Conductive inks for inkjet printing based on composition of nanoparticles and organic silver salt

In this article, conductive inks for inkjet printing with high content of silver nanoparticles with the addition of organic silver salt and polymer additives are developed and investigated. Silver nanoparticles are shown to be stably dispersed in a solvent and the presence of a silver salt and a polymeric surfactant ensures the viscosity necessary for printing. A print of test images is performed using a laboratory inkjet printer equipped with an industrial small-droplet printhead followed by annealing of printed patterns at 150–250°C, and their structural and electrical properties are investigated. Simultaneous presence of polymer additives and silver salt is found to influence the structure of the forming conductive layer and the conducting properties

Thermal Transformations of Bismuth (III) Tartrates

Received: 28.06.22. Revised: 12.08.22. Accepted: 12.08.22. Available online: 25.08.22.The processes of oxidative thermolysis of bismuth tartrates [Bi(NO3)(C4H4O6)]·3H2O and BiC4H3O6·H2O precipitated from bismuth nitrate solutions was studied by the methods of X-ray diffraction, thermal analysis, IR spectroscopy and chemical analysis. The staging of thermal transformation processes was determined. Morphological studies of initial precursors and the final products of their thermal transformations were carried out. The expediency of obtaining finecrystal powders of the tetragonal bismuth oxide modification β-Bi2O3 with uniform sized particles by oxidative thermolysis of BiC4H3O6·H2O was shown.This work was performed in accordance with the thematic plans of Novosibirsk State Technical University (TP-KhKhT-1_22) and Institute of Solid State Chemistry and Mechanochemistry, Siberian Branch of the RAS (121032500064-8)
