Developing Functional Inks for Direct-Write Systems

The field of Flexible Printed Electronics (FPE) carries great potential in reducing manufacturing costs and increasing versatility. The purpose of this research is to explore various ink chemistries and their suitability for deposition with regards to FPE. Titanium ceramics and silver-titanium-iron nanoparticles were utilized for their potential photocatalytic properties. The resulting inks experienced phase separation or hydrolyzed upon exposure to moisture, suggesting that a surfactant-based synthesis would better improve the inks’ durability.
