In this paper, a modified sericin containing active acryloyl groups (MSAA) was prepared by amidation reaction using acryloyl chloride and sericin as raw materials, and its structure was analyzed by FT-IR, fluorescence spectrum, zeta potential and 1 H NMR. The results showed that the active acrylyl groups were successfully introduced into the molecular chains of sericin. Then, MSAA and an alkaline crosslinking agent 1,3,5-triacroylaminohexahydro-s-triazine (FAP) were combined to finish cotton fabric in alkaline condition. Under alkaline condition, the anti-wrinkle effect of cotton fabric could be improved by finishing with MSAA and FAP. By measuring the wrinkle recovery angle, it was found that with the increase of MSAA content, the anti-wrinkle effect of cotton fabric was obviousy improved, without significant impact on the strength and whiteness of the fabric. In addition, the dyeing property and ultraviolet resistance of the finished fabric could be apparently improved.

The quality of yogurt deteriorates during storage due to exposure to oxygen and UV light, and high-barrier packaging effectively mitigates this issue. Concurrently, there is increasing interest in replacing petroleum-based packaging with eco-friendly alternatives. In this study, poly(lactic acid-butylene itaconate) (PLBI), developed as a modified version of poly (L-lactic acid) (PLLA) to enhance toughness, was combined with poly (vinyl alcohol) grafted with acryloyl chloride (PVA-g-AC) through UV curing. The resulting PLBI/PVA-g-AC films exhibited significantly improved barrier properties. They were used to package stirred yogurt alongside polyethylene/nylon (PE/NY) films for comparison. Quality assessments, including acidity, water-holding capacity, and viable bacterial counts, demonstrated that PLBI/PVA-g-AC films provided superior preservation. Metabolomics analysis revealed increased flavor compounds, such as acids and alcohols, and decreased sugar levels in these packaged yogurt. This work expands potential applications of PLLA-based materials in food packaging and offers insights into the influence of oxygen on yogurt storage quality.

A novel and convenient synthetic method for the preparation of α,ω-bis(2,6-dimethylphenol)-poly(2,6-dimethyl-1,4-phenylene oxide) (PPO-2OH) oligomer in water is presented. It is based on the oxidative copolymerization of 2,6-dimethylphenol (DMP) and aromatic diols in the presence of Cu-ethylene diamine tetraacetic acid catalyst in water. It was found that the mole fraction of PPO-2OH in the product was affected by species of aromatic diols and mole ratio of DMP to aromatic diols. Species and concentration of surfactants were demonstrated to be significant factors that would influence molecular weight (Mn) and yield of PPO-2OH. The synthesized PPO-2OH was end-group modified with methacryloylchloride (MAC) to obtain dimethacryloyl chloride telechelic PPO (PPO-2MAC). The relationship between glass transition temperature (Tg) and Mn of PPO-2OH is in good agreement with the Flory–Fox equation. Thermal polymerized low-molecular-weight PPO-2MAC has a constant Tg at about 208 °C.

There are two major problems associated with the use of antibacterial cotton fabric. The durability of the fabric is poor, and the inherent properties of the fabric deteriorate following the execution of the finishing processes. These limit the application of antibacterial fabric. We first treated the cotton fabric with acryloyl chloride (AC) molecules to make the surface of the fabric rich in carbon‑carbon double (C=C) bonds. Following this, the [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMES) monomer was polymerized with the C C bonds on the fabric following the “grafting through” method. As a result, the cotton fabric was successfully grafted with the poly[2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (PDMES), exploiting covalent bonds . The finished fabric exhibited excellent antibacterial effects. The bacterial reduction (BR) rates of the finished fabric against E. coli and S. aureus were greater than 99.0 %. Even after 50 washing cycles, the BR rates of the finished fabric against E. coli and S. aureus were greater than 96.0 %. In addition, the use of the “self-created” mist polymerization technology ensured that the inherent properties of the finished fabric were retained to a large extent. Therefore, the antibacterial cotton fabric prepared following this method can be potentially used for the fabrication of industrial and household textiles.

