SILVER NANOPARTICLE COMPOSITION COMPRISING SOLVENTS WITH SPECIFIC HANSEN SOLUBILITY PARAMETERS

摘要

A metal nanoparticle composition includes an organic-stabilized metal nanoparticle and a solvent in which the solvent selected has the following Hansen solubility parameters: a dispersion parameter of about 16 MPa0.5 or more, and a sum of a polarity parameter and a hydrogen bonding parameter of about 8.0 MPa0.5 or less. The metal nanoparticle composition is suitable for printing conductive lines that are uniform, smooth and narrow on various substrate surfaces. The metal nanoparticle composition is able to form printed conductive features having a coffee ring effect ratio of about 1.2 to about 0.8, a surface roughness of about 15 or less and a line width of about 200 microns or less.
