The frequent occurrences of offshore oil spills have led to severe environmental contamination and ecological threats. However, traditional recovery methods pose issues such as high-energy consumption, low absorption efficiency and secondary pollution. This work prepared a hydrophobic aerogel (P-GO@CNTs-9/ATP/SA) using sodium alginate, attapulgite and graphene oxide surface-modified carbon nanotubes with superior solar/Joule heating ability. The water contact angle of this aerogel is approximately 147.5°. Moreover, this aerogel demonstrates stable and efficient photothermal conversion properties, reaching a surface temperature of 82.3 °C under one solar illumination (1 kW/m 2 ). Furthermore, when applying a voltage of 10 V, the surface temperature of the P-GO@CNTs-9/ATP/SA aerogel reaches 170.4 °C, assisting photothermal conversion to enhance the fluidity of viscous oil, thereby conserving energy. Finally, we present a continuous absorption device utilizing P-GO@CNTs-9/ATP/SA as the primary component, enabling automatic switching between photothermal and electrothermal modes for the comprehensive and continuous treatment of oil spills. Due to the unique design, environmental friendliness and ideal absorption capacity, this approach offers a novel choice for recovery of oil spills, which is expected to further promote principles of sustainable development.

The porous thermosensitive imprinted polymer of MW-Ru(IV)-TIIP was prepared in a short time with the aid of a microwave. The structure and morphology of MW-Ru(IV)-TIIP were characterized by ATR-FTIR, SEM-EDS, and BET. The thermosensitive block PDEA- b -P(DEA- co -AM) was introduced into the imprinted polymer preparation system. N-MAM and AA were selected as functional monomers, and stable HIPE Pickering emulsions were prepared under high-speed stirring, combined with multi-field coupling technology. The synthesis process of MW-Ru(IV)-TIIP was studied, and the dosages of template ion, functional monomer, and cross-linking agent, as well as microwave power, polymerization temperature, and polymerization time, were optimized. Under optimal technological conditions, the maximum adsorption capacity of MW-Ru(IV)-TIIP reached 0.20 mmol L −1 at 33°C, and adsorption equilibrium was reached within 240 min. Theoretical studies showed that the adsorption of MW-Ru(IV)-TIIP conformed to the quasi-first-order kinetic model and the Langmuir model. When MW-Ru(IV)-TIIP was applied to a diluted platinum group catalyst leaching solution, its adsorption capacity for MW-Ru(IV)-TIIP to Ru was 0.23 mmol L −1 , and the purity of platinum group metals increased from 53.72% to 76.43% after one adsorption/desorption cycle. After 11 reuses, the adsorption capacity maintained 70.06% of the original capacity, indicating that MW-Ru(IV)-TIIP had good potential in industrial applications.

In dealing with the oil–water separation process, improving the oil–water selectivity of the membrane surface and increasing the porosity within the membrane are effective means to achieve durable and efficient oil–water separation. Therefore, polystyrene/polyacrylonitrile-polyvinylidene fluoride/Polydimethylsiloxane Fe 3 O 4 nanoparticles (PS/PAN-PVDF/PDMS@Fe 3 O 4 ) composite membranes with superhydrophobicity and lipophilicity were prepared by electrospinning technique. By controlling the filling concentration of Fe 3 O 4 nanoparticles, a stable superhydrophobic and lipophilic rough structure was constructed, and micro–nano multilayer rough voids existed inside the membrane. The results showed that the composite fiber membrane exhibited exceptional superhydrophobicity (156.2°), thermal stability (338°C), mechanical properties (tensile strength of 3.0 MPa, elongation of 33.9%), and oil adsorption capacity (30–100 g/g). Moreover, even under corrosive environments, this composite fiber membrane maintained its superhydrophobic properties (above 152°) and achieved high oil–water separation efficiency (above 97%). Remarkably, after 40 cycles, the composite membrane could sustain a separation flux of 5000 L m −2 h −1 . Consequently, the composite fiber membrane manufactured using this strategy exhibits promising potential for applications in oil–water separation.

