Patent number: 11525066Abstract: 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.Type: GrantFiled: November 24, 2020Date of Patent: December 13, 2022Assignees: National Research Council of Canada, Groupe Graham International Inc.Inventors: Arnold J. Kell, Sylvie Lafrenière, Chantal Paquet, Patrick Malenfant, Olga Mozenson

Patent number: 11472980Abstract: 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.Type: GrantFiled: February 8, 2018Date of Patent: October 18, 2022Assignee: National Research Council of CanadaInventors: Arnold J. Kell, Chantal Paquet, Olga Mozenson, Patrick Roland Lucien Malenfant, Bhavana Deore

Patent number: 10883011Abstract: 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. In addition, the shear force required to remove light emitting diodes bonded to the traces using Loctite 3880 is at least 1.3 times stronger than for commercially available flake-based inks.Type: GrantFiled: June 19, 2015Date of Patent: January 5, 2021Assignees: Groupe Graham International Inc., National Research Council of CanadaInventors: Arnold Kell, Sylvie Lafreniere, Chantal Paquet, Patrick Malenfant, Olga Mozenson
