Abstract:
The aim of the present work was to investigate the high temperature reaction between Si- C-O fibres and Cl2, and to correlate the carbon layer growth kinetics with their initial composition and structure. Large disparities have been observed between the various materials reaction rates. If a large amount of mixed silicon atom environments increases the reactivity of Si-O-C materials with Cl2, this sole feature does not explain all the experimental results. Traces of heteroelements (Ti, Zr, Al…) or percolated free carbon both appear to bear on the reaction rate. For a better understanding of th

Abstract:
Comparative studies of the structure and thermal behavior of cellulose and composite precursors with additives of silyl-substituted acetylene and alkoxysilanes were carried out. It is shown that the introduction of silicon-containing additives into the cellulose matrix influenced the thermal behavior of the composite fibers and the carbon yield after carbonization. Comparison of the activation energies of the thermal decomposition reaction renders it possible to determine the type of additive and its concentration, which reduces the energy necessary for pyrolysis. It is shown that the C/O rati

Abstract:
Polymer-derived ceramics are a new class of materials synthesized by thermal decomposition of polymeric precursors. The resultant materials are amorphous alloys of silicon, carbon, and nitrogen, which can be converted to crystalline materials by annealing at higher temperatures. This novel chemical-to-ceramic route offers a unique opportunity to tailor the structures and compositions, therefore the properties, of the resultant materials by designing the chemistry of the precursors. In this paper we report the studies on synthesis and oxidation behavior of polymer-derived SiAlCN materials. The

The clay silicate nanolayers possess stable Si-O bonds and high particle aspect ratios comparable to conventional fibers. Their interlayer surface is easily modified by ion-exchange reaction, and the gallery can be intercalated by organic polymer precursors for the formation of organic-inorganic nanocomposites.
