The Role of Solvent Polarity in Graphene Dispersion Dynamics
The dispersion of graphene flakes within a solvent is a significant step in its processing and implementations. The polarity of the solvent plays a key role in this phenomenon, affecting the suspension of graphene. Polar solvents, with their ability to form potent dipole-dipole bonds, tend to distribute graphene more successfully. Conversely, nonpolar solvents with weaker intermolecular forces often lead to clumping of graphene nanomaterials. This relationship between solvent polarity and graphene dispersion dynamics is essential for understanding the characteristics of graphene-based structures in various applications.