The rapid development of 3D printing technology and the emerging applications of shape memory elastomer have greatly stimulated the research of photocurable polymers. In this work, glycerol (Gly) was polycondensed with sebacic, dodecanedioic, or tetradecanedioic acids to provide precursor polyesters with hydroxyl or carboxyl terminal groups, which were further chemically functionalized by acryloyl chloride to introduce sufficient, photocurable, and unsaturated double bonds. The chemical structures of the acrylated polyesters were characterized by FT IR and NMR spectroscopies. The photoinitiated crosslinking behavior of the acrylated polyesters under ultraviolet irradiation without the addition of any photoinitiator was investigated. The results showed that the precursor polyesters that had a greater number of terminated hydroxyls and a less branched structure obtained a relatively high acetylation degree. A longer chain of aliphatic dicarboxylic acids (ADCAs) and higher ADCA proportion lead to a relatively lower photopolymerization rate of acrylated polyesters. However, the photocured elastomers with a higher ADCA proportion or longer-chain ADCAs resulted in better mechanical properties and a lower degradation rate. The glass transition temperature (Tg) of the elastomer increased with the alkyl chain length of the ADCAs, and a higher Gly proportion resulted in a lowerTgof the elastomer due to its higher crosslinking density. Thermal gravimetric analysis (TGA) showed that the chain length of the ADCAs and the molar ratio of Gly to ADCAs had less of an effect on the thermal stability of the elastomer. As the physicochemical properties can be adjusted by choosing the alkyl chain length of the ADCAs, as well as changing the ratio of Gly:ADCA, the photocurable polyesters are expected to be applied in multiple fields.

In this study, novel monodisperse restricted access media-molecularly imprinted polymers were successfully prepared by surface initiated reversible addition-fragmentation chain transfer polymerization using monodisperse crosslinked poly (glycidyl methacrylate-co-ethylene glycol dimethacrylate) microspheres as the carrier and acryloyl chloride-modified β-cyclodextrin as the hydrophilic functional monomer. The surface morphology, protein exclusion, and adsorption properties of the molecularly imprinted polymers were investigated. The results show that the material has excellent monodispersity and hydrophilicity, and simultaneously exhibit high adsorption capacity, fast binding kinetics, high selectivity, and significant thermal stability. The molecularly imprinted polymers as dispersive solid-phase extraction adsorbent combined with reversed-phase high-performance liquid chromatography was used to selectively enrich, separate, and analyze trace 17β-estradiol in milk samples. The recovery of 17β-estradiol is 88–95% with relative standard deviation of <4%, and the limits of detection and quantification of this method are 2.08 and 9.29 µg/L, respectively. The novel restricted access media-molecularly imprinted polymer adsorbents provide an effective method for the selective extraction and detection of 17β-estradiol directly from complex samples.

To overcome the constraints posed by traditional acrylamide-based polymers in harsh reservoir environments, this study synthesized a novel Gemini-type hydrophobically associating polymer (PAAD) via micellar copolymerization, incorporating acrylamide, 2-acrylamido-2-methylpropanesulfonic acid, and a meticulously designed Gemini surfactant monomer. A comprehensive evaluation was conducted on PAAD’s solution behavior, resistance to temperature and salt, shear stability, and enhanced oil recovery performance, with a comparative analysis to partially hydrolyzed polyacrylamide (HPAM), which is currently utilized in oilfields. The experimental results revealed that the critical association concentration of the Gemini-type hydrophobically associating polymer fell within the range of 1.5 to 2.0 g/L. Under identical concentration conditions, PAAD demonstrated superior thermal stability, salt tolerance, and shear resistance when compared to HPAM, while effectively reducing the oil–water interfacial tension to 0.3 mN/m. This study provides both theoretical basis and technical support for the practical application of hydrophobically associating polymers in high-temperature, high-salinity reservoirs.

