Preparation of ZnS Nanopowders and Their Use in the Additive Production of Thick-Film Structures

The preparation of zinc sulfide nanoparticles by chemical deposition was studied. The thermal behavior of the thus-prepared nanopowder in air at temperatures in the range 25-500 degrees C was examined by simultaneous thermal analysis. The product was identified using X-ray powder diffraction and IR spectroscopy. Transmission electron microscopy (TEM) was used to determine the sizes of the product nanoparticles. Functional ink based on the prepared zinc sulfide was used to form thick-film ZnS nanostructures by microextrusion printing. Scanning electron microscopy was used to study the microstructure of the thus-formed coatings, and their electrophysical properties were assessed by impedance spectroscopy. Microextrusion printing was found to be effective not only in bioprinting, but also in the formation of semiconductor coatings.

Automated summary
