Special Issue Information

Dear Colleagues,

Photopolymerization, with its ability to form complex structures and intricate designs through light-induced reactions, is a cornerstone for advanced material fabrication. This process not only enables the creation of highly detailed patterns and geometries but also allows for the precise control over the properties of the resulting materials. Such precision is critical in fields where high material performance is required. Photopolymerization reactions are commonly used in the production of various types of coatings (e.g., paints, lacquers, inks), adhesives, dental fillings, hydrogels, and smart materials, as well as in electronics, optics, 3D printing, and many other applications. The potential to further develop this technology is huge.

The scope of this Special Issue, titled “Photopolymerization: Materials, Applications and Challenges”, is to present recent advances in the design of novel photoinitiating systems, including the synthesis of novel photopolymerizable monomers and photoinitiators, and the improvement of photopolymerization technology.

Three novel bio-based monomers were synthesized through an amidation reaction involving allylated derivatives of coumaric, ferulic and phloretic acid and a diamine obtained from a thiol-ene coupling reaction between limonene and cysteamine. The monomers containing the enone bond of the cinnamic moiety underwent photoisomerization and photocycloaddition reactions upon UV light irradiation. All three monomers were photocured via thiol-ene photopolymerization using a glycerol-derived trifunctional thiol, resulting in fully bio-based poly(amide–thioether)s. The polymers derived from monomers that contain the enone bond exhibited glass transition (Tg) temperatures of 85 °C when a stoichiometric ratio of the thiol was used, whereas polymers in which an excess of thiol was used exhibited Tg temperatures of 61 and 74 °C. The higher Tg of the synthesized polymers, compared with other reported polymers produced from thiol-ene photopolymerizations, was attributed to the combination of the aromatic rings of the cinnamic moiety and the cycloaliphatic ring of limonene, as well as the presence of the amide groups in the polymer, which can induce hydrogen bonding. The development of high Tg polymers from bio-based monomers through thiol-ene photopolymerization represents a significant advancement in the polymer synthesis sector, offering an improved performance and sustainability.
