  • Publication number: 20210095153
    Abstract: A copper-based ink contains copper hydroxide and diethanolamine. The ink may be coated on a substrate and decomposed on the substrate to form a conductive copper coating on the substrate. The ink is low cost and micron-thick traces of the ink 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 compared to traces produced from other copper inks. Sintered copper traces having sheet resistivity of about 20 m?/?/mil or less may be obtained for 5-20 mil wide screen-printed lines with excellent resolution.

  • Patent number: 10954406
    Abstract: A copper precursor composition contains: a first copper complex of an imine or a first cyclic amine coordinated to a first copper precursor compound; and, a second copper complex of a primary amine or a second cyclic amine coordinated to a second copper precursor compound. A copper precursor composition contains a copper complex of an imine coordinated to a copper precursor compound. The copper precursor composition is thermally degradable at a temperature lower than a comparable composition containing only primary amine copper complexes under otherwise the same conditions to produce a metallic copper film having a resistivity of about 200 ??-cm or less. Inks containing the copper precursor composition and a solvent may be deposited on a substrate and sintered to produce a metallic copper film. The substrate with the film thereon is useful in electronic devices.

  • Patent number: 10883011
    Abstract: A flake-less molecular ink suitable for printing (e.g. screen printing) conductive traces on a substrate has 30-60 wt % of a C8-C12 silver carboxylate or 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.1-10 wt % of a polymeric binder (e.g. ethyl cellulose) and balance of at least one organic solvent. Conductive traces formed with the molecular ink are thinner, have lower resistivity, have greater adhesion to a substrate than metal flake inks, have better print resolution and are up to 8 times less rough than metal flake inks.

  • Publication number: 20200407565
    Abstract: A composite includes a plastic substrate and an electrical insulator layer formed on the plastic substrate. The electrical insulator layer contains boron nitride nanotubes (BNNTs), which may be unmodified or modified BNNTS. The composite is suitable for use in making printed electronic devices. A process includes providing a plastic substrate and forming on at least a portion of a surface of the plastic substrate a layer that contains the BNNTs. A metallic ink trace is formed on a portion of the layer, such that the metallic ink trace is spaced-apart from the substrate. Using photonic or thermal sintering techniques, the metallic ink trace is then sintered.

  • Patent number: 10844238
    Abstract: An ink contains an admixture of a copper nanoparticle, a copper precursor molecule (e.g. a copper-aminediol complex), and a polymeric binder, the polymeric binder containing a polyester, polyimide, polyether imide or any mixture thereof having surface 5 functional groups that render the polymeric binder compatible with and/or soluble in a diol. The ink may be deposited on a substrate providing a trace that is conductive and directly solderable and has better mechanical strength than copper inks containing other types of polymeric binders.

  • Publication number: 20200010707
    Abstract: 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.

  • Patent number: 7566681
    Abstract: The synthesis of Pt and PtRu and other Pt based nano-particles that catalyze the electrochemical oxidation of methanol, carbon monoxide and hydrogen, as well as oxygen reduction, is described. The Pt based catalysts are synthesized in solution forming particles of 0.8 to 10 nm size (forming a “colloidal” solution) and are subsequently applied to a desired substrate as e.g., carbon black, graphite, metals. The application of the nano-sized catalyst particles on the substrates involves electroless deposition at open-circuit, such as immersing the substrate into the colloidal solution or spraying the catalyst particles on the substrate. The Pt, PtRu and other Pt based catalyst can also be directly deposited on the substrate involving the simultaneous reduction and deposition of the Pt based catalysts onto the substrate surface and into its porous structure.
