MIL-53(Fe), as a typical metal–organic framework (MOFs) material, has shown broad application prospects in the field of membrane separation technology due to its advantages such as high specific surface area and good chemical stability. However, few studies have specifically applied it to the preparation of oil–water separation membranes. Therefore, this study innovatively proposed a self-assembly strategy. By constructing a MOFs composite coating covering the membrane surface and a comprehensive metal polyphenol network (MPN), this approach was designed to form an efficient, comprehensive oil-rejection system while significantly enhancing pure water flux. Then, through a series of characterizations and performance tests, the results showed that the prepared composite membrane exhibited excellent oil–water separation performance: pure water flux was as high as 3641.21 L m −2 h −1 , and at the same time, the rejection rate of oil-in-water emulsion was stably maintained at more than 99.58%. Therefore, this study not only successfully verified the great potential of MIL-53(Fe)-based composite membranes in the field of efficient oil–water separation, providing a new theoretical basis and feasible technical path for its design, but also further expanded the practical application prospects of MOFs materials in the treatment of oily wastewater, opening up new ideas for the development of the next generation of high-performance separation membranes.

Gels with excellent ionic conductivity and high-humidity resistance are highly desired in practical applications due to their potential to create wearable soft electronics that maintain reliable performance under humid conditions. Herein, we designed a fully hydrophobic eutectogel by one-step copolymerization of glycidyl methacrylate and 2-phenoxyethyl acrylate within a hydrophobic deep eutectic solvent (DES) composed of 1-allyl-3-methylimidazolium chloride and methyl 4-hydroxybenzoate. The optimized eutectogel exhibited exceptional moisture tolerance, featuring a water contact angle > 107° and humidity-insensitive ionic conductivity (0.10 mS·cm −1 at 90% RH). Subsequently, we fabricated a strain sensor that demonstrated stable resistance responses to multi-scale human motions, such as finger, wrist, and elbow joint bending, under both ambient and high-humidity conditions. This stability arose from the covalently crosslinked hydrophobic polymer network and non-hygroscopic DES, effectively mitigating water-induced sensing instability. The hydrophobic eutectogel sensor establishes a transformative platform for next-generation wearables in personalized healthcare and extreme-condition sensing.

To further enhance the comprehensive performance of polymer electrolytes, this study prepares a ternary composite gel polymer electrolyte (CGPE) based on TiO 2 /thermoplastic polyurethane (TPU)/polydimethylsiloxane (PDMS) via a solution casting method, systematically investigating the influence of TiO 2 content on the properties of CGPE. Structural characterization reveals that TiO 2 nanoparticles achieve a “dual crystalline phase regulation” mechanism by inhibiting polymer crystallization and introducing anatase crystal phase. When the TiO 2 content is 9 wt%, the CGPE exhibits optimal performance: ionic conductivity reaches 4.59 × 10 −3 S/cm, an 81.5% increase compared to the pure polymer matrix; tensile strength is 9.61 MPa, elongation at break is 449%; lithium ion transference number is 0.78; and the electrochemical stability window is 0–5.0 V versus Li/Li + . The assembled LiFePO 4 /Li half-cell demonstrates a rate capability of 87.4% when the current density increases from 0.1 to 1 C, with 99.2% retention after 100 cycles. The results confirm the application potential of TiO 2 -reinforced CGPE in high-safety lithium-ion batteries.

A novel triple-responsive composite hydrogel, p(NIPAM-co-MAA-co-SPMA), was designed and synthesized via free radical polymerization, incorporating N-isopropylacrylamide (NIPAM) for temperature responsiveness, methacrylic acid (MAA) for pH sensitivity, and spiropyran methacrylate (SPMA) for light responsiveness. This study aimed to develop a novel stimuli-responsive sustained release drug delivery system. The composition and structure of the hydrogel were characterized by nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Doxorubicin (DOX) was used as a model drug to evaluate loading and release behavior. The hydrogel achieved a drug loading content (DLC) of 25.7% and a drug loading efficiency (DLE) of 74.3% and enabled controlled release with approximately 89% cumulative DOX release within 6 h under combined thermal, acidic, and ultra-violet light stimuli. Cytotoxicity assays and cellular uptake studies confirmed the excellent biocompatibility of the hydrogel and its efficacy in suppressing cancer cell growth. These results highlight the potential of p(NIPAM-co-MAA-co-SPMA) as an intelligent platform for on-demand targeted anticancer therapy.