Thrombus formation associated with blood-contacting catheters remains a prevalent clinical issue. Antithrombotic coatings capable of inhibiting coagulation activation without interfering with hemostasis are highly desired. Herein, we constructed thick and densely packed poly(ε-acryloyl l-lysine) (p(LysAA)) zwitterionic brushes on the inner wall of chemical inert polyethylene (PE) catheters via a recently developed universal, substrate-independent coating strategy that enables facile scaling-up for catheters with complex geometries. The densely packed l-lysine-derived zwitterionic brushes exhibited ultrahydrophilic properties, with water contact angles below 10°. As expected, fouling by bovine serum albumin, fibrinogen, bacteria, platelets, and red blood cells was effectively suppressed. Moreover, the brushes demonstrated excellent biocompatibility, as evidenced by relative cell growth rates of over 90%, a hemolysis rate of below 1%, and intradermal reaction scores of less than 1.0. Importantly, it showed antithrombotic efficacy both in vitro and an in vivo. In a rabbit arterio-jugular vein shunt model, no obvious clotting was observed after 1 h of circulation. Overall, the brushes hold significant clinical potential in reducing the level of thrombus formation for blood-contacting catheters. Furthermore, by leveraging the abundant reactive amine and carboxyl groups within the p(LysAA) brushes, this approach provides a platform for integrating bioactive molecules to further mitigate the thrombotic risk.

A strategy in which shape-memorable imprint cavities are constructed using peptide crosslinker (PC) was recently developed and the two major challenges for protein-imprinted polymers, i.e, difficult template removal and low imprinting efficiency, were successfully overcome.. Unfortunately, these polymers fail to bind the target protein at physiological pH, which severely limits their applications. Herein a novel PC based on the copolymer of γ-(2-(2-(2-methoxyethoxy)ethoxy)ethyl L-glutamate (EG 3 Glu) and L-boronophenylalanine (BPA) was designed and synthesized. The PC adopts an α-helical conformation at physiological pH but converts to extended coil conformation at high pH values. Using it as crosslinker, BSA-imprinted polymer was synthesized. Because of the reversible and precise pH-induced helix-coil transition of the peptide segments, the template can be removed facilely by elution with pH 11.5 solution. Meanwhile high affinity towards the template protein BSA is achieved at physiological pH. Both imprinting factor (6.28) and adsorption capacity (965.57 mg/g) is significantly higher than the polymer crosslinked with the common crosslinker N,N’-methylenebisacrylamide (BIS). The polymer also demonstrates high selectivity towards BSA and excellent reusability.It was successfully used to remove BSA from mixed solution of BSA and lysozyme at physiological pH. Not only BSA was removed selectively and efficiently, but the bioactivity of lysozyme was not affected, because BSA removal was performed under very mild conditions, i.e., at physiological pH and room temperature.

Conductive organohydrogels based on MXene have shown great potential in the domain of wearable healthcare applications. Nevertheless, traditional hydrogels encounter significant challenges related to instability and inadequate adhesion, which hinder the development of hydrogels for the long-term and reliable recording of weak electrophysiological signals. Thus, in this study, we introduced a novel conductive organohydrogel composite by integrating tannic acid (TA)-modified MXene (MXene@TA) into polyacrylamide (PAM) and sodium carboxymethylcellulose (CMCNa) networks. MXene@TA significantly enhanced its stability and the incorporation of glycerol into the system led to the organohydrogel's remarkable water retention and anti-freezing properties. The results demonstrated that the organohydrogels exhibited high elongation at break (1800 %), excellent toughness (275 kJ m −3 ), self-adhesion, frost resistance, and long-term water retention. The high sensitivity (GFmax = 15.6) of this organohydrogel composite over a wide strain range (0–1000 %) allowed for the detection of a wide range of body movements and the high degree of adherence conformity and the exceptionally low interfacial impedance allowed for the accurate long-term monitoring of subtle electrophysiological signals, such as electromyography and electrocardiography, among others. This study proposed a comprehensive methodology for the development of long-term stable MXene-based organohydrogels as a class of flexible electronic devices.

