| Abstract: | The properties of nanodispersions depend sensitively on their microstructure. Precise preparation techniques are needed to ensure controlled and well-defined spatial distribution of particles. We report on the correlation between synthesis, microstructure and dielectric properties. We conclude that temperature-dependent broadband dielectric spectroscopy up to microwave frequencies allows an insight into the microstructure of nanodispersions.
