Abstract
In this study, we obtained copper nanoparticle (Cu NP) films exhibiting low resistivity and strong adhesion with respect to various substrates by drop-casting the Cu NP ink with polyvinylpyrrolidone (PVP) after being sintered at 250 °C. PVP functioned as a dispersant in the ink and as an adhesive at the interfaces between the Cu NPs and the substrates. Aggregation of the Cu NPs in the ink resulted in the creation of a porous NP film after...
