The Role of Solvent Polarity in Graphene Dispersion Dynamics
The spreading of graphene layers within a solvent is a significant step in its processing and implementations. The nature of the solvent plays a critical role in this event, influencing the aggregation of graphene. Polar solvents, with their ability to form significant dipole-dipole interactions, tend to separate graphene more efficiently. Conversely, nonpolar solvents with weaker intermolecular forces often lead to clustering of graphene nanomaterials. This relationship between solvent polarity and graphene dispersion dynamics is essential for comprehending the properties of graphene-based materials in various applications.
