Thermal inkjet printing of polyaniline on paper

Thermal inkjet printing of copper tetrasulfonated phthalocyanine (CuTsPc) as a semiconducting layer on flexible MIS capacitors

“…Such applications become even more interesting when solution-processed organic materials are used to produce low-cost and flexible devices, which can be achieved by printing techniques, for instance [19][20][21] . However, to succeed in the printing of organic devices with suitable electrical characteristics, the development of strategies to improve material properties is extremely important 20,22 . Previously, we demonstrated an ink formulation to print aqueousinsoluble polyaniline (PANI) using a commercial thermal desktop printer 22 .…”

“…In the literature other strategies reporting ink formulation of different materials for thermal inkjet (TIJ) printing can also be found [23][24][25][26] . TIJ printing is an attractive method that exhibits advantages such as accurate droplet positioning, minimal waste production, reasonable printing speeds and compatibility with different flexible substrates and materials 21,22 . Additionally, the use of commercial desktop printers is very versatile for rapid device prototyping and patterning at real low-cost production [20][21][22] .…”

“…TIJ printing is an attractive method that exhibits advantages such as accurate droplet positioning, minimal waste production, reasonable printing speeds and compatibility with different flexible substrates and materials 21,22 . Additionally, the use of commercial desktop printers is very versatile for rapid device prototyping and patterning at real low-cost production [20][21][22] . The TIJ technique, however, requires the use of water-based materials (inks) with very specific properties such as appropriate viscosity (ca.…”

“…33 mN m -1 ) and boiling point (ca. 90-95 °C) 21,22 . Thus, the fine tuning of material properties is mandatory to fulfill these particular characteristics, which can be achieved through the formulation and modification of standard materials.…”
