Abstract:
The main problem in preparing stable and printable inks containing nanoparticles
for inkjetprinting is to overcome the strong agglomeration of the particles in
dispersion medium. In thisstudy, the silver particles with diameter around 50 nm
were produced by a simple wet chemistrymethod. Stable aqueous printable inks
were formulated by using the combination of a triblockcopolymer and high
intensity focused ultrasound (HIFU). Various factors that affect the
inkstability, such as, copolymer content and time of HIFU treatment, were
investigated. The inkcontaining 5 wt% silver has a viscosity of about 2 mPas and
surface tension 30 mN/m at 25◦C,which meet inkjet printer requirements. Such
inks have been successfully printed on Al2O3ceramics and low-temperature co-
fired ceramics (LTCC) and the printed films show lowresistivit
