Controlled Thermolysis of Macromolecule-Metal Complexes as a Way for Synthesis of Nanocomposites

摘要

Metal-polymer nanocomposites, which comprise nanoparticles of metals and/or their oxides and carbides uniformly distributed in stabilizing polymer matrices, are obtained through solid-phase polymerization of metal-containing monomers followed by controlled thermolysis of synthesized metal-containing polymers. The composition, structure and properties of nanocomposites obtained were studied using the methods of X-ray diffraction, electron microscopy, IR spectroscopy and DSC-TGA thermal analysis. The main stages and kinetics peculiarities of thermal transformations of metal-containing monomers were estimated. It is shown that nanoparticles present in these systems have a characteristic core-shell structure that comprises a metal-containing core and a surface layer, i.e., a polymer shell.
