Based on photochromism of a diarylethene species, we introduced an easy but highly effective bar-coating method of a photochromic ink including shell type of photochromic pigments and UV curable epoxy resin, reversibly presenting change color in response to UV light. By using mask patterns for bar-coating, different patterns were successfully coated on various types of surfaces such as wood, glass, general concrete wall and even curved surfaces. Besides, in order to increase mech. stability of the coating, thin layer including acrylate chems. is further coated on the patterns. Finally, camouflage coating applications for encryption display films were successfully demonstrated.

Lee, Seok Lyul published the artcileOptically isotropic nano-size encapsulation of nematic liquid crystals with a high-filling factor, Application In Synthesis of 15625-89-5, the publication is Journal of Molecular Liquids (2022), 119254, database is CAplus.

The filling factor of LCs in the LC-polymer composite system is a crucial factor for the electro-optic performance of optically isotropic liquid crystal (OILC) devices. The polymerization-induced phase separation method is well-known method to fabricate the OILCs; however, this method spontaneously limits the filling factor by ∼ 40%, which is inadequately low, owing to low-LC concentration in the mixtures To overcome such intrinsic problem, we propose an encapsulated LC which is fabricated by means of oil-in-water encapsulation. Through this approach, the filling factor of LCs is effectively increased up to 67.8% because the capsules are closely packed. Consequently, we achieve a thin-composite film of nano-size LC encapsulation whose isotropic state is reliably switched to anisotropic state in response to an external elec. field with low-operation voltage (E_th = 1.4 V/μm and E_op = 4.6 V/μm), fast-response time (τ_on = 0.5 ms, τ_off = 2.2 ms), and hysteresis-free electro-optic behavior. The highly improved electro-optic performances of the proposed encapsulated LC device would give versatile applications in blooming free-form flexible displays and various tunable photonic systems.

Cho, Youngsung published the artcileEffects of two silane surface modifications with different functional groups on the thermal conductivity and mechanical properties of UV-cured composites with high ceramic filler loading, Quality Control of 15625-89-5, the publication is Ceramics International, database is CAplus.

With rapid technol. advancements, efficient thermal management is becoming increasingly important to sustain the stable operation of electronic devices. In this study, aluminum nitride (AlN) fillers with various acrylate monomers were subjected to two types of silane surface treatments to prepare composites with a high loading of AlN filler (65 wt%). The acrylates-isobornyl acrylate (IBOA), 1,4-butanediol diacrylate (BDDA), and trimethylolpropane triacrylate (TMPTA)-were mixed with bisphenol A ethoxylate dimethacrylate (Bis-EMA) as an oligomer, and phenylbis (2,4,6-trimethylbenzoyl)phosphine oxide (BAPO) as a photo-initiator in different proportions to obtain resin matrixes. Pristine AlN and AlN functionalized with APTES and MPS were used as fillers. The effect of the acrylate functional group in silanes on the thermal and mech. properties of the acrylate resin was explored. The thermal conductivities of the IBOA/AlN/APTES and IBOA/AlN/TMPTA composites with a high loading of the filler functionalized with APTES and MPS were 1.34 and 1.57 W/(m•K), resp., 4.15 and 5.28 times higher than that of the composite with neat resin. The enhanced filler-matrix compatibility increased the tensile strength of the composites. The findings highlighted that silane functionalization of AlN can enhance the thermal conductivity and mech. properties of the composite.

In the present work, a novel electrochem. sensor modified glassy carbon electrode with ion-imprinted polymers (IIP-GCE) was applied for uranyl ions (UO²⁺²) determination Surface modifier was synthesized through precipitation polymerization method, using acrylic acid as a monomer, benzoyl peroxide (BPO) as initiator, and trimethylolpropane triacrylate (TMPTA) as crosslinker. A new uranyl-trans-3-(3-pyridyl) acrylic acid complex was employed, serving as an active and specific site on the synthesized modifier. Next, the synthesized modifier was characterized using X-ray diffraction (XRD), SEM (SEM), and Fourier Transform IR Spectroscopy (FT-IR) techniques. UO²⁺² ions were detected using a differential pulse adsorptive anodic stripping voltammetry method. Under the optimized conditions (pH = 8.0, pre-concentration time = 10 min and pre-concentration potential = -0.30 V), the modified electrode exhibited linear behavior in the interval of 1.27-95.49μg.L^-1 with a limit of detection (LOD) of 0.43μg.L^-1. Also, the constructed ion-imprinted sensor showed a successful application for determining UO²⁺² ions with recovery range of 97.6-101% in real samples.

