Deltamethrin (DM) is one of the most efficient pyrethroid insecticides, which is widely applied to the control of insect pests in tea. In this work, efficient molecularly imprinted polymers (MIPs) were synthesized using DM as the template and acrylamide as the functional monomer, in conjunction with two-step seed swelling polymerization. Scanning electron microscopy, Fourier transform infrared spectroscopy, and Brunauer–Emmett–Teller surface area analysis confirmed the staggered pore structure and the presence of binding site in DM MIPs. The adsorption properties of the DM MIPs were also investigated based on assessing equilibrium adsorption as well as kinetic modeling and solid-phase extraction. Isothermal equilibrium adsorption experiments show that the adsorption behavior is consistent with the Freundlich and Halsey models, indicating heterogeneous multilayer specific adsorption. Fitting of the kinetic data demonstrates that chemical adsorption could be the rate-limiting step in DM extraction, which is consistent with a pseudo-second-order kinetic model. Using the imprinted polymers as solid-phase extraction filler, the DM recoveries from various teas were greater than 80% and exceeded those of the structural analogs cypermethrin, lambda-cyhalothrin, and bifenthrin. These results confirm that the MIPs exhibit specific adsorption of this analyte. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 47415.

Self-lubricating composite with stimuli-responsive properties attracts great interest in recent years. Herein, mesoporous silica (MS) as oil-laden containers is explored to achieve self-lubricating feature. The as-prepared MS possesses a high Brunauer-Emmett-Teller (BET) surface area (1,542.35 m 2 /g), which satisfies the criterion for construction of ideal repository for storing enough liquid lubricants. In addition, the thermal stimuli-responsiveness behavior of the oil-laden mesoporous silica (OMS) for lubrication has been investigated by thermogravimetric analyzer tester. As expected, an excellent tribological performance (friction coefficient and wear rate decreased by 63.29 and 82.63%) is obtained by adding 10 wt% OMS into the polyurathene matrix, showing great promise for self-lubricating application.

An ionic liquid (IL)-based monolithic poly(ionic liquid glycidylmethacrylate- co -ethylene glycol dimethacrylate) column was prepared via in situ free-radical polymerization with 1-vinyl-3-butylimidazolium chlorine as one of the comonomers. The obtained monolithic column was used as the sorbent of solid-phase extraction (SPE) and coupled with high-performance liquid chromatography for the simultaneous determination of the macrolide antibiotics roxithromycin (ROX) and acetylspiramycin (ACE) in processed pure milk. The monolithic column was characterized by Fourier transform infrared spectrometry, scanning electron microscopy, nitrogen absorption–desorption, mercury intrusion porosimetry, and thermogravimetric analysis. The results reveal that the monolithic column exhibited a high selectivity and good permeability to the macrolide antibiotics in milk. The optimized method offered excellent linearity with a linear regression coefficient greater than 0.998. The precisions for interday and intraday were both less than 7.7%. The accuracies expressed by the recoveries for ROX and ACE were in the ranges 92.5–103.8 and 93.0–107.6%, respectively. Compared to the previous methods, this method had a low limit of detection and a good accuracy. As a result, the polymer IL based monolithic column could feasibly be used as a high-selectivity online SPE sorbent for determining trace macrolide antibiotics in milk. © 2016 Wiley Periodicals, Inc.

A series of macroporous beaded terpolymers with epoxy groups were synthesized by suspension polymerization with glycidyl methacrylate (GMA), ethylene glycol dimethacrylate (EGDMA), and the third monomers including styrene, methyl methacrylate, n -butyl acrylate (BA), butyl methacrylate (BMA), and 2-hydroxyethyl methacrylate for immobilization of Candida lipolytica lipase. The effect of various third monomers on loading and activity recovery of immobilized lipase were studied. Terpolymers with BA as the third monomer were found to give the biggest loading of lipase, and the activity recovery of lipase immobilized on poly(GMA-EGDMA-BA) terpolymers reached 79.0%. As the content of BA (%) increasing, the loading of lipase enhanced, but the activity recovery reached 88.5% for the initial stage and decreased to 46.9% at last. The poly(GMA-EGDMA-BA-10) showed an optimal result in lipase immobilization. Lipase immobilized on poly(GMA-EGDMA-BA-10) carriers had broader pH and higher temperature stability. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Developing intelligent antibacterial materials with environmental responsiveness is crucial for addressing the challenges of real-time monitoring and efficient infection control in the fields of wound healing and environmental remediation. In this study, a multifunctional Janus electrospun nanofibrous membrane based on a synergistic system of anthocyanin/thymol (AN/THY) was developed, which integrated unidirectional water transport, pH-responsive monitoring, antibacterial and antioxidant properties. Experimental results demonstrate that the Janus nanofibrous membrane exhibits excellent unidirectional water transport and inhibits reverse penetration due to the gradient pore structure and wettability difference between layers. It also exhibits a suitable physiological environment-compatible gas permeability of 14 mm/s, enabling efficient gas exchange. In addition, the bilayer membrane shows a DPPH radical scavenging rate of up to 91% and an antibacterial rate of nearly 100% against Escherichia coli and Staphylococcus aureus ; moreover, the membrane exhibits distinct color changes within the pH range of 3–13 and a high color reversibility of more than 95%. The developed Janus nanofibrous membrane has great potential in the fields of intelligent wound dressings, environmental monitoring, and provides a new strategy for the development of multifunctional intelligent materials.

