The Role of Solvent Polarity in Graphene Dispersion Dynamics
The distribution of graphene sheets within a solvent is a significant step in its processing and implementations. The nature of the solvent plays a critical role in this process, modifying the stability of graphene. Polar solvents, with their ability to form potent dipole-dipole forces, tend to disperse graphene more successfully. Conversely, nonpolar solvents with weaker intermolecular forces often lead to clumping of graphene nanomaterials. This correlation between solvent polarity and graphene dispersion dynamics is essential for analyzing the behavior of graphene-based composites in various applications.
