Dielectric properties of mixed composites prepared from nanodisperse silica and triglycine sulfate

The dielectric properties of mixed composites prepared from the nanodisperse silica and ferroelectrics triglycine sulfate have been studied. The performed investigations have demonstrated that, for the composites containing silica in the hydrosol state, the temperature shift of the maximum dielectric permeability is more significant in the case of composites with smaller silica nanoparticles. There is another maximum at lower temperatures in the temperature dependence of the dielectric permeability of the composite containing silica in the gel state, in addition to the maximum detected in the sol-based composite, which is attributed to ordering of the silica particles in the gels in cross-linked structures.
