| description |
This work has considered the modern ideas on the mechanism of surface modification for used nanodispersed inorganic modifiers with an acidic surface, which significantly affect the hydrate and transport properties of polymeric proton-conducting electrolytes. Authors have proposed an alternative approach consisting of the synthesis of new composite nanoscale systems characterized by high ionic conductivity and developed a method for obtaining composite materials with "core-shell" structure based on an inorganic proton conductor (polyantimonic acid) modified with silicon oxide. The surface morphology of the synthesized nanoparticles has been studied by transmission electron microscopy, and their sizes have been determined. The data on frequency dependence of the electrical impedance are presented and the behavior of the active and reactive components of the impedance and conductivity in the frequency range from 100 Hz to 1 MHz has been analyzed. An equivalent electrical circuit simulating the impedance dispersion for obtained composites with "core-shell" structure based on PAA and SiO2 has been proposed.
