Abstract
A process for preparing a palladium nanoparticle ink comprises reacting a reaction mixture comprising a palladium salt, a stabilizer, a reducing agent, and an optional solvent to directly form the palladium nanoparticle ink. During the formation of the palladium nanoparticle ink, the palladium nanoparticles are not isolated from the reaction mixture.
Claims15
A process for preparing a palladium nanoparticle ink, comprising reacting a reaction mixture comprising a palladium salt, a stabilizer, a reducing agent, and a solvent to directly form the palladium nanoparticle ink;
- wherein the molar ratio of the reducing agent to the palladium salt in the reaction mixture is from about 1:1 to about 5:1;
- and
- wherein directly forming the palladium nanoparticle ink occurs without isolation of the palladium nanoparticles from the reaction mixture.
A process for preparing a palladium nanoparticle ink, comprising:
- preparing an initial mixture comprising a palladium salt, a stabilizer, and solvent;
- adding a reducing agent to the initial mixture to form a reaction mixture, and the molar ratio of the reducing agent to the palladium salt in the reaction mixture is from about 1:1 to about 5:1;
- mixing the reaction mixture to reduce at least a portion of the palladium salt to directly obtain the palladium nanoparticle ink without isolation of the palladium nanoparticles from the reaction mixture;
- and
- optionally diluting the ink by adding additional solvent.
