Chemistry, Physics and Technology of Surface| Zusammenfassung: | The aim of the paper is investigation of relaxation processes and proton conductivity observed in water structures formed in 1–10 wt. % aqueous suspensions of fumed silica or alumina/silica. The latter contains 1–8 wt. % of alumina. The experiments have been performed using thermally stimulated depolarization current method. It has been shown that oxides promote the formation of 3D network with nanoparticles–water clusters causing the redistribution of sizes of water clusters observed in TSDC spectra. New relaxed structures are formed by nanosilica and these structures are unavailable in the bulk water. |
