| Abstract Scope |
In the ever-evolving field of materials science, the discovery and exploration of two-dimensional materials have revolutionized numerous technological domains. The selection of effective solvents for graphene was traditionally based on finding liquids with a surface tension similar to that of graphite, aiming to minimize the energy required for forming new liquid-graphene interfaces. However, recent research studies have highlighted the limitations of this solvent selection method.
To gain a better understanding of the complex and highly transient exfoliation dynamics, we have developed a multiphysics model that allow us to calculate the shock waves produced during bubble implosion in liquids with different viscosities, as well as the resulting cyclic and impulsive stresses acting on the bulk graphite materials. In this study, our focus is on uncovering how these stresses forces can influence the exfoliation process by affecting the interaction between the solvent and the layered material. |
