Nanocomposites with well-defined organic polymers are hybrid materials with large interphase between two incompatible organic and inorganic segments. The well-defined organic segments are generated by controlled/living polymerization. Due to its simplicity, robustness and tolerance to impurities, radical polymerization is preferred. Atom transfer radical polymerization has been most often used, since it is perhaps most versatile. Inorganic component can comprise colloidal spherical particles, flat layered structures or macroscopically flat wafers but also irregular inorganic surfaces. The nancomposites are formed by covalent linkage between the incompatible organic and inorganic parts. Both grafting from surfaces and onto surfaces was employed for that purpose. Spherical polymer brushes were synthesized by the ATRP of styrene,n-butyl acrylate and methyl methacrylate from initiators covalently attached to the surface of colloidal silica and silsesquioxanes. In a similar way core-shell colloids were prepared by block copolymerization using ATRP. Polymer brushes were formed by grafting from and onto flat silicon surfaces and functionalized carbon black.

Key words: nanocomposites, organic/inorganic hybrids, controlled radical polymerization, atom transfer radical polymerization, ATRP