Radiation protection products (RPP) that provide thermal insulation and radiation safety are crucial for personnel exposed to nuclear materials. Unfortunately, existing RPPs are unable to withstand the demands of high-temperature working environments, which severely limits their applications. In this work, flower-shaped Bi 2 O 3 (FBi 2 O 3 ) filled waterborne polyurethane (WPU) foam is proposed to address this challenge. The filling volume of this foam is relatively low, which makes it lightweight. Meanwhile, the compatibility of the interface between FBi 2 O 3 and WPU is improved by modifying the surface of the FBi 2 O 3 using titanate coupling agent (TCA). The uniform dispersion of FBi 2 O 3 enables the material to exhibit excellent x-ray shielding properties (94%–99%) and low thermal conductivity (0.033 W/(m K)). Experimental and simulation results indicate that the interaction between materials and x-rays increases collision probability and reduces secondary scattering. This study provides a viable approach for fabricating lightweight, thermally insulating RPP, opening new avenues for developing advanced RPP.

As a widely used general-purpose plastic, polyvinyl chloride (PVC) suffers from limited thermal stability, inherent brittleness, and a difficulty in balancing mechanical strength with toughness. To overcome these limitations, aramid nanomaterials (ANM)—formed through the self-assembly of poly(terephthaloylterephthalamide) (PPTA) molecules as the reinforcing phase—are directly constructed via an in situ synthesis (ISS) strategy in PVC/NMP and PVC/NMP/LiCl systems. Results demonstrate that this method achieves uniform dispersion and strong interfacial bonding of ANMs within the PVC matrix, significantly refining the composite microstructure. Compared with neat PVC, the PVC/ANM composites prepared by the ISS method showed a significant increase in both tensile strength and toughness, effectively breaking the conventional strength–toughness trade-off. In addition, these composites show enhanced thermal stability and flame retardancy, primarily due to strong interfacial interactions between the ANMs and the PVC matrix. This work not only confirms the great potential of the ISS strategy for preparing high-performance PVC composites but also provides a new technological pathway for addressing common strengthening and toughening challenges in polymer-matrix systems.

The accumulation of plastic waste in marine environments poses a significant ecological threat, highlighting the urgent need for intrinsically hydro-degradable polymers. Poly(butylene oxalate) (PBO) hydrolyzes rapidly but its degradation rate is too fast for practical applications. To address this challenge, rigid cyclohexanedimethanol (CHDM) units were introduced into the PBO backbone to synthesize a series of poly(butylene cyclohexanedimethylene oxalate) (PBCO) copolyesters with CHDM content ranging from 19.3 to 75.3 mol%. Their chemical structure, crystallization behavior, thermal and mechanical properties, rheology, and degradation profile were systematically investigated. Results indicated that CHDM incorporation significantly affects properties: crystallinity, melting point, and mechanical strength exhibit a V-shaped trend with increasing CHDM content, whereas thermal stability, glass transition temperature, and melt viscosity increase monotonically. Notably, the seawater degradation rate displays a unique non-monotonic trend, initially accelerating and then substantially slowing as CHDM content increases. The decomposition temperature decreased by 58.8°C, elongation at break increased by 64%, and degradation rate reduced, collectively extending the material's applicable window. This work demonstrates a viable strategy for finely tuning the degradation profile, thermal and mechanical properties of aliphatic polyesters via rigid-unit copolymerization, offering a promising material solution that balances service life and hydrolytic degradability for specific applications.

