Furthermore, the role of thermal energy and concentration of graphene in the dispersion system cannot be overlooked.
The Role of Solvent Polarity in Graphene Dispersion
Graphene's exceptional properties arise from its remarkable arrangement. However, its inherent tendency to clump presents a significant barrier to widespread utilization. Solvent polarity plays a essential role in mitigating this difficulty by influencing the distribution of graphene sheets in solution. Polar solvents, with their tendency to communicate strongly with polar species, can effectively solubilize graphene by forming strong associations. Conversely, non-polar solvents tend to exhibit weak forces with graphene, leading to poor dispersion.

Graphene's remarkable properties have sparked immense enthusiasm across diverse scientific disciplines. However, achieving uniform dispersion of graphene nanomaterials within various matrices remains a significant obstacle. This hindrance stems from graphene's inherent tendency to aggregate due to its strong surface forces. To overcome these difficulties, researchers are constantly exploring novel dispersion strategies.
Recent advances in this field have focused on designing of novel approaches that effectively disrupt graphene interactions and promote uniform distribution. These innovations include the use of ultrasonication, chemical modifications, and the incorporation of surfactants. The adoption of these dispersion technologies holds tremendous potential for realizing graphene's full capabilities in a broad spectrum of applications.
