Functional inks

The first five chapters of the book focus on fundamental aspects of printing technologies, pigments and ink formulations and, and interactions of the inks with the substrates. The next six chapters focus on actual inkjet inks formulations and raw materials, by discussing the main groups of inks waterborne, solvent-based, and UV inks. The last five chapters present rmique ink systems and functional inks, such as those for obtaining 3D structures or printed electronic devices.

The colored liquids in Fig. 4.17 are examples of different semiconducting polymers in solution. These colored solutions can be thought of as functional inks and applied to substrates using the methods of modern printing technology. Inkjet printing appears to be an ideal way to deposit the red, green and blue pixels of a full-color display. Fig. 4.18 illustrates this remarkable opportunity. 

The 3D printing technique allows functional inks to be precisely patterned in filamentary form (10).