Polydimethylsiloxane (PDMS) sponges exhibit low oil adsorption capacity due to their monolithic pore structure and limited surface area. Here, we present SDS-ZIF-67/PDMS composite sponges that overcome these limitations. ZIF-67 particles are incorporated into the PDMS matrix via a soft-templating approach, creating a submicron hierarchical pore structure and increasing the number of accessible adsorption sites. Surface functionalization with sodium dodecyl sulfate (SDS) introduces long alkyl chains, modulating surface chemistry and enhancing selective affinity for oil molecules. The composite sponge exhibits a water contact angle of 135°, reaches adsorption equilibrium within 6 min, and achieves 96% separation efficiency for various oils and oil–water mixtures. After 15 adsorption–desorption cycles, 87% of the initial adsorption capacity is retained, demonstrating exceptional cyclic stability. These findings underscore the potential of SDS-ZIF-67/PDMS composite sponges for efficient treatment of oily wastewater.

Antibacterial poly[(acryloyloxyethyl trimethyl ammonium chloride)-co-(hydroxyethyl methacrylate)-co-(methyl methacrylate)] (P(DAC-HEMA-MMA)) was designed and synthesized via aqueous copolymerization using DAC, HEMA, and MMA as cationic, functional, and hydrophobic monomer, respectively. The structure, thermal property and elemental composition of the copolymer were characterized by multiple techniques. Antibacterial performance test showed that minimum inhibitory concentrations (MIC) of P(DAC-HEMA-MMA) against both Escherichia coli and Staphylococcus aureus were 3.12 mg/mL. When P(DAC-HEMA-MMA) was applied to the aged paper sample, its tensile strength, folding endurance, and tearing resistance were increased by 88.4%, 118.7%, and 60.5%, respectively, with a whiteness improvement of 21.5%. After dry-heat aging, it still remained excellent anti-aging ability. In addition, the antibacterial rates of the treated paper sample against E. coli and S. aureus reached 69.2% and 97.7%, respectively, and the treated one maintains unchangeable antibacterial performance after exposing to the ambient condition for 3 months; the water contact angle reached 118.9°, higher than that of the original paper sample, and however, it was decreased over time. All the results confirmed P(DAC-HEMA-MMA) treatment can effectively enhance the mechanical properties of the paper samples, and endow them with wonderful antibacterial and hydrophobic properties, thus holding multifunctional application in the field of paper postprocessing.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a representative bio-based biodegradable polyester; however, its high crystallinity and brittleness severely restrict its practical applications. To improve its mechanical performance, a thermoplastic copolyester (TPC) elastomer (ET) was used as a toughening agent, and a reactive interfacial compatibilizer—poly(glycidyl methacrylate) (PGMA)—was synthesized to enhance interfacial adhesion between PHBV and the TPC-ET, improving their compatibility. Differential scanning calorimetry and Fourier transform infrared spectroscopy analyses indicated that the epoxy groups of PGMA formed hydrogen bonds with the PHBV and TPC-ET phases, strengthening intermolecular interactions and restricting blend crystallization. Rheological and scanning electron microscopy results revealed that the incorporation of PGMA improved the interfacial bonding, refined the dispersed-phase size, and produced a uniform sea–island morphology. Consequently, the mechanical properties of the PHBV/TPC-ET/PGMA blends considerably improved: the impact strength reached 17.58 kJ m −2 , elongation at break reached 8.23%, and tensile strength reached 27.5 MPa—representing improvements of 270.1%, 69%, and 190.4%, respectively, compared with those of pristine PHBV. The proposed strategy effectively toughens PHBV and increases its application potential in sustainable polymer materials.

A reactive flame-retardant acrylate monomer (PEDP) with a high phosphorus content has been synthesized through a straightforward process to improve the fire safety of UV-curable materials. In comparison to the traditional monomer PETA, the UV-cured PEDP (UV-PEDP) enhances the limiting oxygen index (LOI) from 28.7% to 31.9% and achieves a UL-94 V0 rating without any melt dripping. Meanwhile, UV-PEDP exhibits a 42.7% reduction in peak heat release rate (PHRR) and a 30.6% decrease in total heat release (THR) compared to UV-PETA in the cone calorimetry test (CCT). Mechanistic analysis attributes the improved flame retardancy to gas-phase quenching and dilution effects from phosphorus-containing decomposition products, as well as the formation of char in the condensed phase. The UV-PEDP demonstrates high transparency (exceeding 80% at 800 nm) and excellent hardness (above 93 Shore-D). Although there is a decrease of 27% in tensile strength and 30% in elongation, these trade-offs remain acceptable for many coating applications. This study presents an effective strategy to expand the safe use of UV-curable materials.
