How Do Surface Charges Affect Nanoparticle Dispersion?
Surface charges play a pivotal role in the dispersion of nanoparticles in various media. High surface charges lead to strong electrostatic repulsion between nanoparticles, preventing them from clustering together and thus keeping them well-dispersed. Conversely, low surface charges can result in aggregation due to Van der Waals forces overcoming the weak repulsive forces.
