Abstract
Metal-containing (1.5 to 11 wt %) nanoparticles embedded in preceramic polymers were prepared via thermolysis of metal-containing compounds (MCl4 , Cp2MCl2 , MBz4; M = Ti, Zr) in molten oligosilacarbosilane. The materials were characterized by small-angle x-ray scattering, XPS, x-ray RED, and EXAFS. The results show that the nanoparticles (2–20 nm in size) have a complex composition (metallic, chloride, and oxide components) and are linked to the polymer matrix by M–C and/or M–Si bonds.
