The growing demand for stretchable electronics is driving the development of better stretchable conductive sensors. Herein, we present a simple in situ fabrication strategy for constructing wrinkled silver nanowire (AgNW) networks, enabling high-performance stretchable electronics. AgNWs are first vacuum-filtered onto an electrospun polyurethane–urea (PUU) mat. A subsequent thermal treatment then simultaneously induces wrinkling and partially embeds the network within the elastic substrate. The fabricated conductive films exhibit outstanding electromechanical performance, featuring exceptional stretchability (> 900% elongation at break), with minimal resistance variation (Δ R / R 0 = 1.35 at 120% strain and 9.9 at 240% strain). They maintain excellent cycling stability over 1000 stretch/release cycles at 50% strain, coupled with remarkably low initial resistance (50 mΩ/sq) and high conductivity (5.02 × 10 6 S/m). Functioning dually as a stretchable electrode and strain sensor, the AgNW/PUU composite provides both electrical conduction and mechanical sensing capabilities. Notably, the embedded AgNWs network inherently provides antibacterial properties (> 99% bacterial reduction) and biocompatibility, while the wrinkled morphology enhances interfacial contact with biological tissues, rendering the conductive films particularly suitable for bio-integrated electronic devices. Crucially, the current AgNW-based conductive films exhibit random wrinkle patterns, making them withstand complex, multi-axial deformations in wearable applications.

The growing demand for multifunctional sensors in wearable systems has prompted the need for materials that simultaneously support gas sensing and mechanical strain detection. However, current flexible sensing materials still suffer from issues such as response hysteresis, poor humidity resistance, and lack of antibacterial properties. Herein, we developed a ternary flexible composite by integrating defect-engineered ZIF-8, conductive polypyrrole (PPY), and bacterial cellulose (BC), which was further encapsulated with polydimethylsiloxane (PDMS) to form the Def-ZIF-8/PPY/BC@PDMS composite. The results demonstrated that with 2–3 layers of PDMS, the sensor achieved a fast and stable NO 2 response (9.3% at 10 ppm), with reliable recovery. Under 80% relative humidity, PDMS reduced humidity-induced signals from 34% to 10.3%, confirming markedly improved moisture resistance. The incorporation of a PDMS layer enabled enhanced stress sensing, reducing the response/recovery times to 0.4/0.3 s from 0.9/0.8 s in the uncoated structure. The sensor demonstrated high fidelity in recognizing complex biomechanical signals such as swallowing, walking, and finger articulation. Furthermore, antibacterial testing confirmed 42.18% and 64.69% inhibition against Escherichia coli and Staphylococcus aureus , respectively. This multifunctional composite simultaneously optimizes gas sensing, mechanical flexibility, humidity resistance, and antibacterial efficacy, paving the way for advanced materials in fully integrated wearable sensing technologies.

With the decreasing of petrochemical resources and the increasing severity environmental pollution, the development of environmentally friendly adhesive technology using renewable resources has attracted more and more attention. Inspired by mussels, a novel biomimetic adhesive synthesized using polyaspartamide derivative (PolyAspAm(DOPA/OA)) and alkali lignin (AL). The physical/chemical structure and properties were examined by 1 H-NMR, Fourier-transform infrared spectroscopy, thermo gravimetric analysis, scanning electron microscopy, water absorption, in vitro cytotoxicity, lap shear tensile, and three-point bending tests. The adhesive capacity was improved significantly when AL added into PolyAspAm(DOPA/OA). The lap shear tensile for four different substrates (metal and plastic) both increased greatly. The underwater adhesion test possessed good underwater adhesion properties. The results confirmed that hydrogen bonds and chain entanglement were formed between PolyAspAm(DOPA/OA) and AL. It was the introduction of catechol groups and physical–chemical interactions between PolyAspAm(DOPA/OA) and AL improved the adhesion strength and water resistance of the adhesive. Moreover, the corn stover non-wood boards were prepared by one-step hot pressing using PolyAspAm(DOPA/OA) with AL adhesives. The three-point bending of corn stover non-wood boards increased from 5.00 ± 0.03 to 14.85 ± 20.1 MPa. Overall, this work shows that a nontoxic, environmentally friendly PolyAspAm(DOPA/OA) with AL adhesive has extensive application prospects.

