  • Patent number: 11873413
    Abstract: A printable molecular ink that is can be treated (e.g. dried or curable) and sintered using broad spectrum ultraviolet light is provided to produce electrically conductive traces on a low temperature substrate, for example PET. The ink includes a silver or copper carboxylate, an organic amine compound, and may include a thermal protecting agent.
    Type: Grant
    Filed: August 2, 2019
    Date of Patent: January 16, 2024

  • Patent number: 11873409
    Abstract: 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.

  • Patent number: 11746246
    Abstract: A molecular ink contains: a silver carboxylate; 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 organic amine. Such an ink may have higher silver loading, lower viscosity and lower processing temperatures than existing silver inks.

  • Patent number: 11525066
    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 and 0.1-10 wt % of a polymeric binder, or 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate and 0.25-10 wt % of a polymeric binder, and balance of at least one organic solvent, wherein the binder has ethyl cellulose, and the ethyl cellulose has an average weight molecular weight in a range of 60,000-95,000 g/mol and a bimodal molecular weight distribution.

  • Patent number: 11472980
    Abstract: 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.

  • 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.
