| description | In this work, samples of mixed nanoscale iron oxide stabilized with amylopectin were obtained by chemical precipitation in an aqueous medium. This compound has a wide range of applications in biomedical technologies, energy storage and conversion devices due to its supermagnetic properties. The microstructure was studied by scanning electron microscopy and the phase composition by diffractometric method, as well as by computer quantum chemical modeling of the interaction of amylopectin and mixed nanoscale iron oxide. During the study of the phase composition, it was found that the sample is a mixed iron oxide Fe3O4 with a cubic face-centered lattice and a spatial group Fd3m. Based on the analysis of the microstructure, it was found that the sample is formed from particles with a diameter of 24 to 54 nm.As a result of computer quantum chemical modeling, it was found that the interaction of iron oxide nanoparticles with amylopectin is energetically advantageous and chemically stable. The most likely interaction is through a hydroxyl group attached to the C2 first A-bound glucopyranose residue, since optimal values of total energy (E = -3839.330 kcal/mol) and chemical hardness (η = 0.159 eV) are observed during this interaction. |
