A Hybrid Material Based on Poly-3-Amine-7-Methylamine-2-Methylphenazine and Magnetite Nanoparticles

Resumo

For the first time, under the conditions of in situ oxidative polymerization, a hybrid dispersed magnetic material based on poly-3-amine-7-methylamine-2-methylphenazine (PAMMPh) is obtained in which nanoparticles Fe₃O₄ are dispersed in an electroactive polymer matrix. According to the results of TEM and SEM, Fe₃O₄ nanoparticles have sizes of 4 nm < d < 11 nm. Using IR spectroscopy it is established that the chain propagation proceeds via the addition of C–N between 3-amine groups and the para position of phenyl rings relative to nitrogen. The chemical structure, phase composition, and the magnetic and thermal properties of the nanomaterials versus the synthesis conditions are investigated. It is shown that the Fe₃O₄/PAMMPh nanocomposite material is superparamagnetic and thermally stable.
