Hybrid, Nano-Structurized Materials of Special Purpose on the Basis of Silicon Dioxide

Abstract:

Highly disperse powders of complex morphology, micro- and nanostructure were obtained by treatment of quartz in a planetary-centrifugal mill of a dynamic action in the presence of different organic substances. The surface layer with the thickness of 10-70nm modifying the particle of quartz after mechanochemical treatment is a polymer with encapsulated nanosized particles of iron. Powder material from such highly disperse composition particles of modified quartz is characterized by ferromagnetic and electroconducting properties. A galvanic effect in a nanosize scale is possible to take place on the surface of particles consisting of a polymer nanostucturized film with sites supersaturated with metallic and carbon clusters. The practical realization of such structures is promising when producing highly active sorbents as well as for collecting of oil products spills on the surface of water.
