Xia, Mengling published the artcileCompact and large-area perovskite films achieved via soft-pressing and multi-functional polymerizable binder for flat-panel X-ray imager, Product Details of C15H20O6, the publication is Advanced Functional Materials (2022), 32(16), 2110729, database is CAplus.

Thanks to its strong X-ray absorption and large carrier diffusion length, perovskites have demonstrated excellent performance for X-ray detection. Combination of perovskite with thin-film transistor (TFT) arrays to construct flat-panel X-ray imager (FPXI) is required for X-ray imaging, yet this is rarely reported. Solution processing of perovskite thick film onto TFT can enable the electronic connection, however the amounts of pinholes inevitably form during the solvent evaporation and result in a porous film with deteriorated performance and stability. Here a novel strategy is raised to achieve high-quality perovskite thick films for TFT integration via soft-pressing and in situ polymerization of multi-functional binder (TMTA). The combined process largely eliminates the pinholes, improves the surface smoothness, passivates grains boundaries, reduces ionic migration, and improves stability. Accordingly, a compact and smooth MAPbI₃ thick film integrating with TFT arrays is prepared for flat-panel X-ray imaging. The largest film (28 x 28 cm²) is obtained with the state-of-the-art performance (ratio of sensitivity to noise current: 1.41 x 10¹¹ μC Gy^-1 A^-1) among polycrystalline films. It is hoped that the work provides guidance for fabricating compact perovskite thick films and push perovskite FPXI one step further for low-dose X-ray imaging.

Yao, Xinle published the artcile3D printing of PTFE-filled polyimide for programmable lubricating in the region where lubrication is needed, Safety of Trimethylolpropane triacrylate, the publication is Tribology International (2022), 107405, database is CAplus.

Three-dimensional (3D) target-region-lubrication printing of photosensitive polyimide (PSPI) filled with polytetrafluoroethylene (PTFE), i.e., PSPI-PTFE, with excellent tribol. properties for self-lubricating devices was realized by digital light processing of PSPI-PTFE ink and thermal post-treatment. The 3D-printed PSPI-PTFE composites exhibited the friction coefficients and wear rates sharply reduced by 88% and 98%, resp., and good mech. properties, thermal stability and interlayer bonding as well. Importantly, the surfaces with lubricating only in regions where needed were readily realized due to the layer-by-layer manufacturing manner of 3D printing. As proof-of-concept, a target-region-lubricating bearing was demonstrated successfully, which run stably with a speed ranged from 60 to 180 rpm/min, indicating that the 3D-printed PSPI-PTFE composites are suitable for fabricating devices with complex and special shapes.

Korrapati, Vinodh K. published the artcileBilayer coatings for temporary and long-term corrosion protection of magnesium-AZ31 alloy, Formula: C15H20O6, the publication is Progress in Organic Coatings (2022), 106608, database is CAplus.

Phosphate and silane containing organic self-assembled (SA) layers serve as pre-treatments on magnesium alloy sheet materials. A reliable protection was achieved in this work via application of alkyd-based coatings on the pretreated surface. The idea of adopting SA pre-treatments as functional layers at metal-polymer interface is to influence the adhesive properties between solid metal substrate and alkyd-based coating. Hexadecyltrimethoxysilane (HDTMS) deposited metal surfaces exhibit stronger adhesive strength, while a near homogeneous distribution of the octadecylphosphonic acid (ODPA) and perfluorodecylphosphonic acid (PFDPA) exhibit low adhesive phenomenon, when placed as pre-layers in bilayer coatings. Electrochem. impedance results after 168 h of immersion reveal that the organophosphate and organosilane deposited bilayer films demonstrate protective properties with almost no interface defects. Moreover, organophosphate treated bilayer coatings enhance easy peeling of alkyd coat after protecting the surface from corrosive electrolytes. Bilayer coatings developed on AZ31 sheets can confer temporary or long-term corrosion protection depending on further processing strategy and offer efficient alloy protection for both purposes.

Gao, Yuan published the artcileFrontal Polymerization of Thin Layers on a Thermally Insulating Substrate, Recommanded Product: Trimethylolpropane triacrylate, the publication is ACS Applied Polymer Materials (2022), 4(7), 4919-4927, database is CAplus.

