“…This result was expected as it was hypothesized that increasing the initiator concentration would subsequently increase the number of radicals generated for the polymerization reaction. 36,43 This radical increment was able to compensate for the radicals quenched by oxygen, permitting cross-linking of the Gel-MA macromers. A similar approach has been implemented by Melchels et al where biofabricated Gel-MA/gellan gum constructs were UV irradiated while being immersed in a photoinitiator bath to prevent loss of radicals due to oxygen inhibition.…”

Oxygen inhibition is a phenomenon that directly impacts the print fidelity of 3D biofabricated and photopolymerized hydrogel constructs. It typically results in the undesirable physical collapse of fabricated constructs due to impaired cross-linking, and is an issue that generally remains unreported in the literature. In this study, we describe a systematic approach to minimizing oxygen inhibition in photopolymerized gelatin-methacryloyl (Gel-MA)-based hydrogel constructs, by comparing a new visible-light initiating system, Vis + ruthenium (Ru)/sodium persulfate (SPS) to more conventionally adopted ultraviolet (UV) + Irgacure 2959 system. For both systems, increasing photoinitiator concentration and light irradiation intensity successfully reduced oxygen inhibition. However, the UV + I2959 system was detrimental to cells at both high I2959 concentrations and UV light irradiation intensities. The Vis + Ru/SPS system yielded better cell cyto-compatibility, where encapsulated cells remained >85% viable even at high Ru/SPS concentrations and visible-light irradiation intensities for up to 21 days, further highlighting the potential of this system to biofabricate cell-laden constructs with high shape fidelity, cell viability, and metabolic activity.

“…Although the immobilization process varies from case to case, it usually involves solvent‐casting, UV‐induced crosslinking or physical gelation . UV‐curable polymeric coatings are always in competition with thermally curable waterborne, solvent‐borne or powder coatings . In general, the UV curing process is mainly determined by the desired applications of the coating materials .…”

(Meth)acrylated poly(ethylene glycol)s as precursors for rheology modifiers, superplasticizers and electrolyte membranes: a review

This review summarizes current trends in (meth)acrylated poly(ethylene glycol) (PEG) systems in the last decade, with a specific focus on their most important applications, including associative rheology modifiers, superplasticizers and electrolyte membranes. Associative rheology modifiers based on (meth)acrylated PEGs have significantly contributed to improvement of the application characteristics of waterborne coatings. These materials are employed by paint formulators to provide proper viscosity profiles across an entire shear range encountered in various paint applications. In the cement and concrete industry, superplasticizers derived from (meth)acrylated PEGs have also opened the doors to advances in this area, because of their ability to produce cementitious materials with lower water content and without compromising workability. In addition, development of solid electrolyte membranes based on photo-curable (meth)acrylated PEGs for use in polymer lithium ion batteries has recently attracted increasing attention in the energy storage industry. This review provides a comprehensive overview of the structural investigations and applications of (meth)acrylated PEGs and serves as a starting point for future studies.Over the past few decades, one of the major challenges in the energy storage industry has been developing solid electrolytes

A novel cyclohexane derivatized soybean oil (CSO) is synthesized by Diels–Alder cycloaddition of soybean oil with isoprene. Then, the epoxidized cycloaliphatic soybean oil (ECSO) is prepared via epoxidation of CSO. For comparison purpose, norbornylized soybean oil (NSO) and epoxy norbornane soybean oil (ENSO) are synthesized. The CSO, ECSO, NSO, and ENSO are characterized by1H NMR,13C NMR, gradient heteronuclear single quantum correlation (gHSQC) 2D NMR, and mass spectroscopy. The epoxidized soybean oil (ESO), ECSO, and ENSO are photopolymerized using UV‐light, and the kinetics of the photocuring reactions is evaluated by real‐time Fourier transform infrared (FT‐IR) and photo‐differential scanning calorimetry (DSC). Real‐time FT‐IR and photo‐DSC indicate the improved reactivity of ECSO and ENSO compared to ESO. It is found that the curing rate and final conversion of novel developed ECSO is higher than ESO, but lower than ENSO.
