By combining biotechnology and chemistry, sustainable and high-performance thermoplastic polyurethanes (TPU) have been (bio)produced from different renewable carbon sources like biomass and plastic waste, in the frame of a circular (bio)-economy. The bioproduction of betulin (cycloaliphatic diol) using engineered baker's yeast (Saccharomyces cerevisiae) has been demonstrated from a model carbon source for plastic waste. Sustainable TPUs were synthesized in a two-step route with betulin as a chain extender (in different amounts), and with methylene diphenyl diisocyanate as an aromatic diisocyanate and different poly(tetrahydrofuran) (PTHF), as a sustainable long polyol, with varying molar masses. A specific study of betulin hydroxyl (OH) groups have been developed. To the best of our knowledge, such reactivities study had never been studied. It clearly shows the lower reactivity of the secondary OH group and the importance of temperature and catalyst content control on the urethane bond formation. The different obtained sustainable TPUs exhibited high thermal stability due to the specific betulin cycloaliphatic structure. TPUs with only high molar masses PTHF have achieved good phase segregation and elastomeric behavior. The sufficient distance among hard segments allowed interactions between them, reducing the affinity between hard and soft segments, with a specific organization based on phase separation. These TPUs offered adequate thermo-mechanical properties and processability, with stiffness and high Young’s modulus, for a large range of potential applications. Taking into account their architectures, the end of life of these sustainable thermoplastics is largely open to physical or chemical recycling approaches.

This study introduces the development of reusable and antimicrobial face mask materials by coating cotton fabric surfaces with electrospun nanofibrous meshes. A waterborne polyurethane (WBPU) polymer, synthesized from biodegradable sources under mild, catalyst-free conditions, served as the primary coating material. The WBPU polymer was combined with poly(2-ethyl-2-oxazoline) (P2Ox), a biocompatible polymer, and its hydrolyzed derivative, poly(2-ethyl-2-oxazoline)-co-poly(ethylene imine) (P2Ox-co-PEI). These polymer blends were electrospun onto cotton fabrics to form nanofibrous meshes in three distinct morphologies: hybrid, Janus, and core–shell. The materials were characterized using comprehensive techniques, including optical and scanning electron microscopy (SEM), mechanical testing (breaking force and elongation), air permeability measurements, and water contact angle-wetting time assessments. The results revealed enhanced material properties, including improved mechanical strength, optimized wettability, and adequate air permeability suitable for protective face masks. Biocompatibility was demonstrated through cell proliferation tests using mouse fibroblasts, showing a 30 % increase in cell growth on the coated fabrics. Antimicrobial efficacy was assessed against Staphylococcus aureus (S. aureus) ATCC 29213 and Candida albicans (C.albicans) ATCC 10231 (100 % inhibition) and antiviral activity against COVID-19 virus SARS-CoV-2 (94.11 % reduction), highlighting the potential for these materials as alternatives to conventional surgical masks. This work underscores the feasibility of creating sustainable, high-performance protective fabrics that combine biodegradability, biocompatibility, and robust antimicrobial properties, offering a promising solution for personal protective equipment in medical and non-medical applications.

Terpene-based acrylic monomers provide a sustainable and environmentally friendly alternative to conventional acrylic monomers. Due to their low volatility, they can be directly used in high-solid UV coating systems. The wide variety of monoterpenes allows for tailoring the properties of the acrylates by selecting the appropriate raw material, enabling them to match or even exceed the performance of petrochemical monomers. Novel monoterpene copolymers, synthesized with limonene-based acrylates and nopol-based methacrylate, demonstrated excellent curing performance, thermal stability, and solvent resistance. The storage and loss moduli of the respective homopolymers of the limonene-based monomers were analyzed through DMA measurements. The results indicated that these monomers yield very hard polymers with a moderate degree of cross-linking. These findings underscore the potential of terpene-based acrylates as versatile, high-performance, and sustainable substitutes for fossil-based monomers in UV-coating systems.

In this study, a synthesis of hyperbranched polyphenylsilsesquioxane–dimethylsiloxane (hb-PPSQ) copolymer via the Piers-Rubinsztajn (PR) reaction has been developed from a PhSi(OEt)₂OSiMe₂H AB₂-type monomer. The hb-PPSQ formation pathway and the influence of reaction conditions (the monomer feed rate, concentration and amount of the monomer, reaction temperature) on the molar mass characteristics of the resulting hb-PPSQs were investigated by ¹H, ²⁹Si NMR, MALDI, FTIR, and GPC techniques. The reaction of the said monomer initially produces cyclic phenylethoxydimethylsiloxane. Further molar mass growth is possible when a fresh monomer is added to the reaction cycle. Thus, EtOSi-end capped hb-PPSQ with a molar mass of 24.5 kDa and DB≈0.5 was obtained. The terminal ethoxy groups of the resulting hb-PPSQ can be modified by the one-pot PR reaction with triorganosilane to give hb-PPSQs with a variety of end groups. In this way, SiMe₂Ph- and SiMe₂Vin-terminated hb-PPSQs were obtained. Their hydrodynamic and thermal properties were studied. These polymers have low glass transition temperatures (∼ −60 °C) along with high onset decomposition temperatures (∼ 400 °C).

