Abstract: Disclosed is a dispersion adjuvant for metal nanoparticles, which comprises an amide derivative. Metal nanoink comprising the dispersion adjuvant is also disclosed. The dispersion adjuvant helps metal nanoparticles to be dispersed in a solvent in the presence of a dispersant, inhibits metal particles from agglomerating among themselves, and increases the content of metal nanoparticles in a solvent. Additionally, interconnection lines formed by using the nanoink have an increased content of metal per unit area, and thus provide improved conductivity.
