Ultra-fine bubbles tune drying ink droplets without chemical additives

Дата публикации: 13-07-2026 13:20:01

Researchers from Tokyo Metropolitan University studying inkjet printing have introduced ultra-fine bubbles into ink droplets and showed that their drying behavior can be tuned without additives. They discovered that the shape of the particle-laden film left after a droplet dries can be radically modified by adjusting the number of bubbles. This could benefit the printing of microdevices, where ink additives can come out of solution and negatively affect the properties of ink deposits. The study will be published in the October 2026 issue of Precision Engineering.