Plastic pollution poses a significant threat to the environment and human health, prompting the search for sustainable alternatives. Poly(butylene adipate-co-terephthalate) (PBAT), as a biodegradable material, offers a solution to replace polyolefin plastic. In this study, the effects of silane-modified potato waste (M-PW) content on the interfacial and physical properties of PBAT composites were investigated. Results indicate that increasing M-PW content deepens the color of the composites. FTIR analysis confirms successful grafting of the silane coupling agent γ-aminopropyl triethoxysilane (KH550) onto potato waste, with the composites forming a physical mixture of the two phases. M-PW exerts complex effects on mechanical properties: tensile strength first decreases and then increases, while impact strength declines continuously. Incorporating M-PW reduces the thermal stability of PBAT but enhances the composites' crystallization and melting properties, as well as their hydrophobicity. XRD analysis reveals that M-PW lowers the composites' crystallinity without altering the crystal structure of PBAT. SEM images demonstrate poor adhesion between high-load M-PW and the PBAT matrix. This study highlights the potential of agricultural waste in biodegradable plastics, but further research is required to improve M-PW dispersion and compatibility within the PBAT matrix, thereby enhancing mechanical performance.

The monovalent cation exchange membrane (MCEM) plays a crucial role in strategic resource recovery fields such as lithium/magnesium separation and seawater softening. This study proposes a two-stage modification strategy of “nanoparticle deposition – quaternization cross-linking”: first, deposit the Polypyrrole -Polyethyleneimine (PPY-PEI) composite nanoparticles in situ on the commercial Cation Exchange Membrane (CEM) surface, and then undergo quaternization cross-linking to prepare a high-performance monovalent cation exchange membrane (MCEM). The rigid structure of Polypyrrole -Polyethyleneimine (PPY-PEI) nanoparticles completely avoids the traditional problem of monomer penetration, and the rate of membrane pore blockage is significantly reduced. Electrified nanoparticles form gradient nanochannels to achieve dual mechanism synergy: The surface positive charge layer repels and blocks Mg 2+ through the Donnan effect; 2–5 nm mesoporous channels facilitate K + transport through size sieving. Subsequent quaternization crosslinking strengthened the modified layer and increased the positive membrane charge density, leading to further improvement in perm-selectivity. The results show that the modified membrane achieves a breakthrough performance in the separation of K + /Mg 2+ : the selectivity reaches 6.9; the K + flux remains at 0.14/(m 2 ·s). Molecular dynamic simulation of the ion diffusion behavior confirmed that the presence of Polypyrrole -Polyethyleneimine (PPY-PEI) can accelerate the diffusion rate of K + while limiting the transport of Mg 2+ , providing a theoretical basis for the performance prediction of selective ion exchange membranes.

Polyvinylidene fluoride (PVDF) and its copolymers have garnered significant interest for flexible and wearable sensors. However, the sensitivity of PVDF-based sensors is limited by their relatively low pyroelectric properties compared to those of inorganic ferroelectric materials. In this study, we report on poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) films exposed to x-ray irradiation to increase the crystallinity and β-phase content. This increase in crystallinity and β-phase content ultimately improved the pyroelectric coefficient (150.9 μC m −2 K −1 ) by almost more than five times. The sensors, based on the irradiated P(VDF-TrFE) films, showed an outstanding thermal voltage sensitivity of 15.07 V K −1 and a current sensitivity of 12.19 nA K −1 . The sensors exhibited excellent linear temperature sensing and a precision infrared detector, making them promising candidates for self-powered electronic skin in human-machine interaction applications.

