![]() ![]() The results suggest that van der Waals forces play an important role in the friction-induced exfoliation mechanism, controlling the number of exfoliated layers. The study showed that the critical compressive strainįor exfoliation decreases as the coating thickness decreases, achieving multiple layers of exfoliation. For these simulations, nano-sized graphite was compressed and slid on a SiO 2 coated Cu substrate at different thicknesses of the SiO 2 layer. ![]() Waals forces on graphene exfoliation using molecular dynamics simulations. In our study, we investigated the effect of the van der Obtaining a quantitative understanding of the relationship between frictional force and graphene exfoliation is important for mass production over a larger area. The number of exfoliated graphene sheets presents difficult challenges. In this friction-induced fabrication, however, controlling A simple way to obtain graphene sheets is through the use of frictional forces by rubbing bulk graphite on a surface. For the application of graphene in engineering, cost-effective and mass production methods are essential. ![]()
