Dielectric Characteristics of a Silica–Water Nanocomposite

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The dielectric properties of an amorphous nanoporous silica/water composite are studied. The dielectric constant of SiO2 is shown to rise from 10 (for a pretreated sample) to 105 upon raising humidity to ~80%. The results demonstrate the possibility of obtaining a superparaelectric state of water molecules in silica nanopores.
