Formation of mineral nanoparticles inside of the hydrogel matrix was proved by X-ray diffraction analysis, optical spectroscopy, and Energy-dispersive X-ray spectroscopy. It was shown that the nature of polymer matrix has an essential effect on the formation of crystal phase when synthesizing the mineral nanoparticle inside of hydrogels. The rate of the CdS nanoparticle formation depended on the nature of the hydrogel matrix: in anionic matrices it was higher than in cationic ones, while the Cd/S ratio depended on the crosslinking density of the polymer net. In the presence of starch in the hydrogel matrix, the crystal phase of calcium phosphates did not form. The hydrogel nanocomposites obtained are highly elastic materials. A possible application of the hydrogel nanocomposites obtained is discussed.
