Smart Multifunctional Nano-inks: Fundamentals and Emerging Applications covers nano-inks and how they can be used in inkjet printers for printing complex circuitry on flexible substrates or as a paste for 3D printers. Microstructures can be 3D-printed using nano-inks in a combination of high-resolution plasma printing and subsequent rotogravure printing. In addition, smart multifunctional nano-inks are not only required for the electronic, but also in other applications, such as for secure inks, for currency, and in immigration documents. This book focuses on fundamental design concepts, promising applications, and future challenges of nano-inks in various areas, such as optoelectronics, energy, security and biomedical fields. The current challenge for the successful industrial application of nano-inks is in the preparation of a stable dispersion of advanced materials for nano-inks. The functionalization, synthesizing, and theoretical modeling provide the solution for most of the current issues, but there are still remaining challenges which are covered in this comprehensive resource.
