The Role of Solvent Polarity in Graphene Dispersion Dynamics
The dispersion of graphene sheets within a solvent is a significant step in its processing and implementations. The polarity of the solvent plays a critical role in this phenomenon, affecting the aggregation of graphene. Polar solvents, with their ability to form potent dipole-dipole forces, tend to disperse graphene more effectively. 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 analyzing the properties of graphene-based composites in various applications.
