摘要:
A solution of metal ink is mixed and then printed or dispensed onto the substrate using the dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from the light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that it has low resistivity.
摘要:
A metallic ink including a vehicle, a multiplicity of copper nanoparticles, and an alcohol. The conductive metallic ink may be deposited on a substrate by methods including inkjet printing and draw-down printing. The ink may be pre-cured and cured to form a conductor on the substrate.
摘要:
Forming a conductive film comprising depositing a non-conductive film on a surface of a substrate, wherein the film contains a plurality of copper nanoparticles and exposing at least a portion of the film to light to make the exposed portion conductive. Exposing of the film to light photosinters or fuses the copper nanoparticles.
摘要:
A conductive ink includes metallic nanoparticles, a polymeric dispersant, and a solvent. The polymeric dispersant may be ionic, non-ionic, or any combination of ionic and non-ionic polymeric dispersants. The solvent may include water, an organic solvent, or any combination thereof. The conductive ink may include a stabilizing agent, an adhesion promoter, a surface tension modifier, a defoaming agent, a leveling additive, a rheology modifier, a wetting agent, an ionic strength modifier, or any combination thereof.