Wu, Yinping published the artcileLarge-molecular-weight acyldiphenylphosphine oxides as low-mobility type I photoinitiator for radical polymerization, HPLC of Formula: 15625-89-5, the publication is European Polymer Journal (2022), 111380, database is CAplus.

In recent years, the light source for photopolymerization technol. is evolving from energy-hungry mercury lamps to the safer light-emitting diodes (LEDs), and it is urgent to develop new photoinitiator adapted to the photopolymerization system with LED light source. Some acyldiphenylphosphine oxide photoinitiators have been designed and developed for LED light source, but their application is severely limited in the fields of food packing, medical equipment, environmentally-friendly product, etc. due to their high mobility in photocured polymers. In this study, eight acyldiphenylphosphine oxide mols. (DAPO-1 ∼ DAPO-8) were synthesized by introducing large mol. weight groups and their UV-visible absorption, photodegradation quantum yield, photopolymerization properties, mobility and solubility in monomer were determined Thereinto, photoinitiators show lower mobility than TPO, the photoinitiator commonly used in industry, as well as good solubility in monomers and excellent photopolymerization performance. Therefore, they can serve as potential substitutes for com. TPO, especially in the application of low-migration photocurable system.

Liu, Xuesheng published the artcileIn situ Growth of UiO-66 with Its Particle Size Reduced by 90% into Porous Polyacrylate: Experiments and Applications, Application In Synthesis of 15625-89-5, the publication is Industrial & Engineering Chemistry Research (2022), 61(23), 7902-7910, database is CAplus.

In this study, we successfully synthesized a novel composite material UiO-66/polyacrylate (UiO/PA) by suspension polymerization and in situ growth of metal-organic frameworks (MOFs). Due to the control of heterogeneous nucleation and firm growth, nano-UiO-66 with a diameter of only 400 nm has been reduced by about 90%, resulting in lower transfer resistance, effective separation of photogenerated carriers, and more catalytic active sites exposed. Under visible light irradiation, UiO/PA with 48.7% loading can almost completely degrade rhodamine B (RhB) in 120 min and the corresponding degradation rate constant of RhB reached 0.0203 min^-1 from 0 min^-1. After easy filtration and five cycles, the degradation rate is still above 85%. This study can provide new insights into effectively improving the photocatalytic performance of MOFs.

Li, Shuang published the artcileProtonic ionic liquids as efficient phase-separation catalysts for esterification of trimethylolpropane and acrylic acid, Product Details of C15H20O6, the publication is Journal of Molecular Liquids (2022), 119403, database is CAplus.

Trimethylolpropane acrylate (TMPTA) is becoming an important organic chem. intermediate, but it’s synthesis through the acid-catalyzed esterification of trimethylolpropane and acrylic acid is a challenge due to the poor activity and catalyst separation problems. In this work, a series of 1,3-propanesultone (PS)-functionalized imidazole ionic liquids (ILs) are prepared and evaluated as the acid catalysts for this reaction, including the catalytic performance comparison, optimization of reaction conditions, and the catalytic reusability. The obtained H₂SO₄-based IL ([IMPSH]HSO₄) caused a phase-separation catalytic process (reacted as a homogeneous catalyst, but precipitated at the end of reaction like a heterogeneous catalyst), presenting the best trimethylolpropane conversion (100%) and TMPTA selectivity (86.4%). Such catalytic performance is even better than that of homogeneous H₂SO₄. Moreover, the catalyst can be steadily reused at least four times without obvious change in activity and its structure. The highly efficient and environmentally benign performance of [IMPSH]HSO₄-catalyzed esterification of trimethylolpropane and acrylic acid make it possible to achieve industrial applications.

Hwangbo, Hyeonwoo published the artcileDigital light processing 3D printing of multi-materials with improved adhesion using resins containing low functional acrylates, Formula: C15H20O6, the publication is Korean Journal of Chemical Engineering (2022), 39(2), 451-459, database is CAplus.

