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. This analysis has been made for different organic solvents as absorbates (acetone, 2-propanol, 1,2-dichlorobenzene, acetonitrile and chloroform) in order to study how their different physical and chemical properties affect the efficiency of the absorption process. Furthermore, the possibility to obtain even complex structures through DLP-3D printing of formulations containing different amount of PILs has been evaluated. The efficiency of this process and the properties of the obtained solid materials have been investigated.