The poor plasticity of coal results in a large amount of dust during the mining process, thereby posing a significant impact on mine safety and the health of workers. In order to address this issue, a method has been proposed to suppress dust by enhancing the plasticity of coal through injecting a reactive material, which forms a colloid within the coal. The results implicated that the self-active colloidal dust suppressant, composed of sodium alginate, gluconolactone, calcium disodium EDTA, and sodium dodecyl sulfate, effectively improved the moisture content of coal seams and decreased the brittleness of coal. Scanning electron microscopy and specific surface area test revealed that the dust suppressant not only tightly adheres to the surface of the coal after the reaction, but also penetrates the coal pores and forms a colloid on both the inner and outer surfaces of the coal. The material is rich in carboxyl and hydroxyl groups, which forms hydrogen bonds with the carboxyl and hydroxyl groups present in coal. This interaction enhances the toughness of coal. Simultaneously, it has the ability to adsorb water and function as a moisturizer. The combined synergistic effect of these mechanisms fundamentally reduces dust production during the coal mining process.

In this work, semi-aromatic polyamide containing ether bond (PAE10T) was synthesized through nucleophilic substitution reaction using 1, 10-N, N′- bis (4-fuorobenzamide) decane (BFBD) and hydroquinone (HQ) as the raw materials. And then the composites hydroxyapatite/semi-aromatic polyamide (40%HA-PAE10T and 60%HA-PAE10T) were prepared by chemical precipitation method. Mechanical, SEM, FT-IR, XRD, DSC, TGA and bioactivity tests were performed to characterize the structure, morphology, thermal and mechanical properties of PAE10T and its composites. Mechanical tests revealed that the difference of HA in weight played an important role in mechanical performance of the composites. Furthermore, in comparison with PAE10T, the 60%HA-PAE10T showed the highest enhancement in compressive strength (133 MPa) at 75.9%, and the 40%HA-PAE10T given expression to the best increase in bending strengths (97 MPa) at about 18.4%. The 40%HA-PAE10T and 60% HA-PAE10T exhibited the mechanical performances closed to the cortical bone of human. After 28 days of dip in the phosphate buffer saline (PBS), PAE10T, and its composites showed satisfactory stability. The cell culture results showed all composites gad good cytocompatibility, cells attached on the materials well with excellent morphology. All the experimental results showed that the composites were expected to have a good application in the field of compact bone repair.

A series of poly(ester imide) (PEsI) copolymers were synthesized using 3,3′,4,4′-biphenyltetracarboxylic dianhydride (4,4′-BPDA), 2,2′-bis(trifluoromethyl)benzidine (TFMB), and 4-aminophenyl-4′-aminobenzoate (APAB) as the monomers. Wide-angle x -ray diffraction results revealed that the average interchain distances of these polymers ranged from 4.6 to 5.7 Å, increasing with the increase of TFMB contents. PEsI-0.3 and PEsI-0.4 exhibited a glass transition temperature ( T g ) of 445 and 455°C, respectively, while no distinctive T g was observed for the PEsI copolymers when the APAB content was >50 mol%. The coefficients of thermal expansion (CTE) of these PEsI copolymers ranged from 3.8 to 24.2 ppm K −1 , increasing with the increase of TFMB contents. The PEsI copolymers exhibited a modulus of 5.7–7.8 GPa, a tensile strength of 282–332 MPa, and an elongation-at-break of 10.2%–23.3%. Furthermore, these copolymers exhibited a dielectric constant of 2.53–2.76, and a low dissipation factor ( D f ) of 0.0026–0.0032 at 10 GHz in dry state. Because of their excellent combined properties, these PEsI copolymers are promising candidates as dielectric substrate materials for the applications in next generation flexible printed circuit boards operating at high frequencies.

Superhydrophobic three-dimensional porous materials have been considering as one of the most promising candidate absorbents for removal and collection of oil spills or organic contaminants from water. In this work, we report a novel and straightforward method for construction of hierarchical superhydrophobic surfaces on the commercial melamine sponge by controlling of the dopamine oxidative selfpolymerization via a gradient of ammonia content. The surface roughness of the sponge was enhanced by the deposited polydopamine coatings whose surfaces exhibited different morphologies at solutions of varied ethanol-ammonia ratios. Thereafter the low-surface free energy moieties were decorated on the surfaces by utilizing a secondary modification platform of polydopamine. Correspondingly, the obtained superhydrophobic melamine sponge achieved a water contact angle of 162.6° ± 1. Furthermore, the superhydrophobic sponge exhibited excellent absorption performances and extraordinary recyclabilities toward a variety of oils and organic solvents. These findings presented in this study offer an effective and versatile approach for oil spills and organic solvents containment removal and environmental remediation in more fundamental and practical fields. © 2019 Wiley Periodicals, Inc.

