Abstract
The feasibility of inkjet printing of colloidal dispersion inks to arrange colloids in desired locations was investigated with different ink formulations and inkjet process variables. In order to maintain the structural stability of colloidal patterns fabricated on the substrate from externally applied forces such as mechanical, chemical and thermal stimuli, thermally curable binder was formulated into the colloidal ink formulations. Circularly aggregated colloidal pattern uniformly covered with the binder coating was created using a piezoelectric inkjet on a polymer substrate, indicating that colloidal micro-patterning by inkjet printing could be an effective method to control geometry of colloidal patterning on substrates.
