Аннотация:Comparative studies of the structure and thermal behavior of cellulose and compositeprecursors with additives of silyl-substituted acetylene and alkoxysilanes were carried out. It isshown that the introduction of silicon-containing additives into the cellulose matrix influenced thethermal behavior of the composite fibers and the carbon yield after carbonization. Comparison of theactivation energies of the thermal decomposition reaction renders it possible to determine the type ofadditive and its concentration, which reduces the energy necessary for pyrolysis. It is shown that theC/O ratio in the additive and the presence of the Si–C bond affected the activation energy and thetemperature of the beginning and the end of the pyrolysis reaction.
