Patterning and direct writing of nanoparticle inks formulated to provide conductive lines upon annealing. Patterning methods include stamp and tip based methods including microcontact printing and DPN printing. Ink viscosity, metal content, and density can be controlled to provide good results. Low temperature of annealing can be used to generate volume resistivities comparable to bulk resistivity. Long lines can be drawn. Addressable patterning can be achieved.

La présente invention concerne la formation de motifs et l'inscription directe d'encres à nanoparticules formulées pour donner des lignes conductrices après recuit. Les procédés de formation de motifs comprennent des procédés à base de tampon et pointe, notamment l'impression par microcontact et l'impression DPN. La viscosité de l'encre, sa teneur en métaux et sa densité peuvent être contrôlées pour donner de bons résultats. Une basse température de recuit peut être utilisée pour produire des résistivités de volume comparables à la résistivité en masse. De longues lignes peuvent être tracées. Des motifs adressables peuvent être formés.
