Having considered how VOCs affect the human health and enhance threatening environmental issues, it is clear that their removal from the atmosphere is necessary. Various existing methods to achieve this have been considered: the aim of this work is to verify if the absorption of VOCs may be provided by polymer-based filters, with a porous structure, realized by DLP- 3D printing. In particular, the considered polymeric material must be characterized by a certain amount of poly (ionic liquid)s, which have been studied a lot recently for their versatility and their ability to capture volatile pollution agents, such as CO2. In this case, the goal is to know how the presence of PILs influence the absorption capacity of the polymeric matrix, and, in general, to investigate their efficiency as VOCs’ absorbants.
