Seminar: Prof. Marco Sangermano – Sustainable biobased UV-Cured polymers

Biobased monomers are becoming increasingly important to substitute petroleum-based materials [1]. In this seminar I will show different biobased monomers that have been synthesized and exploited both in cationic and radical UV-Curing [2]. Reactivity of curing process was investigated, and the crosslinked materials fully characterized. The same formulations were processed in 3D-printing using the hot-lithography technique when processing epoxy monomers [3]. Curing and printability conditions have been defined and the printed object fully characterized. Finally, UV-Cured composites were achieved by exploiting the frontal induced photopolymerization process [4]. This technique allowed to exploit UV-Curing also to achieve thick composites.