本研究以 PhSi(OEt)2OSiMe2H AB2-型单体为原料，通过皮尔斯-鲁宾斯泰因（Piers-Rubinsztajn，PR）反应合成了超支化聚苯硫醚-二甲基硅氧烷（hb-PPSQ）共聚物。通过 1H、29Si NMR、MALDI、FTIR 和 GPC 技术研究了 hb-PPSQ 的形成途径以及反应条件（单体进料速率、单体浓度和用量、反应温度）对生成的 hb-PPSQ 摩尔质量特性的影响。上述单体的反应最初会产生环状苯乙氧基二甲基硅氧烷。当在反应循环中加入新的单体时，摩尔质量有可能进一步增长。这样，就得到了摩尔质量为 24.5 kDa、DB≈0.5 的乙氧基末端封端的 hb-PPSQ。所得 hb-PPSQ 的末端乙氧基可通过与三有机硅烷的单锅 PR 反应进行改性，从而得到具有各种末端基团的 hb-PPSQ。这样就得到了以 SiMe2Ph- 和 SiMe2Vin 为端基的 hb-PPSQ。研究了它们的流体力学和热学特性。这些聚合物具有较低的玻璃化转变温度（∼ -60 °C）和较高的起始分解温度（∼ 400 °C）。

In this study, a novel three-dimensional bio-based superabsorbent hydrogel, SL-P(AA-AMPS)/CMCS, was synthesized via freeze-drying using sodium lignosulfonate (SL) with rigid phenylpropane structures as the bio-based framework, carboxymethyl chitosan (CMCS) enriched with hydrophilic groups (–OH, –COOH, and –NH₂) as the hydrophilic modifier, and acrylic acid (AA) and 2-acrylamido-2-methylpropanesulfonic acid (AMPS) as monomers. Polymerization was initiated by ammonium persulfate (AP) and crosslinked with N,N’-methylenebisacrylamide (MB). The hydrogel’s structure, morphology, and absorption properties were systematically characterized using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Results revealed a uniform porous structure with an average pore size of 5.8 μm. Absorption capacities in deionized water and 0.9 % NaCl solution reached 1132.9 g/g and 127.9 g/g, respectively, surpassing commercial diaper fillers (273.3 g/g and 61.5 g/g) and feminine hygiene products (223.5 g/g and 45.8 g/g). Under pressurized conditions (2068 Pa), absorption values remained high at 125.7 g/g (deionized water) and 24.0 g/g (0.9 % NaCl solution). The hydrogel exhibited exceptional water retention, retaining 88.8 % and 85.8 % of absorbed water after 8 h at 40 °C and 60 °C, respectively. Swelling kinetics followed a pseudo-first-order model (R² > 0.99), achieving equilibrium within 600 s (deionized water) and 60 s (0.9 % NaCl solution). Biodegradation tests demonstrated a 47.5 % degradation rate in soil after 28 days, significantly exceeding that of non-bio-based P(AA-AMPS) (3.7 %). Application tests highlighted superior absorption capacities for artificial urine (82.4 g/g) and blood (179.2 g/g), outperforming conventional hydrogels by 3.3- and 7-fold, respectively.

As one of potential candidates for fabricating high-power dielectric polymer capacitors, polyetherimide (PEI) has been paid much attention. However, energy storage performance of PEI films, especially discharge energy density, has demonstrated notable discrepancies among various studies. The reported maximum discharge energy densities of PEI are still below 7 J∙cm⁻³, and are closely related to the drying procedures. In this work, PEI films were meticulously synthesized via the solution casting method, with focusing on optimizing the drying procedures to enhance their energy storage performance. The PEI films were pre-dried at various temperatures for different durations. The different drying procedures do not cause change in chemical bonds of PEI. The optimized protocol involves a precise pre-drying step at 80 °C for 8 h in vacuum, seamlessly followed by further drying at 200 °C for 12 h. Pure PEI prepared via the optimized drying procedure exhibits the lowest glass transition temperature of 215.69 °C, exceptional breakdown strength of 678 MV∙m⁻¹, and astounding discharge energy density of 8.48J∙cm⁻³, surpassing the majority of previously reported values. The work not only presents an effective simple method for developing high-performance pure PEI films, but also provides some guidance to enhance energy storage performance of polymer materials.

