Abstract (en)
[origin: EP2468826A1] Producing a pickering emulsion for producing conductive coatings, comprises: (a) mixing an aqueous dispersion containing sterically stabilized silver nanoparticles and water with at least one water-immiscible solvent and dispersing into an emulsion, where the content of stabilized silver nanoparticles is 0.5-7 wt.%; (b) separating the emulsion obtained during a residence time in the step (a) into an upper concentrated emulsion phase and a lower aqueous phase by creaming; and (c) isolating the resulting upper concentrated emulsion phase. Producing a pickering emulsion for producing conductive coatings, comprises: (a) mixing an aqueous dispersion containing sterically stabilized silver nanoparticles and water with at least one water-immiscible solvent and dispersing into an emulsion, where the content of stabilized silver nanoparticles is 0.5-7 wt.%; (b) separating the emulsion obtained during a residence time in the step (a) into an upper concentrated emulsion phase and a lower aqueous phase by creaming; and (c) isolating the resulting upper concentrated emulsion phase, where the emulsion phase has a content of silver nanoparticles up to 7 wt.%, preferably up to 4.5 wt.%, based on their total weight. Independent claims are also included for: (1) a pickering emulsion for producing conductive coatings, comprising emulsion stabilized silver nanoparticles, water and at least one organic water-immiscible solvent, where the stabilized silver nanoparticles are present in an amount of 0.5-7 wt.%, based on the total weight of the emulsion; (2) complete- or partial surface coating of surfaces, comprising applying the pickering emulsion completely or partially on the surface, covering the coated surface with a cover such the of water and solvent can escape, drying the covered, coated surface at least at a temperature of less than 40[deg] C, sintering the dried coating in the presence or absence of the cover; and (3) a conductive coating, which is transparent.
