[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] To cite one recent outstanding application, the Panasonic Corporation unveiled in December 2013 a 56 in. 4K (high-pixel density) organic-inorganic hybrid OLED TV, where all the organic materials were deposited using IJP methods.This hybrid TV exhibits properties that are not easily achievable with either organic or inorganic materials alone, such as the best image quality ever, high contrast, fast response rate, high energy efficiency, and with the advantages of being ultrathin and lightweight. [ 16,19 ] Clearly, the manufacture of both organic and inorganic materials using IJP constitutes the next step toward a new generation of advanced materials and modern electronic devices, with a potential multibillion dollar market in the near future. [ 20 ] Therefore, considerable attention has been directed mostly toward the optimization of metal-organic inks, compatible with IJP technology, containing a single metal for direct metallization. [21][22][23][24][25][26][27] Such inks are already commercially available as a consequence of a huge global market desiring cheap inorganic conducting grids.However, the obtaining of sophisticated hybrid inks blending several metal-organic complex raw materials (HMOC) compatible with both the printer and the substrate is still being researched, and this approach is directly linked to the novel capabilities associated with the use of chemical solution deposition (CSD) to prepare self-assembled complex oxide nanostructures and multilayers under mild processing conditions. [28][29][30][31][32][33][34][35][36][37][38][39][40] Achieving the desired composition and the optimum rheological properties, together with the stabilization of several chemical bonds between organic and inorganic molecules, are critical issues during the manufacture of HMOC inks compatible with IPJ technology. In addition, the difference between the ink surface tension (ST) and the surface energy of a hydrophobic substrate has a profound effect on the adhesive strength of the complex linkages between the fl uid and the substrate, causing the ink drop to spread out or stop off during the drying process. [ 41 ] It is, therefore, highly desirable to develop a process Printed electronics is a rapidly growing area of research being explored for the manufacture of large-area and cost-effective electronic devices by the patterned application of functional inks. There are challenges associated with processing the inks compatible with inkjet printing technology and developing effi cient methods to successfully obtain the desired features, particularly when it comes to metal and metal-organic complex inks. Here, a reliable method is developed to achieve a so...
