Yes, there can be several advantages to using a mixture of two solvents rather than a single solvent for exfoliation of 2D nanomaterials:
Enhanced solubility: The use of a mixture of solvents with different polarities can increase the solubility of the 2D nanomaterials. This can help to increase the yield of the exfoliation process and produce a more homogeneous dispersion of the nanomaterials.
Better control of the exfoliation process: The use of a mixture of solvents can provide better control over the exfoliation process. By varying the solvent ratios and properties, it is possible to optimize the exfoliation conditions and achieve a more efficient and controlled process.
Improved stability: The use of a mixture of solvents can also help to improve the stability of the exfoliated 2D nanomaterials. The combination of solvents can provide a more stable environment for the nanomaterials, preventing re-aggregation and maintaining the exfoliated state for longer periods.
Compatibility with other materials: Finally, the use of a mixture of solvents can also make the exfoliation process compatible with other materials, such as polymers or composites. By selecting solvents that are compatible with the target materials, it is possible to produce hybrid materials with improved properties and functionality.
