Summary: The effect of urea derivatives (UDs) on volume shrinkage during the curing process of BAGE/DCBE/PAH was studied. UDs with N-H bonds and bulky substituents effectively reduced the volume shrinkage. Before curing, UDs were dispersed in the composition, but after curing, they dissolved in the cured compounds due to collapse of dense packing based on hydrogen bonding and/or p-stacking. Furthermore, the curing behavior and structure of the cured materials were analyzed using DSC and IR. The results showed that UDs had minimal impact on the curing of the DCBE/BAGE/PAH system.

Summary: This study discusses the kinetics of fast thermal curing epoxy resin and the fast-curing ability initiated by 4-hydroxyphenyl dialkyl sulfonium salt cationic curing agent. It is found that the curing reaction is driven by two chain propagation mechanisms, with different curing rates at different stages of polymerization. The activation energy of the mechanisms is also influenced by the content of the curing agent. By optimizing the formulation and process, the epoxy system can be cured in just a few seconds.

Summary: The scientific community is actively researching bio-based derivatives to reduce the consumption of fossil-based materials and their environmental impact. Developing bio-based plastics is a significant challenge in achieving sustainability and a green economy. A study focused on using a bio-based monomer, isosorbide, for the production of bio-based resins used in coatings. They successfully functionalized isosorbide to introduce epoxy groups, which were then activated through UV radiation for cross-linking. The bio-based resin showed potential for UV-cationic curing, reaching conversion rates above 85%. Additionally, they added a bio-based filler, macadamia nutshell powder (MAC), to increase the surface hardness of the coating. The resulting coating with 30% MAC showed a significant increase in hardness compared to the pristine bio-based epoxy resin. Thermo-mechanical analysis revealed that the addition of MAC also increased the glass transition temperature (Tg) of the coating.

Summary: The development of a novel technique using photopolymerization to obtain PDMS membranes provides a fast and simple solution to the worldwide challenge of oil removal from water. The high reactivity of the acrylated PDMS formulation in photo-induced free radical polymerization is evaluated using differential scanning photo-calorimetry. Two types of membranes, dense or porous, are developed and studied, with the porous membranes obtained using an environmentally friendly sodium chloride template. The hydrophobic/oleophilic nature of PDMS allows the UV-cured membranes to selectively remove the target oil, dodecane, from water. The dodecane sorption capability of both membranes is investigated and compared, and the membranes can be easily reused by compressing them to recover the adsorbed oil. These PDMS sorbents exhibit high mechanical stability after five adsorption/desorption cycles.

Summary: In this work, a diglycidyl furfuryl amine (DGFA) was synthesized to produce a functional coating. A room temperature curing process, using bio-based itaconic acid (IA), was implemented to reduce energy consumption. The curing process was characterized using DSC, rheology, and real-time ATR FTIR, while the thermo-mechanical properties were analyzed using DMTA. Finally, the surface properties of the coating were modified via a UV-induced thiol-ene reaction between itaconic acid moieties and fluorine-based monomers. The surface functionalization was evaluated using contact angle measurements and XPS analysis.

Summary: Corrosion is a significant problem for steel, and research has focused on developing effective corrosion prevention strategies. Commonly used corrosion inhibitors can be harmful, so there is interest in finding natural alternatives. Polyphenols, derived from plants or agricultural by-products, have been investigated for their rust conversion and corrosion prevention properties. This review discusses the use of polyphenols as rust converters, in green anticorrosive coatings, and as active components in corrosion-inhibiting primers. Polyphenolic additives in coatings are also explored as sustainable systems to improve corrosion resistance.

Summary: In order to move towards a circular bioeconomy, a paradigm shift from traditional petroleum-based non-recyclable thermosets to biobased repeatedly recyclable materials is required. Two mechanically and chemically recyclable extended vanillin-derived epoxy thermosets were successfully fabricated by introducing Schiff-base/imine covalent dynamic bonds. These thermosets exhibited good thermal and mechanical properties, stability in common organic solvents, and the ability to be thermally reprocessed through compression molding. Furthermore, they could be rapidly and completely chemically recycled to water-soluble aldehydes and amines by imine hydrolysis in 0.1M HCl solution.

Summary: This study presents a novel approach for fabricating bioactive glass reinforced scaffolds using 3D printing technology. The composite scaffold, made from a bio-based acrylate resin derived from soybean oil and a reactive diluent called isobornyl acrylate, showed improved mechanical behavior compared to traditional mould-synthetized samples. The addition of bioactive glass particles did not significantly affect the curing process or the cytocompatibility of the scaffold, but resulted in higher metabolic activity and increased cell attachment on the scaffold surfaces.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.