In this study, a novel photo-crosslinked polymer composite was made from NCO-terminated fluoropolymers by the incorporation of functionalized graphene through the in situ polymerization method. This polymer composite can be photoinduced to form a network under UV radiation without photoinitiators, displaying an excellent transmittance (T% > 90% at 550 nm), a high thermostability with a glass transition temperature ( T g < −15 °C), and a 10% weight loss temperature (410 °C). With UV radiation, the hybrid coating exhibited a controlled releasing force between 100 and 500 g/25 mm for silicone PSAs, which was an important breakthrough in the heavy-releasing industry. Their aging releasing performance and residual adhesion force were satisfactory. More importantly, antistatic agents are not needed any more before the coating of this novel releasing agent. In addition, the coating possessed good hydrophobicity with a contact angle of 110° and great resistance to solvents. These metrics indicate that incorporating functionalized graphene as curable points into composites can greatly improve the performance of fluoropolymer properties. The obtained polymers have potential applications in the releasing and protective industry. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 48322.

Smart gene delivery vectors are gaining increasing attention in gene therapy, owing to their low cytotoxicity and intrinsic responsiveness. Our previously fabricated novel cationic brush polymer, comprising C Se bonds and tertiary amine EGIn- g -PDMAEMA, shows potential for gene transfection. In this study, its high efficiency for siRNA/pDNA transfection and low cytotoxicity in reactive oxygen species (ROS)-rich microenvironments is substantiated in vitro. Its superior binding capacity with siRNA/pDNA is confirmed by agarose gel electrophoresis assay. The threshold weight ratios for siRNA/pDNA migration delay are 15 and 3 (polymer-to-nucleic acid, w/w), respectively. Fluorescence microscopy and ribonucleotide reductase regulatory subunit M2 gene silencing essay verify the biodegradability and responsive control release of nucleic acids under hydrogen peroxide stimulation in Huh-7 cells. Compared with the gold standard, polyethylenimine 25 kDa, the target polymer displays superior transfection efficiency in ROS-rich tumor cells under serum-free conditions. Furthermore, the vector–nucleic acid complexes exhibit over 90% cell viability at a high concentration of 12 μg mL −1 and good colloidal stability in phosphate-buffered saline (PBS) and 10% fetal bovine serum-PBS for 24 h. The efficient control release and expression of nucleic acids in ROS environments and reduced cytotoxicity highlight the superiority of EGIn- g -PDMAEMA as a gene delivery platform for tumor gene therapy.

Novel hypercrosslinked microporous organic polymers (MOPs) derived from N-functionalized siloles as basic building units have been designed and synthesized via Friedel–Crafts alkylation reaction. The resulting N-functional silole-containing polymer networks exhibit high thermal stabilities and moderate Brunauer–Emmett–Teller surface area ranging from 666 to 1137 m 2 g −1 . The incorporation of carbazole or triphenylamine moieties into the polymer skeleton increases the number of electron donating basic nitrogen sites in the porous frameworks. Thus, the corresponding polymer PDMCzS shows enhanced CO 2 adsorption capacities of 3.23 mmol g −1 at 273 K and 1.13 bar, and higher CO 2 /N 2 selectivity (43.99) at 273 K than the analogous silole-containing polymers P1–P3. These results demonstrated that the N-functionalized silole-containing polymer network is a very promising candidate for potential applications in post-combustion CO 2 capture and sequestration. © 2017 Wiley Periodicals, Inc.

Three derivatives of bis-styrybiphenyl with different degrees of sulfonation to be used as fluorescent whitening agents (FWAs) were synthesized. Studies on their spectroscopic properties were performed using a combination of computational methods. Whitening effects of FWAs and the improved thermal stability of polypropylene (PP) were investigated. The morphology of plastic samples was examined by scanning electronic microscopy (SEM). In order to improve the compatibility between FWA and PP, PP grafted with maleic anhydride (MAH) was applied as compatibilizer. The optical properties were further clarified by the results of frontier molecular orbital modeling, which show that the presence of sulfonic sodium group leads to a red shift of maximum UV absorption wavelength and a low HOMO–LUMO energy band gap. It is observed that the addition of 0.010 wt % of the sulfonated FWA would result in the expected whitening effect as well as improved PP thermal stability, while at or above 0.015 wt %, such effects worsen sharply owing to phase separation. Furthermore, the use of MAH-grafted PP as compatibilizer results in improvement of phase behavior and thermal stability. The study provides new insights into the effect of FWA structure on the properties of PP that are related to the whitening of the material. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Transparent polymer with excellent heat resistance and mechanical properties play an important role in many fields. However, transparent polyetheretherketones films are rarely reported, probably due to their high crystallinity. In this work, a transparent polymer polyetherketone was prepared from the reaction of 4,4′-difluorobenzophenone, 2,6-bis(4-hydroxybenzylidene) cyclohexanone, and tert-butylhydroquinone in the presence of K 2 CO 3 . This new polymer has excellent thermal stability, high glass transition temperature (T g = 172°C), good film-casting property, high transparency, good hydrophobicity, and low saturated water absorption (0.52%). The material has broad application prospects in flexible solar cells, UV protection, and thin insulation materials.
