Abstract
The metal-containing polymers combine the processability of organic polymers with the physical and chemical characteristics of
the metallic element or complex. Poly(ferrocenylsilanes) with backbone of ferrocene and organo-silane units are currently studied as
charge-transport-dissipation materials and as precursors to advanced nanostructured ceramics. The contribution deals with advantages
offered by plasma assisted chemical vapor deposition can provide for synthesis of copolymers based on ferrocene with hexamethyldisilane.
This method is more suitable for precursors in nanostructured magnetic ceramics as ready for sintering. Synthesis
parameters (flow, pressure, power discharge, temperature, time, monomer dosage and atmosphere) can be adjusted to get final
ceramics precursors with the suitable composition needed in ceramics with tunable properties. Magnetization data showed that ferromagnetic
and paramagnetic phases could be directly tunable as a function of polymer precursor composition and temperature.
