Core-shell organic-inorganic particles

As mentioned before, hybrid latex particles are usually prepared by seeded emulsion polymerization. In the first stage, well-defined inorganic or organic particles are prepared, while in the second stage a monomer is polymerized in the presence of these well-defined particles. Multistage emulsion polymerization produces structures such as core-shell, inverted core-shell structures, and phase-separated structures such as sandwich structures, hemispheres, raspberry-like and void... 

Coating a given ensemble of nanoparticles with another material yields core-shell nanocrystals (see above see also Refs [272,273]). In these structures, the cores may be any type of colloidal particle, such as metals, insulators, and all classes of semiconductors. Likewise, the shells may consist of type of material, including organics. At this point, attention is focused on semiconductor cores and inorganic shells, mainly of semiconductor materials. 

In recent years, the combination of polymers and inorganic materials to polymer composites comes to steadily growing interest. Synergetic aspects such as chemical resistance or elasticity of the organic compounds and hardness, stability or interesting electrical and optical properties of the inorganic compounds offer an immense potential for new materials or applications. Hofman-Caris presented a detailed review about particle formation procedures as well as chemical coupling procedures that form core shell structures prior to 1994. ... 

A second approach for the generation of structured pre-ceramic polymer-based materials that will be briefly addressed here is based on the self-assembly of organic-inorganic core-shell particles, also referred to as colloidal crystallization. The self-assembly of almost monodisperse colloidal micro- and nanoparticles is a feasible method for gaining access to ceramic functional materials for various applications, especially if the final materials feature an optical band gap [234-238]. In general, colloidal crystals can be prepared from their dispersions by various techniques of deposition or spin coating, which are depicted in Fig. 3 [239, 240].