Abstract: Digital light processing (DLP) 3D printing has received increasing attention due to high-resolution printing capability, mass productivity, and cheap equipment cost. Most of all, the layer resolution less than 50μm overwhelms 200-300μm layer resolution of its competitive technol., filament deposition modeling (FDM) 3D printing. One of the easiest ways to improve mech. property is the use of multi-materials that complement each other’s weak property However, DLP 3D printing of multi-material printouts with reliable adhesion has been largely unexplored. In this study, we compared the mech. properties of four pairs of multi-materials consisting of two different materials of the same thickness. A composition with highest modulus and ultimate strength was fixed as the first half layer, and the acrylate of the composition for the other half layer was modulated with a monomer having a functionality between 1 and 3. If the acrylate monomer’s functionality for the other half layer was less than three, the multi-material printout showed nearly averaged mech. property of each material. We speculate that low functional acrylate with lower viscosity allows sufficient polymerization at the interface, enabling reliable adhesion. This approach that enables successful multi-material printing with improved adhesion and complementary mech. properties will extend the use of DLP 3D printing in a broad range of industrial application that requires both sophisticated shape and mech. strength.

Lee, Zhong-Han published the artcileEffect of the Steric Hindrance and Branched Substituents on Visible Phenylamine Oxime Ester Photoinitiators: Photopolymerization Kinetics Investigation through Photo-DSC Experiments, Computed Properties of 15625-89-5, the publication is Photochemistry and Photobiology (2022), 98(4), 773-782, database is CAplus and MEDLINE.

In this work, free radical photopolymerization (FRP) kinetics for series of different phenylamine oxime ester structures (DMA-P, DEA-P, DMA-M, TP-2P, TP-2M and TP-3M) was investigated. Steric hindrance and branched substituents were prepared to realize the corresponding electronic and photopolymerization effects. The photophys., electrochem., thermal properties and radical concentration were investigated by UV-visible spectroscopy, cyclic voltammetry (CV), thermogravimetric anal. (TGA), differential scanning calorimetry (DSC) and ESR (EPR). Furthermore, the structure-reactivity relationships were also studied in detail through photo-DSC experiment We demonstrate that the introduction of alkyl chains and/or numbers of oxime esters affects significantly the photoreactivity. Under the same weight ratio of formulation and irradiated condition, TP-3M containing three oxime esters in its structure and Me group in the periphery exhibits the highest double-bond conversion efficiency. TP-3M-based formulation also shows a wide operation window under different contents and light intensities. Importantly, the photoreactivity of the TP-3M-based system was found to be better than the com. photoinitiator (OXE-01) under LED@405 nm at a low concentration This work could provide some significance to the design of oxime esters with enhanced photoreactivity.

Wang, Yao published the artcileMacrophage-targeting gene silencing orchestrates myocardial microenvironment remodeling toward the anti-inflammatory treatment of ischemia-reperfusion (IR) injury, Safety of Trimethylolpropane triacrylate, the publication is Bioactive Materials (2022), 320-333, database is CAplus and MEDLINE.

Ischemia-reperfusion (IR) injury represents a major cause of myocardial dysfunction after infarction and thrombolytic therapy, and it is closely related to the free radical explosion and overwhelming inflammatory responses. Herein, macrophage-targeting nanocomplexes (NCs) are developed to mediate efficient co-delivery of siRNA against MOF (siMOF) and microRNA-21 (miR21) into myocardial macrophages, cooperatively orchestrating the myocardial microenvironment against IR injury. Bioreducible, branched poly(β-amino ester) (BPAE-SS) is designed to co-condense siMOF and miR21 into NCs in a multivalency-reinforced approach, and they are surface-decorated with carboxylated mannan (Man-COOH) to shield the pos. surface charges and enhance the serum stability. The final MBSsm NCs are efficiently internalized by myocardial macrophages after systemic administration, wherein BPAE-SS is degraded into small segments by intracellular glutathione to promote the siMOF/miR21 release, finally provoking efficient gene silencing. Thus, cardiomyocyte protection and macrophage modulation are realized via the combined effects of ROS scavenging, inflammation inhibition, and autophagy attenuation, which ameliorates the myocardial microenvironment and restores the cardiac function via pos. cellular crosstalk. This study renders promising solutions to address the multiple systemic barriers against in vivo nucleic acid delivery, and it also offers new options for IR injury by manipulating multiple reciprocal bio-reactions.
