Composition-dependent mechanism of formation of γ-Fe2O3/carboxymethylcellulose nanocomposites

The distribution of nanoparticles in the volume of the composite is determined by a ratio between reagents at the stage of synthesis. At low molar fractions of iron in the system, nanoparticles are formed inside the coils of macromolecules, and nanoparticles expand their formation closer to the surface with an increase in the iron fraction. The size of the nanoparticles remains independent of the polymer/iron ratio in the reaction mixture.
