epoxy group, the unzipped process can be continued during the oxidative process of graphite.

TL;DR: In this paper, the role of vacancy defects in the fracture of carbon nanotubes under axial tension was investigated using density functional theory and semi-empirical methods, and molecular mechanics (MM) calculations with a Tersoff-Brenner potential.