In order to reduce the huge economic loss caused by clay hydration and swelling during drilling, it is very important to select shale inhibitors reasonably and efficiently. In recent years, ionic liquids have been active in various industries as a new material, among which 1-vinyl-3-ethylimidazole bromide salt has high temperature tolerance and certain inhibition ability. Therefore, in this paper, 1-vinyl-3-ethylimidazole bromide salt was used as a water-based drilling fluid inhibitor monomer, and the ionic polymer inhibitor (PIAA) were prepared by solution polymerization. The optimal synthesis conditions were determined by designing orthogonal experiments, and the properties of the materials were tested and evaluated. The experimental results show that PIAA is able to withstand temperatures up to 270°C. Compared with deionized water, the size of the mud ball after soaking in PIAA solution is smaller, and the linear expansion rate of bentonite in PIAA solution for 24 h is 29%. The shale recovery rate at 160°C was 86.5%, which was higher than that of deionized water (36.6%). When the base slurry is added, the zeta potential changes from negative to positive. XRD tests show that PIAA effectively compresses the bentonite bi-layer. After the addition of PIAA to the base pulp, the particle size of bentonite particles increased and the distribution was more concentrated. It also has good performance in the contact angle test and scanning electron microscope test, and at the same time will not damage the rheological properties of the base pulp and has a certain performance of reducing filtration loss.

The rising demand for polymers in engineering fields requires additional techniques to improve the toughness of inherently brittle plastics. Here, a strategy is proposed to toughen the brittle styrene–acrylonitrile copolymer (SAN) through dynamic vulcanization. Acrylonitrile-butadiene rubber (NBR) is introduced as a toughening agent, while dicumyl peroxide (DCP) is used as a curing agent to initiate dynamic vulcanization. The resulting SAN/NBR TPVs exhibit a co-continuous structure, different from the traditional “sea-island” structure of classical TPVs. The continuous NBR network functions as a pathway for stress transfer, playing a key role in toughening SAN. Significant plastic deformation and stretched microfibrils with high orientation form along the impact direction, absorbing energy and enhancing toughness. With 40 phr NBR, the SAN/NBR TPVs achieve an impact strength of 53.5 kJ/m 2 and a tensile toughness of 18.4 MJ/m 3 , which are 29.7 and 12.2 times higher than those of the neat SAN, respectively. Meanwhile, the tensile strength of the TPVs remains nearly the same as that of the simple blend.

Leather retanning agents are of great meaning for the reactive competence and thermal, physical, and mechanical properties of treated leather fibers. For this motif, reactive amphoteric polyurethane with multialdehyde groups (AAPU) was prepared by a polyaddition reaction with isophorone diisocyanate, poly(tetrahydrofuran glycol), 2,4-dihydroxybenzaldehyde, 2,2-dihydroxymethyl propionic acid, and N -methyl diethanolamine as raw materials and was then used as a retanning agent to explore its effects on leather fibers. The structure of AAPU was confirmed by UV, Fourier transform infrared, and 1 H-NMR spectroscopy. An average particle size of 42.6 nm and an isoelectric point of 5.16 were determined. The thermal stability, physical and mechanical properties, and morphology of the AAPU-treated leather fibers and their reactivities to anionic materials were investigated. Because of the crosslinking effect of multisite covalent bonds, which resulted from reactions between the aldehyde groups in AAPU and the pendant amido groups from collagen fibers, and the role of the cationic groups in AAPU, the thermal stability of the treated leather fibers and their reactivity to anionic materials, such as dyestuffs and fatliquoring agents, were enhanced. Thus, the absorption rate of dyes was almost as high as 99.89%, and the physical and mechanical properties of the AAPU-treated final leather fibers were superior to those of the contrast. © 2019 Wiley Periodicals, Inc.

A novel erythrosine B derivative linked with a tertiary amine used as a visible light initiator for free radical polymerization was synthesized and characterized. For comparison, the free hydrophobic erythrosine B derivative was also synthesized and its combination with the tertiary amine was used as the separated two component photoinitiator. The linked initiator exhibited higher photoinitiator efficiency in high viscosity monomer than in low viscosity one, compared with the separated counterpart. Especially, when it was combined with iodonium salt, the further promotion of the photoinitiator efficiency was observed, compared with the separated three component system. It was found that as iodonium salt together with tertiary amine was continuously added to the formula with the linked initiator, the photoinitiator efficiency was dramatically enhanced compared with the same addition to the formula with the separated counterpart, revealing the application potential of the linked initiator. And the continuous addition of either the iodium salt or the tertiary amine to the formula only leaded to the small size increase of the photoinitiator efficiency. These results suggested that there existed an interdependent relationship between iodonium salt and tertiary amine in promoting the photoinitiator efficiency of the dye/amine/iodonium salt system. For these, the corresponding synergistic mechanism was proposed. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 42361.

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