Covalent adaptable networks offer a viable approach for producing recyclable rubber materials. Nevertheless, the intricate synthesis process and insufficient mechanical strength limit their commercialization applications. In this study, the reinforced, thermal-healing, and recyclable chitosan/ethylene propylene diene rubber (CEF-CS) was synthesized using a solid-phase blending process via the Diels-Alder (D-A) reaction. Furfural modified chitosan (F-CS) was included as a reinforcing filler and dynamic cross-linking point into the network formed via the D-A reaction. The influence of F-CS content on the mechanical, thermomechanical, and thermal repair characteristics of CEF-CS composites was examined. The results showed that the CEF-CS composites exhibited certain mechanical strength and dependable repair capabilities. As the F-CS content increased, the tensile strength of CEF-CS composites initially rose and subsequently declined, reaching a peak of 5.1 MPa, which was 5.1 times more than the control without F-CS. The first healing efficiency of tensile strength exceeded 70%, whereas the second healing efficiency was above 60%. Moreover, the simple preparation procedure and enhanced mechanical strength facilitate the commercial utilization of recyclable rubber materials, which is crucial for addressing the environmental pollution issue associated with rubber materials.

This work aims to develop a new conductive hydrogel using sodium carboxymethyl cellulose (Na + CMC), acrylic acid (AAc), and N , N -dimethylaminoethyl methacrylate (DMAEMA), with antibacterial properties. The hydrogel was prepared through free radical polymerization, with the adjustment of Na + CMC concentration to enhance its mechanical and functional properties. Iron(III) chloride hexahydrate (FeCl 3 ·6H 2 O) was integrated into the hydrogel to introduce magnetic functionality. Evaluation of the hydrogel's characteristics reveals successful cross-linking of the components as confirmed by FTIR analysis, while SEM images displayed consistent pore size and porosity. TGA indicated thermal stability in three degradation phases. XRD and SEM revealed a polycrytalline structure within a heterogeneous matrix having a rough, porous surface texture highly advantageous for improved fluid transportation and cellular movement. Electrical conductivity was measured using a four-probe tester, revealing that the hydrogel with 1.5% Na + CMC had the highest conductivity at 16 s/cm. In comparison, hydrogels with 1.0% and 0.5% Na + CMC showed conductivities of 10 and 6 s/cm, respectively. The hydrogel also exhibited good antibacterial effects against Staphylococcus aureus , methicillin-resistant S. aureus , and Escherichia coli . This versatile hydrogel has potential applications in medical and environmental fields.

For large-area electronic and high shape complexity structure applications, various solution-processable materials are chosen as dielectric layer due to their simple molding process via spin-coating, casting, or 3D printing at room temperature. Herein, the acrylic-ended fluorinated hyperbranched polyaryletherketone ( hb -P6FAEK-Ace) was used as the prepolymer and then, the composition of photosensitive resin formula was regulated by adjusting the addition ratio of hb -P6FAEK-Ace and diluents (acrylimorpholine [ACMO] 1,6-Hexanediol diacrylate [HDDA]). These photosensitive resin solutions showed the relative low viscosities ranged ranging from 18 to 253 mPa S at 100°C which was in favor of the future 3D printing method and printing accuracy. Then, the obtained UV-cured films show the maximum tensile strength up to 71.9 MPa and superior thermal properties with the T g of 157°C–177°C and T 5% of 314°C–351°C. Moreover, they also exhibited the good dielectric performance with dielectric constants of 2.43–2.20 and dielectric loss of 0.013–0.014 at 1 MHz–1 GHz. These abovementioned satisfactory performance could be ascribed to the aromatic skeleton of hb -P6FAEK-Ace, introduced polarizability-CF 3 groups and the inner cavities for the hyperbranched structures, also the precise control of formula composition. Additionally, the curing degree, shrinkage of solid, and moisture properties were also researched thoroughly. This work provides a simple formula design though to construct the high performance and low dielectric photosensitive resin for the requirements of microelectronic applications.