聚醚酰亚胺（PEI）作为制造大功率电介质聚合物电容器的潜在候选材料之一，一直备受关注。然而，聚醚酰亚胺薄膜的储能性能，尤其是放电能量密度，在不同的研究中表现出明显的差异。已报道的 PEI 最大放电能量密度仍低于 7 J∙cm-3 ，这与干燥过程密切相关。在这项工作中，我们通过溶液浇铸法精心合成了聚乙烯醇薄膜，重点是优化干燥程序以提高其储能性能。PEI 薄膜在不同温度下进行了不同时间的预干燥。不同的干燥程序不会改变 PEI 的化学键。通过优化的干燥程序制备的纯聚乙烯醇表现出最低的玻璃化转变温度（215.69 °C）、超强的击穿强度（678 MV∙m-1）和惊人的放电能量密度（8.48J∙cm-3），超过了之前报道的大多数数值。这项工作不仅为开发高性能纯 PEI 薄膜提供了一种有效的简单方法，而且为提高聚合物材料的储能性能提供了一些指导。

Polyolefins (POs) are key materials in industrial applications, and the development of high-performance and high-value-added POs is always a significant and challenging research focus. The major challenge lies in addressing compatibility between non-polar POs and polar functional components. We herein reported a facile strategy to prepare PO-based nano-objects using an activator regenerated by electron transfer atom transfer radical polymerization mediated polymerization-induced self-assembly (ARGET ATRP PISA) process based on hydrogenated polyisoprene-b-poly (glycidyl methacrylate) (HPI-b-PGMA)/poly (glycidyl methacrylate) (PGMA) blends. The dynamic light scattering (DLS) and transmission electron microscopy (TEM) revealed effective control over a wide range of hydrodynamic diameters of stabilized spherical nano-objects. The thermogravimetric analysis (TGA) and microscale combustion calorimetry (MCC) demonstrated the efficient and controllable introduction of phosphoric acid (H₃PO₄) into nano-objects, with POs serving as the shell and flame retardants forming the core. This work was hoped to provide a versatile route to PO-based nano-objects and open a novel avenue for designing PO-based additives.

The inherent brittleness and flammability of epoxy resin (EP) significantly limit its applications in high-performance fields. To address these challenges, a P-functionalized diphenyl-methylvinyl-copolysiloxane additive (DOPS) was synthesized via a simple method using diphenylsilane, dimethoxymethylvinylsilane, and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). This additive was incorporated into epoxy systems cured with 4,4′-diaminodiphenylmethane (DDM), effectively enhancing both toughness and flame retardancy. When the DOPS content reached 6.93 wt%, the DOPS-4 thermosets achieved a V-0 rating in the UL-94 test. Additionally, the total heat release (THR) and total smoke production (TSP) of the DOPS-4 sample decreased by 41.34 % and 39.04 %, respectively, compared to the neat EP thermoset. These improvements were attributed to the trapping effect of P-containing radicals and the formation of a P/Si-containing char layer, which effectively inhibited combustion and reduced smoke and heat release. In addition, the flexural and impact strengths of DOPS-4 were improved by 15.6 % and 95.3 %, respectively, compared to the neat EP thermoset. These enhancements were ascribed to the rigid phosphaphenanthrene segments and abundant flexible chains in DOPS. Moreover, the DOPS-modified epoxy thermosets still exhibited excellent thermal stability. In sum, this work provides a facile and effective strategy to enhance the toughness and flame retardancy of epoxy thermosets, offering promising potential for advanced material applications.

New water-soluble coumarin-ketone-pyridium salts photoinitiators for antibacterial coatings under visible LED photocuring

IF 5.8 2区化学 Q1 POLYMER SCIENCE

With the increasing global emphasis on public health, personal hygiene, and environmental safety, the development of effective strategies to inhibit microbial growth and transmission has become a critical research focus, driving rapidly expanding demand for antibacterial materials across multiple fields. UV-photocured antibacterial coatings have gained widespread adoption due to their fast curing rates, low energy consumption, and environmentally friendly characteristics. However, commercially available water-soluble photoinitiators such as Irgacure 2959, while exhibiting certain photosensitivity and low cytotoxicity, demonstrate poor compatibility with visible LED light sources. Herein, we present a novel class of visible LED-sensitive coumarin-ketone-pyridinium salt photoinitiators with varied anions, systematically investigating their photoinitiation performance and antibacterial properties. Our findings reveal that these dual-functional photoinitiators in combination with coinitiator N-phenylglycine (NPG) enable efficient and rapid photocuring when exposed to visible LED irradiation, with the water-borne coatings demonstrating excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. Notably, both the photoinitiators and resultant coatings exhibit good hemocompatibility, underscoring their promising potential for antibacterial coating applications.
