The Role of Solvent Polarity in Graphene Dispersion Dynamics
The distribution of graphene sheets within a medium is a significant step in its processing and applications. The polarity of the solvent plays a pivotal role in this process, affecting the aggregation of graphene. Polar solvents, with their ability to form significant dipole-dipole interactions, tend to disperse graphene more effectively. Conversely, nonpolar solvents with weaker intermolecular forces often lead to clustering of graphene nanomaterials. This correlation between solvent polarity and graphene dispersion dynamics is essential for analyzing the behavior of graphene-based materials in various applications.