The development of flexible piezoresistive sensors has increasingly attracted widespread attention due to their various potential applications in wearable devices, human–machine interfaces, and health monitoring systems. Developing high-performance sensors that can accurately monitor movement and human health monitoring is very necessary. This study uses silver nanoparticles, MXene, and polypyrrole to prepare conductive fabrics based on various fabrics through layer-by-layer encapsulation. Finally, conductive fabrics with different layers were encapsulated to prepare a multilayer fiber sensor. Next, the series piezoresistive performance of sensors made of different fabric materials and sensors with different layers were tested. The experimental results show that the sensor prepared has the best performance when the selected fabric material is mulberry silk and the number of layers of the fabric is five. After testing, the sensitivity of the sensor is 4.9029 at low strain and 0.7901 at high strain. Moreover, it exhibits good stability during 1600 compression-release cycles and temperatures range from −20 to 60°C. The designed sensor performs well in motion and human physiological signal monitoring. This study provides new ideas and references for the design and research of multilayer fiber sensors.

The purpose of this paper is to study the stability, radical scavenging activities, and bio-safety of cysteine-conjugated hyaluronic acid nanoparticles (Cys- conj -HA NPs). Additionally, the feasibility of utilizing these NPs as drug delivery systems is discussed. The structures of synthesized Cys- conj -HA polymers were analyzed using 1 H nuclear magnetic spectrum ( 1 H NMR) and Fourier transform infrared spectroscopy (FTIR) spectra. The stability, radical scavenging activity, and bio-safety of fabricated Cys- conj -HA NPs were investigated. Transmission electron microscopy (TEM) photograph illustrated that Cys- conj -HA NPs possessed spherical shapes with an average diameter of approximately 230 nm. Furthermore, these NPs exhibited high stability at temperatures of 4, 25, and 37°C. Notably, Cys- conj -HA NPs demonstrated significant free radical scavenging capabilities. The high cell viability observed indicated the absence of cytotoxicity from Cys- conj -HA NPs. Additionally, bio-safety studies revealed that these NPs did not induce acute toxicity in the blood and viscera of cargo-free NPs treated mice. Elisa assays indicated that there was no significant difference in the concentrations of interferon-γ (INF-γ) and tumor necrosis factor-α (TNF-α) between Cys- conj -HA NPs and normal saline (NS) treated mice (ns, p > 0.05), suggesting the absence of an inflammatory reaction caused by these NPs. Consequently, it can be concluded that Cys- conj -HA NPs are sufficiently safe to be employed as a vehicle for delivering oxidizing drugs.

Ion exchange membranes of new chemistry based on polymer blends are proposed through a convenient solution-blending process using the hydrophobic commodity polymer polyvinyl chloride (PVC) and the hydrophilic polyvinylpyrrolidone (PVP), which are completely miscible. The pyrrolidone groups can be protonated to form oxonium ions, functioning as transient fixed positive charges for fractioning sulfuric acid and sulfates via diffusion. The influence of PVC molecular weight and the membrane composition on the physical, chemical properties, and mass transfer performance of PVC-PVP blend membranes was systematically investigated. After equilibrium in 2.68 mol/L sulfuric acid, the sulfuric acid, and water contents in the blend membranes increase with the increase of the membrane PVP contents (20–75 wt%). The permeability coefficients of sulfuric acid and ferrous sulfate for the blend membranes also exhibit a gradual increase. Membranes of mass transfer properties comparable to commercial ones can be easily obtained by tuning the membrane PVP contents. It is proved that the larger sulfuric acid permeability over sulfates (FeSO 4 as an example) is due to both larger solubility and diffusion coefficient of sulfuric acid in the membrane phase. The optimal PVC-PVP blend membranes have shown nice performance in fractioning sulfuric acid from sulfates, when treating titania waste acid. This study provides valuable guidance for the design of high-performance yet low-cost ion exchange membranes with pyrrolidone chemistry from commodity polymers for resource recovery.

