Abstract:

This paper discusses methods of obtaining ZnS nanoparticles with various concentrations of water molecules on the surface. To do this, they are synthesized in different media: in an aqueous medium, a nonaqueous medium, and with delayed introduction of water. It is found that, in the absence of water, a transparent glassy material composed of self-organized close-packed nanoparticles is formed on the surface of the ZnS nanoparticle (nonaqueous synthesis) after the solvent is removed. The methods of derivatography and IR spectroscopy are used to investigate the surface structure of ZnS nanoparticles stabilized by shells composed of an organic acid. It is shown by IR spectroscopy that chemical bonds are formed between the surface of the nanoparticles and the carboxyl group of the monomer.
