A formalism relating the conductivity of functionalized nanoparticles to constituent ligand molecules and application to water-containing silica.
A formalism is presented that relates adsorption-desorption phenomena to the charge transfer events that take place on the surface of functionalized nanoparticles. The equations are applied to experimental results for the scaled electrical conductivity of a hydrophilic fumed silica with a nanoparticle diameter of 7 nm. Insight into the distribution of water on the surface of the nanoparticles is obtained.
