Description	Thermal behaviour of Fe-based (Fe/Fe2O3 core) – polyoxocarbosilane (shell) nanocomposites, prepared by laser-induced co-decomposition of iron pentacarbonyl and hexamethyldisiloxane in the gas phase, was examined by using TGA technique. The thermal decomposition of the polymer shell of the nanocomposite is revealed as a two-stage (low- and high-temperature) evolution of methane. The importance of the low-temperature stage increases and that of the high-temperature stage decreases with increasing amount of the Fe/Fe2O3 cores. The results represent the first thermal data related to nanocomposite metal/polymer system and are explained in terms of heterogeneous catalysis of the polyoxocarbosilane decomposition by the Fe/Fe2O3 core.

Tepelný rozklad polymerního obalu nanokompositu je dvoustupňovou (nízko- a vysoko teplotní) extrusí methanu. Význam nízkotepelného stadia stoupá a význam vysokoteplotního stadia klesá se zvyšujícím se obsahem Fe/Fe2O3 jádra. Výsledky jsou prvým příkladem TGA dat o nanokompositním systému kov/polymer a jsou vysvětleny pomocí heterogenní katalýzy polyoxokarbosilanového obalu Fe/Fe2O3 jádrem. (cs)
