Inkjet printing of carbon nanotubes
Résumé
Photolithography process are classically used to manufacture electronic devices. Printing techniques are presently developed as simple and cheap alternatives. Among the different printing techniques, inkjet printing offers a simple, direct and contactless process, with a resolution at the micron scale. In this lecture, we will present the fundamental and technical issues of the inkjet technique, as well as some basic requirements for the inks. We will then focus on the printing of conductive patterns by inkjet, essentially from metallic nanoparticles or carbon nanomaterials (carbon nanotubes, graphene). We will especially discuss the formulation of the inks, the microstructure of the printed patterns and their electrical properties.