Motivated by the use of frontal polymerization for the manufacturing of thin layers with thickness down to 1̃00μm, we numerically and exptl. investigate the interplay between the exothermic polymerization and the heat losses to the substrate. The results show how the reaction-diffusion power balance affects the velocity and temperature of the polymerization front. The lower thickness limit of the thin layer depends on the cure kinetics of the resin and the thermal properties of the substrate and is described by a scaling law. Concurrently, thin-layer frontal polymerization experiments confirm the effects of front-substrate interaction on the front propagation and the limiting thickness of the polymerized layer. The present study offers a fundamental understanding of the resin-substrate interplay in thin-layer frontal polymerization and provides a quant. description of the limiting thickness of the layer in the fabrication of functional thin polymeric parts and resin coatings.

Li, Guo-Xing published the artcileA microfluidics-dispensing-printing strategy for Janus photonic crystal microspheres towards smart patterned displays, Recommanded Product: Trimethylolpropane triacrylate, the publication is Journal of Polymer Science (Hoboken, NJ, United States) (2022), 60(11), 1710-1717, database is CAplus.

From the implementation point of view, the printable magnetic Janus colloidal photonic crystals (CPCs) microspheres are highly desirable. Herein, we developed a dispensing-printing strategy for magnetic Janus CPCs display via a microfluidics-automatic printing system. Monodisperse core/shell colloidal particles and magnetic Fe₃O₄ nanoparticles precursor serve as inks. Based on the equilibrium of three-phase interfacial tensions, Janus structure is successfully formed, followed by UV irradiation and self-assembly of colloid particle to generate magnetic Janus CPCs microspheres. Notably, this method shows distinct superiority with highly uniform Janus CPCs structure, where the TMPTA/Fe₃O₄ hemisphere is in the bottom side while CPCs hemisphere is in the top side. Thus, by using Janus CPCs microspheres with two different structural colors as pixel points, a pattern with red flower and green leaf is achieved. Moreover, 1D linear Janus CPCs pattern encapsulated by hydrogel is also fabricated. Both the color and the shape can be changed under the traction of magnets, showing great potentials in flexible smart displays. We believe this work not only offers a new feasible pathway to construct magnetic Janus CPCs patterns by a dispensing-printable fashion, but also provides new opportunities for flexible and smart displays.

Zhang, Peng published the artcileUV Curable Robust Durable Hydrophobic Coating Based on Epoxy Polyhedral Oligomeric Silsesquioxanes (EP-POSS) and Their Derivatives, Recommanded Product: Trimethylolpropane triacrylate, the publication is ACS Omega (2022), 7(20), 17108-17118, database is CAplus and MEDLINE.

Hydrophobic coatings have considerable potential applications in many fields. Easy-to-operate and high durability are essential for practical use, fast cured and solvents-free are plus, and if possessed of characteristics (antigraffiti, good adhesion, high hardness, heat resistance, wide range of applicability, etc.) at the same time, which is a dream solution Herein, a facile one-step approach with the above features was reported for a UV curable robust hydrophobic coating based on Epoxy Polyhedral Oligomeric Silsesquioxanes (EP-POSS). The structure and surface morphol. of these EP-POSS and their derivatives were systematically studied. Because of the core-in-cage structure which was constructed by repeating units R-Si(O_1/2)₃– and the strong covalent bond of Si-C and Si-O, the coatings displayed high pencil hardness (6-8H), high thermal stability with initial decomposition temperature around 350-400°C, and high water contact angle (up to 108.06°) even after outdoor exposure for a month. These POSS and their derivatives are expected to find uses in various applications such as stain resistance, self-cleaning, scratch resistance, and cigarette moxibustion resistance of wood furniture, kitchenware, medical and industrial appliances.

Barkane, Anda published the artcileSimultaneous wettability and stiffness control of UV-curing vegetable oil resin composites by lignocellulosic components, HPLC of Formula: 15625-89-5, the publication is Polymer (2022), 125154, database is CAplus.

