Special Issue Information

Dear Colleagues,

Photopolymerization technology is now undoubtedly rooted in our day-to-day lives. Being widely recognized as environment-friendly, energy-saving and relatively low-cost, photopolymerization processes are constantly under the magnifying glass due to both their broad applications in the coating, adhesive, ink, lithography and dentistry industries and their huge potential in additive manufacturing and other emerging fields.

However, the ongoing research on novel photopolymerizable systems is pushing the boundaries of this technology further and further, hinting at new possibilities and advanced applications.

The scope of this Special Issue, “Latest Progresses in Photopolymerization”, is to present original research articles and review papers on cutting-edge works ranging from the synthesis to processing, characterization and applications of novel photopolymerizable systems.

The present work aimed to prepare novel bio-based composites by adding fillers coming from agro-wastes to an acrylate epoxidized soybean oil (AESO) resin, using liquid crystal display (LCD) 3D printing. Different photocurable formulations were prepared by varying the reactive diluents, iso-bornyl methacrylate (IBOMA) and tetrahydrofurfuryl acrylate (THFA). Then, two fillers derived from different industrial wastes, corn (GTF) and wine (WPL-CF) by-products, were added to the AESO-based formulations to develop polymer composites with improved properties. The printability by LCD of the photocurable formulations was widely studied. Bio-based objects with different geometries were realized, showing printing accuracy, layer adhesion, and accurate details. The thermo-mechanical and mechanical properties of the 3D-printed composites were tested by TGA, DMA, and tensile tests. The results revealed that the agro-wastes’ addition led to a remarkable increase in the elastic modulus, tensile strength, and glass transition temperature in the glassy state for the systems containing IBOMA and for flexible structures in the rubbery region for systems containing THFA. AESO-based polymers demonstrated tunable properties, varying from rigid to flexible, in the presence of different diluents and biofillers. This finding paves the way for the use of this kind of composite in applications, such as biomedical for the realization of prostheses. Full article
