摘要： A molecular ink contains a silver carboxylate (e.g. silver neodecanoate), a solvent (e.g. terpineol) and a polymeric binder comprising a polyester, polyimide, polyether imide or any mixture thereof having functional groups that render the polymeric binder compatible with the solvent. Such an ink may have good thermal stability with higher silver carboxylate content.

摘要： A process for finishing a conductive metallic layer (e.g. a layer of copper metal) involves coating a molecular silver ink on the conductive metallic layer and decomposing the silver ink to form a solderable coating of silver metal on the conductive metallic layer. The molecular silver ink includes a silver carboxylate, a carrier and a polymeric binder. The process is additive and enables the cost-effective formation of a silver metal finish on conductive metallic layers, which both protects the conductive metallic layer from oxidation and further corrosion and allows soldering with lead and lead-free solders.

摘要： A copper-based ink contains copper acetate, 3-dimethylamino-1,2-propanediol and a silver salt. The ink may be coated on a substrate and decomposed on the substrate to form a conductive copper coating on the substrate. The ink provides micron-thick traces and may be screen printed and thermally sintered in the presence of up to about 500 ppm of oxygen or photo-sintered in air to produce highly conductive copper features. Sintered copper traces produced from the ink have improved air stability, and have improved sheet resistivity for 5-20 mil wide screen-printed lines with excellent resolution.

摘要： A molecular ink contains a silver carboxylate, an organic amine compound, an organic polymer binder, a surface tension modifier, and a solvent. The ink may be used to produce conductive silver traces on a substrate for use in fabricating electronic devices. The ink is particularly useful for producing conductive silver traces on a shapeable (e.g. stretchable) substrate in a low temperature sintering process. Also, a process for producing a conductive silver trace on a shaped substrate involves depositing the molecular ink on a shapeable substrate, drying the ink on the shapeable substrate to form a non-conductive trace containing the silver carboxylate on the shapeable substrate, forming the shapeable substrate into a shape to produce a shaped substrate so that at least a portion of the non-conductive trace is situated on a shaped portion of the shaped substrate, and sintering the shaped substrate to decompose the silver carboxylate to metallic silver thereby producing a conductive silver trace on at least the shaped portion of the shaped substrate. The process reduces potential for cracking of conductive silver traces on shaped substrates.

摘要： A composite material suitable for use in sensing and catalysis applications with conjugated polymers non-covalently bound to the carbon nanotubes. The conjugated polymers have alternating aromatic (Ar) units and bipyridine (BPy) units. Metal nanoparticles having a size that is between about 0.3 nm and about 5 nm are bound to the conjugated polymers at respective BPy units, thereby anchoring the metal nanoparticles to the carbon nanotubes. Thus, a metal salt solution was added into the polymer/carbon nanotube solution to form a metal-BPy complex, which is in situ photo reduced to metal nanoparticles. Therefore, the formed nanoparticles are tightly anchored to the nanotube and can be self-regenerated by room light to offer the material a high performance and durability.