Matrix viscoelasticity as the typical mechanical feature of the extracellular matrix (ECM) of living tissues has been recently identified to impose profound impact on cellular behavior and functionalities. However, their effect on macrophages and the related inflammatory responses have been rarely explored, in which a major hurdle is the lack of candidate ECM-mimicking biomaterials with independently fine-tunable viscoelasticity. Herein, we developed a class of photopolymerizable hydrogels based on hierarchical hydrogen bond (H-bond) design to enable controllable stress relaxation behavior. Specifically, acrylamide (AM) and N-acryloyl glycinamide (NAGA) monomers were polymerized to form hydrogel networks consisting of varying ratio of single H-bond by AM and dual H-bond by NAGA, thus hydrogels with tunable stress relaxation rate but constant matrix elasticity can be developed via mediating monomer mixing ratios and polymerization degree. We further revealed that slower stress relaxation induced macrophage towards pro-inflammatory M1 polarization, while faster stress relaxation stimulated macrophage to polarize towards anti-inflammatory M2 phenotype. In vivo subcutaneous implantation of different hydrogel matrices using a mice model showed similar impact on host immune responses, as evidenced by severer inflammation characterized by thicker fibrosis encapsulation for matrix with slower stress relaxation than the faster ones. In general, we demonstrate that matrix viscoelasticity can significantly affect macrophage-mediated inflammatory responses, which provides new insights for the design and applications of implantable biomaterials. Statement of Significance This work revealed how extracellular matrix viscoelasticity characterized by stress relaxation rate can significantly impact macrophage polarization and inflammatory responses, which has rarely been explored previously. We proposed an innovative and ease-of-preparation class of copolymer hydrogels based on tailoring the mixing ratio of acrylamide (AM) and N-acryloyl glycinamide (NAGA) monomers, wherein matrix with fine-tunable stress relaxation rates can be achieved via controlling the combination of singular or dual hydrogen bonds. We further demonstrated that slower stress relaxation induced macrophage towards pro-inflammatory M1 polarization, while faster stress relaxation stimulated macrophage to polarize towards anti-inflammatory M2 phenotype. Our study suggests matrix viscoelasticity can significantly affect macrophage-mediated inflammatory responses, and provides new insights for the design and applications of implantable biomaterials.

Slide-ring hydrogels (SR-Gel) feature mechano-adaptive networks with exceptional stretchability and skin-adaptability, ideal for smart dressing applications. However, current SR-Gel systems primarily rely on polyrotaxanes fabricated from poly(ethylene glycol) (PEG) and α-cyclodextrins (α-CDs), which typically possess an uncontrollable host-guest coverage ratio. It is therefore crucial to develop efficient construction strategies that enable the fabrication of diverse SR-Gels and broaden their scope and utility. Herein, we designed a polymerizable pseudo polyrotaxane with low host-guest coverage via precise molecular recognition between β-cyclodextrin (β-CD) and a bile-acid-derived guest polymer. This precursor was photopolymerized with zwitterionic sulfobetaine methacrylate and N - acryloyl glycinamide to construct a skin-adaptable SR-Gel. The sliding crosslinks provide enhanced chain mobility, endowing the hydrogel with high stretchability, excellent fatigue resistance, and the ability to adapt to wound deformation. Furthermore, levofloxacin-loaded ZIF-8 nanoparticles (ZIF-8@Levo) were incorporated to obtain a conductive composite hydrogel (SR-Gel/ZL), which was not only applied to treat bacterial infections, but could also stimulate and differentiate temperature, blood, and pressure, simultaneously. This work represents the first SR-Gel system constructed from a bile acid/β-CD polyrotaxane. Compared with the traditional PEG/α-CD system, the host-guest ratio can be precisely controlled, and the synthesis steps are simpler, providing a universal molecular model for the development of high-performance slide-ring materials.
