Description We have elaborated methods for synthesis of macromolecular metal complexes via homo- and copolymerization
of metal-containing monomers (unsaturated metal carboxylates, metal nitrates acrylamide
complexes. Thermal transformations of such compounds possess the unique way for preparation of nanocomposite
materials when metal (or their oxides and carbides) nanoparticles and a stabilizing polymer matrix
are formed simultaneously in situ. Molecular and supramolecular organization of nanocomposites obtained
can be controlled during the thermal transformation of such monomers in inert or self-generated
atmosphere. The process includes three macrostages: dehydration, solid-phase polymerization, and pyrolysis
of the polymer products formed. The approach makes it possible to adjust the mean particle size in a
given range by just choosing the appropriate reaction conditions. The composition of metal nanoparticles,
their size and distribution on the size as well as the type and thickness of polymer shell can be controlled
on the stage of nanocomposite formation. The nanocomposites obtained reveal ferromagnetic behaviour at
room temperature with high coercive force and magnetic anisotropy. With aim to control the composition
and structure (for example, core-shell type) of ferromagnetic nanomaterials obtained as well as their properties,
the reaction conditions such as temperature, ratio of starting compounds, the type of polymer matrix
can be varied.
