“…Recently, there are many considerable efforts to synthesize organic-inorganic hybrid particles because they can provide remarkable properties by the appropriate combination and structuring of the organic and inorganic materials 2 , 3 . For example, a wide variety of colloidal inorganic materials has been used for polymer-based hybrid particles, including titanium dioxide 4 , 5 , iron oxide 6 , zinc oxide 7 , clay 8 , sliver 9 , 10 and gold 11 , 12 . Among the many inorganic coating materials, silica particles are one of the most interesting candidates since they are widely used in many fields, such as colloidal and material science and engineering, and they exhibit special properties, such as biocompatibility, low toxicity, and scalable synthetic availability, that are substantially different from those of bulk material.…”

The synthesis of organic-inorganic hybrid particles with highly controlled particle sizes in the micrometer range is a major challenge in many areas of research. Conventional methods are limited for nanometer-scale fabrication because of the difficulty in controlling the size. In this study, we present a microfluidic method for the preparation of organic-inorganic hybrid microparticles with poly (1,10-decanediol dimethacrylate-co-trimethoxysillyl propyl methacrylate) (P (DDMA-co-TPM)) as the core and silica nanoparticles as the shell. In this approach, the droplet-based microfluidic method combined with in situ photopolymerization produces highly monodisperse organic microparticles of P (DDMA-co-TPM) in a simple manner, and the silica nanoparticles gradually grow on the surface of the microparticles prepared via hydrolysis and condensation of tetraethoxysilane (TEOS) in a basic ammonium hydroxide medium without additional surface treatment. This approach leads to a reduction in the number of processes and allows drastically improved size uniformity compared to conventional methods. The morphology, composition, and structure of the hybrid microparticles are analyzed by SEM, TEM, FT-IR, EDS, and XPS, respectively. The results indicate the inorganic shell of the hybrid particles consists of SiO2 nanoparticles of approximately 60 nm. Finally, we experimentally describe the formation mechanism of a silica-coating layer on the organic surface of polymeric core particles.

In this study, by in situ reduction of Pd 21 ions attached on the surface of the sulfonated polystyrene (PS-SO 3 H) spheres, complete and dense palladium (Pd) nanoparticles (NPs) layer were deposited around PS-SO 3 H spheres. The PS@Pd spheres were wrapped by polypyrrole (PPy) shell, which could avoid escaping of Pd NPs. After selectively etching the PS core, the hollow structures with Pd NPs embedded in PPy capsule shell were obtained. The as-prepared Pd@PPy hollow capsules showed excellent catalytic activity toward the reduction of 4-nitroaniline because of the high Pd NPs loading. Furthermore, good reusabilty was demonstrated seven times without any detectible loss in activity.
