Special Issue Information

Dear Colleagues,

Photopolymerization has emerged as a promising method for creating advanced materials and is now widely used across various domains including dentistry, coatings, inks, microelectronics, medical applications, and adhesives. Photopolymerization has recently expanded into innovative areas such as 3D and 4D printing. While traditionally performed using UV light, recent advances have focused on developing new photo-initiating systems that absorb in the visible and near-infrared (NIR) range, addressing users’ safety concerns and offering new structural possibilities. Due to the potential toxicity associated with transition metal-based initiators,  in both academia and industry, researchers are increasingly focusing on organic photo-initiators. Moreover, fundamental photochemistry is also involved in the investigation of photopolymerization, such as electron transfer, intersystem crossing, and photolysis.

Innovation in the discipline of photopolymerization has led to the creation of novel photosensitive resins through the careful selection and combination of photo-initiators, monomers, oligomers, additives, and fillers. These resins are being adapted for new applications, including 3D/4D printing, composite manufacturing, and biomedical devices. In support of this rapidly evolving field, Polymers invites submissions to a Special Issue titled “Advances in Photopolymer Materials,” which welcomes research articles and reviews related to the development of novel photo-initiators, photosensitive formulations, and photopolymer-based materials. Studies on the comprehension of photoinduced mechanisms under light exposure using Electron Paramagnetic Resonance, laser flash photolysis, or fluorescence are also welcome.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

The photoinitiation properties of two porphyrins were evaluated for the free-radical photopolymerization (FRP) of a bio-based acrylated monomer, i.e., soybean oil acrylate (SOA). Their combination with various co-initiators, such as a tertiary amine as electron donor (MDEA), an iodonium salt as electron acceptor (Iod), as well as two biosourced co-initiators used as H-donors (cysteamine and N-acetylcysteine), makes them highly efficient photoinitiating systems for FRP under visible light irradiation. Electron paramagnetic resonance spin trapping (EPR ST) demonstrated the formation of highly reactive radical species, and fluorescence and laser flash photolysis highlighted the chemical pathways followed by the porphyrin-based systems under light irradiation. High acrylate conversions up to 96% were obtained with these different systems at different irradiation wavelengths (LEDs@385 nm, 405 nm, 455 nm, and 530 nm), in laminate or under air. The final crosslinked and bio-based porphyrin-based materials were used for the full photo-oxidation in water of an azo-dye (acid red 14) and under UV irradiation. These materials have been involved in three successive depollution cycles without any reduction in their efficiency. Full article
