“…The concentration of aqueous solutions/suspensions is not fixed and should be defined for each system; however, the coating component must always be in excess compared to the core.

We report on the preparation of SiO 2 -based nanoparticles readily available for superhydrophobic applications. In contrast to usual approaches, our process is substrate-free and based on electrostatic adsorption of small SiO 2 particles onto large SiO 2 cores with the aid of poly(diallyldimethylammonium chloride) followed by calcination and chemical modification with trichlorododecylsilane. The as-prepared nanoparticles are in powder form and exhibit stable superhydrophobic behavior at room temperature because of the unique combination between the hierarchical raspberry-like structure and low surface energy. If properly stored, the nanoparticles retain their functional properties for several months.

“…Generally, most of the colloidal composites can be classified into one of the following two groups: core–shell and raspberry‐like particles. [ 1 ] The unique properties of raspberry‐like composites including surface roughness, [ 2 ] surface heterogeneity, [ 3 ] and the presence of specific moieties [ 4 ] results in great number of their potential applications. Raspberry‐like composites are widely applied in catalysis, [ 5–8 ] plasmonics, [ 9–12 ] biology and medicine where they are introduced as platforms for immobilization of biomolecules, [ 13–15 ] in separation processes [ 16,17 ] and as hydrophobic coatings.…”

Among the methods utilized for the preparation of raspberry‐like microcomposites, due to its simplicity and universality, the electrostatically‐driven deposition of nanoparticles at the surface of microparticles is especially attractive. This process, leading to the formation of a single nanoparticle monolayer, is widely reported. On the other hand, no data concerning the electrostatically‐driven formation of nanoparticle bilayers at the surface of microparticles are reported. To fill this gap, the detailed investigation of the formation of silver/hematite nanoparticle bilayers at the surface of polystyrene microparticles is reported. First, the hematite/polystyrene raspberry‐like microcomposites are obtained by immobilization of hematite nanoparticles under an electrostatically‐driven process. The stability of hematite/polystyrene microcomposites at elevated temperatures up to 323 K is monitored using microelectrophoresis. No significant changes in the hematite nanoparticle layer coverage are observed after prolonged time of incubation. This proves the irreversible character of nanoparticle immobilization. Next, the hematite/polystyrene microcomposites are utilized as the interfaces for immobilization of negatively charged silver nanoparticles. This process is quantitatively described using electrokinetic measurements. The changes in the hydrodynamic diameter of microcomposites are also determined. Finally, the validity of the electrokinetic model used in this work for predicting the zeta potential of the silver/hematite/polystyrene microcomposites is confirmed.
