This book describes the topic of nanomaterials used for printed electronics applications. After an introduction to printed electronics, the focus is on various functional nanomaterials for printing, including conducting, semi-conducting, dielectric, polymeric, ceramic and tailored nanomaterials. The preparation and characterization of such materials is discussed along their formulation and preparation as inkjet inks, followed by a selection of applications for printing. The applications include printed interconnects, passive and active modules, as well as specific applications such as solar cells, transparent electrodes, displays, touch screens, sensors and radio frequency identification (RFID) tags. The book concludes with a future outlook of printed nanomaterials.
