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 ofless than about 500 nm, and a distinct boundary between the copper core and the barriermetal shell. Methods of forming a copper ink are further provided and include an initialstep of synthesizing an amount of copper nanoparticles in an aqueous solution. Anamount of a barrier metal is then added to the copper nanoparticles to form a dispersionof the barrier metal and the copper nanoparticles, and a reducing agent is subsequentlyadded to the dispersion to produce a copper ink comprising core-shell nanostructureshaving a copper core and a barrier metal shell. Copper films are then formed by applyingthat copper ink to a substrate and sintering the copper ink.
