A novel inkjet printing procedure based on a well-dispersed aqueous Ag ink and a molecular adhesive layer is presented for the fabrication of highly conductive and narrow patterns exhibiting the excellent adhesion property on a glass substrate. The aqueous dispersion of silver nanoparticles is synthesized via a chemical reduction method in the aqueous medium in which an anionic polyelectrolyte is incorporated as both a capping agent and a dispersant. Owing to the electrosteric repulsion characteristic of the anionic polyelectrolyte, the prepared aqueous Ag ink exhibits the long-term dispersion stability. A molecular adhesive layer is deposited on a glass substrate using either aminopropyltriethoxysilane or mercaptopropyltriethoxysilane. The distinctive functional group of the molecular adhesive layer plays a critical role in the adhesion property as well as high contact angle appropriate for forming the narrow Ag patterns, which is achieved only with the aqueous ink. It is demonstrated that the resulting ...
