Abstract

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.
