Summary: Novel fluorinated aromatic imide-modified urethane acrylate oligomers (FI-UAs) with different flexible methylene chain lengths were successfully synthesized in this study. UV-curable optically clear resins (OCRs) were prepared using these oligomers. The curing behavior, thermal and optical properties, as well as adhesion properties of the cured films were investigated. The results showed that the cured films had improved thermal and optical properties, along with increased adhesion and haze with longer methylene chain lengths of FI-UA oligomers.

Summary: This study synthesized four model urethane acrylates with different functionalities and studied them using different energy-equivalent irradiation methods. Results showed that EB-cured samples had higher curing degree than UV-cured samples under equivalent energy, and in situ polymerization effect of EB irradiation could produce higher curing degree. The performance of cured films and coatings was affected by multiple factors such as functionality, irradiation type and energy supply mode.

Summary: This study investigated an environmentally-friendly synthesis method for bio-based polyester acrylate, which is useful for UV-curable coatings. Itaconic acid and ethoxylated diglycerol were used as bio-based moieties. Although the radical copolymerizability of itaconoyl groups with acryloyl groups has not been fully proven, it is expected that introducing itaconoyl groups into polymer side chains would enhance the cross-linking density. On the other hand, ethoxylated diglyceryl moieties contribute to rapid UV-curing and yield cross-linked polymer due to their multifunctionalities. The manufacturing process in this study resulted in less wastewater discharge and allowed the conversion of the neutralized aqueous layer into a waterborne coating.

Summary: This study presents a novel method to create a UV-curable nanocomposite coating with exceptional corrosion resistance. Modified graphene oxide was introduced to improve the dispersion and interaction with the resin matrix. The addition of a suitable amount of graphene oxide resulted in a significant reduction in film porosity, improved resistance to ionic current and charge transfer. However, excessive loading of graphene oxide could potentially harm the corrosion resistance properties of the coating.

Summary: In the process of free radical UV curing, the surface of cured materials often retains a significant amount of acryl groups due to oxygen inhibition. These acryl groups can be utilized for surface modification through aza-Michael addition reactions. By using various amino compounds, the hydrophilicity and affinity of oxygen-inhibited surfaces can be improved, leading to diverse surface properties after modification.

Summary: We report the growth and photophysical characterization of two polar hybrid lead halide phases, methylenedianiline lead iodide and bromide, (MDA)Pb2I6 and (MDA)Pb2Br6, respectively. The noncentrosymmetric crystal structure of these phases leads to highly oriented molecular dipole moments, resulting in second harmonic generation (SHG) upon excitation at 1064 nm. The size dependence of the SHG signal indicates that the bromide exhibits a stronger phase-matching response while the iodide exhibits a significantly weaker non-phase-matching signal. Fluorescence from (MDA)Pb2Br6 is observed around 630 nm below 75 K, whereas (MDA)Pb2I6 exhibits very weak luminescence. The contrasting optical properties are attributed to differences in the character of the halide sublattice, with the increased polarizability of the iodide ions reducing the local electric field in the crystals.

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: Surface-enhanced Raman optical activity (SEROA) has been extensively studied for its ability to directly probe the stereochemistry and molecular structure. This study presents a strategy for achieving a similar effect by coupling optically inactive molecules with the chiral plasmonic response of metasurfaces, resulting in a surface-enhanced Raman polarization rotation effect. This technique extends the potential of Raman optical activity to inactive molecules and enhances the sensitivity performances of surface-enhanced Raman spectroscopy, without the heating issue present in traditional plasmonic-enhanced ROA techniques.

Summary: The effect of processing method and sepiolite filler amount on the microstructure of starch-based nanocomposites was investigated. The processing method disrupted the rigid lattice structure of semicrystalline starch, resulting in amorphous flexible films with high transparency and good thermal resistance. The microstructure of the bio-nanocomposites depended on complex interactions among sepiolite, glycerol, and starch chains, which also affected the final properties of the composite materials.

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: 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.
