Abstract (en)

Forming a conductive coating on the surface, comprises providing a substrate having a surface applying a dispersion to the surface, where the dispersion comprises at least one liquid dispersant, and electrostatically stabilized silver nanoparticles having a zeta potential of -20 to -55 mV in the dispersant at a pH value of 2-10, and heating one or both of the surface and the dispersion applied on it to a temperature of 50[deg] C below the boiling point of the dispersant to 150[deg] C above the boiling point of the dispersant. Independent claims are also included for: (1) the dispersion comprising the components as above per se and optionally further additives; and (2) preparation of the dispersion, comprising reducing a silver salt to silver with a reducing agent in at least one dispersant in the presence of at least one electrostatic dispersion stabilizer.
