The interaction between ionic species and nanomaterials is fundamental to many nanotechnological processes. Ionic species can adsorb onto the surface of nanoparticles, altering their properties such as charge, solubility, and reactivity. These interactions are often governed by electrostatic forces, van der Waals forces, and chemical bonding. For instance, in nanocomposites, the presence of ionic species can enhance the material's mechanical and electrical properties.