Photothermal therapy is a promising adjunctive treatment technique requiring a nanoplatform with excellent biocompatibility, photothermal stability, and precise targeting capabilities. This study aims to develop such a nanoplatform by synthesizing two new manganese(II)-based coordination polymers. The polymers were created by integrating 1,4-bis(imidazol-1-yl)benzene with the ternary ligand tris( p -carboxyphenyl)phosphane oxide, resulting in the formulas {[Mn 3 (L) 2 (bib) 3 (H 2 O) 7 ]·12H 2 O} n (CP 1 ) and {[Mn(HL)(bib)]·H 2 O} n (CP 2 ). These structures, with large surface areas and porosity, enhance drug loading efficiency. Doxorubicin (DOX) was successfully incorporated into a biocompatible HA/CMCS hydrogel-CP composite (HA/CMCS-CPs@DOX), forming a robust nanotherapeutic platform. Under near-infrared light irradiation, these metal-hydrogel composites effectively induced localized hyperthermia, aiding ocular melanoma treatment. We evaluated the effect of HA/CMCS-CP 2 @DOX on the cell proliferation of the uveal melanoma cell line, and the regulatory effects of the system on lncRNA ARAP1-AS1/miR-149-3p/S100A4 were also explored.

The accumulation of copper ions in the environment can devastate the ecological systems and threaten the health of organisms. Consequently, the development of effective adsorbents to extract Cu 2+ from aqueous solutions is urgently needed. Here, the Zeolitic Imidazolate Framework-8 (ZIF-8)/polyacrylonitrile (PAN) nanocomposite fibers were synthesized by electrospinning and further characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). ZIF-8 powders were uniformly distributed on the surface of the nanocomposite fibers, and amide CO NH bonds were formed between the NH 2 groups of ZIF-8 and the CO groups of PAN. The ZIF-8/PAN nanocomposite fibers demonstrated an exceptional Cu 2+ adsorption capacity of 275.7 mg g −1 at pH = 4.0. The adsorption process adhered to the pseudo-second-order kinetics and the Langmuir isotherm model. The adsorption mechanism, as conformed by FTIR and X-ray photoelectron spectroscopy (XPS) analysis, involves the coordination of the NH 2 and CO groups with Cu 2+ and the ion exchange processes between Cu 2+ and Zn 2+ for the nanocomposite fibers. This study provides a novel approach for the removal of Cu 2+ from aqueous solutions and addresses the challenge of recovering powder materials in wastewater treatment.

The development of hydrogel wound dressings that facilitate rapid healing is a complex task, primarily due to the necessity of integrating multiple functional attributes, including air permeability, adhesion, antibacterial efficacy, and biocompatibility. In this study, we employed fatty acid-modified carboxymethyl chitosan (CMCS) to fabricate a multifunctional antibacterial hydrogel dressing. This dressing exhibits adjustable hydrophobicity, robust mechanical properties, and potent antibacterial activity, with polyacrylamide (PAM) and tannic acid (TA) serving as the primary constituents. The study demonstrated that the incorporation of hydrophobic structures significantly enhanced the tensile strength, compressive properties, and adhesive capacity of hydrogels. In addition, the release curve of TA showed that fatty acids played a vital role in enhancing the antibacterial properties of hydrogels, which may increase the release of TA. Furthermore, the length of the carbon chain has a significant effect on the mechanical properties and hydrophobic properties of the hydrogel. In summary, the TA/(C14-g-CMCS)/PAM hydrogel has excellent antibacterial properties, which can effectively prevent bleeding, accelerate wound closure, and promote tissue regeneration. Therefore, the TA/(FA-g-CMCS)/PAM hydrogel with adjustable hydrophobicity is expected to be the best candidate for accelerating wound healing and promoting rapid regeneration of skin tissue.