Acrylic resins have various applications, which range from coatings to 3D printing, among others. Following green chem. and environmental preservation trends, the demand for bio-based acrylic resins is growing. Vegetable oil-based resins have arisen to meet the present challenge. However, the performance and tuning of sustainable resin properties still need improvement. Hence, we undertook this study to research tuneable and durable vegetable oil-based UV-curing composite resins. This work reports on vegetable oil-based resin loaded with lignocellulosic components of cellulose nanocrystals (CNC), cellulose nanofibres (CNF), hemicellulose (HC), and lignin (LN). The effects of lignocellulosic components on thermal stability, thermomech. properties, transparency, surface morphol., and wettability were evaluated in detail. In addition, the interaction of lignocellulosic components with the polymer matrix and interface was thoroughly investigated. The intense interaction between lignocellulosic components and the polymer matrix helps to form a strong interface and creates a polymer composite with enhanced thermomech. properties. The composite surface morphol. and wettability can be tuned depending on the lignocellulosic component, i.e., with the addition of HC, CNC, and CNF. Hydrophilic affinity is improved and water wetting angles as low as 8° can be achieved, but with LN a value of 96° was observed, a slight increase in hydrophobicity compared to the vegetable oil (VO) matrix value of 90°. Adding HC and CNC reduced transparency at 500 nm by 14 and 16%, while adding LN and CNF by 18 and 25%, resp. Fourier-transform IR spectroscopy revealed strong interfacial interactions through the hydrogen bonding between CNC, CNF, HC, and the VO polymer. This work will shed light on the lignocellulosic components’ future role in UV-curing resin applications. It also broadens lignocellulosic particles’ application as reinforcing additives for UV-light sensitive polymeric resins.

Sun, Ke published the artcileSunlight Induced Polymerization Photoinitiated by Novel Push-Pull Dyes: Indane-1,3-Dione, 1H-Cyclopenta[b]Naphthalene-1,3(2H)-Dione and 4-Dimethoxyphenyl-1-Allylidene Derivatives, Computed Properties of 15625-89-5, the publication is Macromolecular Chemistry and Physics (2022), 223(4), 2100439, database is CAplus.

The free radical polymerization of acrylates photo-initiated by push-pull dye-based photoinitiating systems (PISs) is widely studied in previous works. As a supplementary study on push-pull dyes, here in this article, 25 push-pull structures comprising electron acceptors derived from indane-1,3-dione and 1H-cyclopenta[b]naphthalene-1,3(2H)-dione (series 1) and 4-dimethoxyphenyl-1-allylidene moieties (series 2) and various electron donors are synthesized and examined as innovative structures for photoinitiation. Among the 2 series of dyes examined in this work and by monitoring the polymerization processes by RT-FTIR measurements, 4 dyes are determined as exhibiting excellent photoinitiation performances and these dyes are selected to perform further studies concerning the chem. mechanisms occurring inside the 3-component PISs, for example, steady state photolysis, fluorescence quenching measurements, and cyclic voltammetry. Markedly, their reactivity is also proved by photoinitiation performance upon sunlight. These results prompt one to develop high performance push-pull dyes as photosensitizers and sunlight can be used as a mild and ecofriendly light source, which can advantageously replace LEDs for the free radical photopolymerization in the future. Finally, the formation of 3-dimensional patterns with an excellent gradient of resolution is successfully achieved by the direct laser write (DLW) with/without SiO₂ fillers.

Pagidi, Srinivas published the artcileNanosize-confined nematic liquid crystals at slippery interfaces of polymer composites consisting of poly(hexyl methacrylate), Application of Trimethylolpropane triacrylate, the publication is Journal of Molecular Liquids (2022), 118540, database is CAplus.

Nanosize-confinement of anisotropic mol. arrangement below the wavelength of visible light gives fascinating and useful optical and phys. properties. Liquid crystal (LC) and polymer composite is one of the most well-known combinations to explore such effect for applications from optical modulating devices to sensors. The nanosize-confinement, however, causes inevitably strong surface interaction, which requires high-operating voltage to reorient LC directors. Herein, we demonstrate nanosize-confined LCs embedded in photopolymerizable polymer composites including poly(hexyl methacrylate) (PHMA) with glass transition below room temperature, which can provide slippery interfaces owing to weak anchoring strength. Using the slippery interface in the nanosize-confined electro-optic device gives highly improved electro-optic properties: up to, resp., 41.1% and 22.2% reduced threshold and operating elec. field strength and up to 57.3% enhanced transmittance compared to those without PHMA. We believe this approach, providing a slippery interface in LC-polymer composites, will contribute to practical realization of optically isotropic-to-anisotropic switching mechanisms for next-generation optical modulation devices.
