  • Patent number: 10899940
    Abstract: Disclosed herein as a printing method and system which includes providing a substrate and depositing an interlayer composition including a polymer selected from the group of epoxy resins, polyvinyl phenols and poly(melamine-co-formaldehyde) and an interlayer composition solvent on the substrate. The interlayer composition is cured to form cured interlayer. A conductive metal ink composition is deposited on the cured interlayer and the conductive metal ink composition is cured to form a solid metal trace on the cured interlayer.
    Type: Grant

  • Publication number: 20200132559
    Abstract: A temperature sensitive ink composition including a metal oxide nanoparticle; a binder; a solvent; an optional dispersant; and an optional surfactant; wherein the ink composition is a thermistor ink that exhibits a change in resistance which is dependent on temperature. A process for preparing the ink composition. A process including depositing the ink composition onto a substrate to form deposited features; and optionally, heating the deposited features on the substrate to form temperature sensitive features on the substrate, wherein depositing can include ink jet printing or aerosol jet printing.

  • Publication number: 20200031040
    Abstract: Disclosed herein is a printing method and system for forming a three dimensional article. The method includes depositing a UV curable composition and applying UV radiation to cure the UV curable composition to form a 3D structure. The method includes depositing a conductive metal ink composition on a surface of the 3D structure and annealing the conductive metal ink composition at a temperature of less than the glass transition temperature of the UV curable composition to form a conductive trace on the 3D structure. The method includes depositing a second curable composition over the conductive trace; and curing second curable composition to form the 3D printed article having the conductive trace embedded therein.

  • Patent number: 10381583
    Abstract: An electronic device includes a substrate, a gate electrode, a dielectric layer, a source electrode, a drain electrode, and a semiconducting layer formed from an organic semiconductor compound and a photo-responsive polymer. The resistance can be switched to a “low” state by irradiation, and can be switched to a “high” state by applying a gate bias voltage. This can be useful for a memory device.
