Abstract
A palladium precursor composition contains a palladium salt and an organoamine. The composition permits the use of solution processing methods to form palladium layers.
Claims17
A palladium precursor composition, comprising a palladium salt, an organoamine, and a water immiscible organic solvent;
- wherein the palladium salt is a palladium carboxylate;
- wherein the organoamine is octylamine, nonylamine, or decylamine;
- wherein the palladium salt is from about 5 wt % to about 30 wt % of the precursor composition;
- and
- wherein at least a portion of the palladium salt and the organoamine form an amorphous palladium organoamine complex.
2 more elements
A process for forming a palladium layer on a substrate, comprising:
- receiving a palladium precursor composition that comprises a palladium salt, an organoamine, and a water immiscible organic solvent;
- solution coating the substrate with the palladium precursor composition;
- and
- heating the palladium precursor composition to form the palladium layer;
- wherein the palladium salt is a palladium carboxylate;
- and
- wherein the organoamine is octylamine, nonylamine, or decylamine, and
- wherein the palladium salt is from about 5 wt % to about 30 wt % of the precursor composition;
- and
- wherein at least a portion of the palladium salt and the organoamine form an amorphous palladium organoamine complex.
7 more elements
A process for forming an electrically conductive palladium layer on an object, comprising:
- receiving a palladium precursor solution that comprises at least one palladium salt, at least one organoamine, and at least one water immiscible organic solvent, wherein at least a portion of the palladium salt and the organoamine form an amorphous palladium organoamine complex;
- solution coating the object with the palladium precursor solution to form an amorphous coating on the object;
- and
- heating the amorphous coating to form the electrically conductive palladium layer;
- wherein the palladium salt is palladium acetate;
- wherein the organoamine is octylamine or decylamine;
- and wherein the palladium salt is from about 5 wt % to about 30 wt % of the precursor composition.
