摘要：
Copper inks are provided that include a plurality of core-shell nanostructures, with each nanostructure including a copper core and a barrier metal shell, a diameter of less than about 500 nm, and a distinct boundary between the copper core and the barrier metal shell. Methods of forming a copper ink are further provided and include an initial step of synthesizing an amount of copper nanoparticles in an aqueous solution. An amount of a barrier metal is then added to the copper nanoparticles to form a dispersion of the barrier metal and the copper nanoparticles, and a reducing agent is subsequently added to the dispersion to produce a copper ink comprising core-shell nanostructures having a copper core and a barrier metal shell. Copper films are then formed by applying that copper ink to a substrate and sintering the copper ink.
摘要（中）：
提供了包括多个核 - 壳纳米结构的铜油墨，每个纳米结构包括铜芯和阻挡金属壳，直径小于约500nm，以及铜芯和阻挡金属壳之间的明显边界。 还提供形成铜墨的方法，包括在水溶液中合成一定量的铜纳米颗粒的初始步骤。 然后将一定数量的阻挡金属添加到铜纳米颗粒中以形成阻挡金属和铜纳米颗粒的分散体，随后将还原剂加入到分散体中以产生包含具有铜芯的核 - 壳纳米结构的铜油墨 和屏障金属壳。 然后通过将铜油墨施加到基底上并烧结铜油墨来形成铜膜。
