Development of Advanced Materials Based on Polymeric Ionic Liquids Formulated for Additive Manufacturing

3D printing is a revolutionary set of technologies with many benefits. It allows to manufacture objects much more quickly, precisely, sustainably and economically than using traditional processes. However, one of the biggest drawbacks of this technology is the limited availability of printable materials. The studies carried out in this thesis have focused on developing and optimising new materials based on polymeric ionic liquids, specially designed for 3D printing. In addition, these polymeric materials have demonstrated to be able to effectively stabilise and encapsulate a variety of molecular compounds with advanced properties, such as perovskites, metal nanoparticles or conductive polymers. The functionalities of these molecules were successfully transferred to the 3D printed objects. Thus, it has been possible to print functional devices with the desired properties. The PIL-based formulations were evaluated in several applications, including antibacterial and photodegradation of pollutants.
