Wet-tissue adhesives face challenges in achieving tough wet adhesion because the hydration layer on the tissue surface hinders the formation of interfacial bonds. Inspired by the cation-mediated wet adhesion in barnacles, a strong wet tissue adhesive hydrogel, P(mPEI-AA-AMH 1 ), is prepared by photo-initiated copolymerization of acrylic acid (AA), cationic monomer (AMH) and modified polyethyleneimine (mPEI). mPEI is a kind of polyelectrolyte containing various amino cations and carbon–carbon double bonds, which helps to enhance the wet adhesion and mechanical properties of the hydrogel. Its adhesion strength on moist porcine skin is ~115 kPa, while the interfacial toughness on moist porcine skin is ~422 J/m 2 , which can effectively close rat femoral artery wound. Additionally, the hydrogel exhibits good antibacterial properties and biosafety. The antibacterial efficacy of the P(mPEI-AA-AMH 1 ) hydrogel against E. coli reaches an impressive 99.23% ± 0.24%, and against Staphylococcus aureus reaches 99.1% ± 0.45%. The P(mPEI-AA-AMH 1 ) hydrogel has good tissue-selective adhesion due to its hydrogen bonding and electrostatic interactions with the negatively charged tissue surface. It shows minimal adhesion to medical devices and is easy to apply, which is expected to provide theoretical support for the future development of wet adhesive hydrogels in medical applications.

Mixed matrix membranes (MMMs) incorporating metal–organic frameworks (MOFs) as fillers show attractive selectivity and permeability for gas separation. However, the performance improvement is restricted by undesirable interfacial interaction and inhomogeneous dispersion of MOFs in the membrane matrix. In this paper, amino-functionalized UIO-66 (U6N) with high porosity was employed as a filler and further regulated by a controlled plant polyphenol-induced surface modification strategy. The process involved the formation of tannic acid-iron(III) complex (TA-Fe(III)) on the U6N surface, which improved interfacial compatibility with the polyimide matrix while introducing abundant hydroxyl groups to enhance gas transport properties. Accordingly, the modified MMMs containing 30 wt.% U6N@TA-Fe(III) achieved optimized gas separation performance. Specifically, the CO 2 permeability increased to about 2495.9 Barrer with a CO 2 /CH 4 selectivity of 19.32, which exceeded the 2008 Robeson upper limit and showed an increase of 22.1% and 25.6%, respectively, compared to the MMMs embedded with unmodified U6N. Moreover, the improved dispersion of the U6N@TA-Fe(III) within the membrane structure is conducive to improving separation performance for CO 2 /N 2 and O 2 /N 2 . Therefore, this work provides a novel insight into the rational design of the MMMs via a facile modification strategy, which can further improve the gas separation performance of the MMMs.

Poly(ethylene oxide) (PEO) is a promising candidate to fabricate solid polymer electrolytes (SPEs). To improve the comprehensive performances of PEO-based SPEs, vinylidene fluoride (VDF) copolymers grafted with poly(ethylene glycol) were electrospun and applied as a support for the PEO matrix. The grafting of PEG onto the VDF copolymer was achieved by the nucleophilic substitution of a chlorine atom in the VDF copolymer by methoxy-polyethylene-glycol thiol. The ionic conductivity of the VDF copolymer was increased with the grafting site density of PEG at the same bis(trifluoromethane sulfonimide) (LiTFSi) concentration. SPEs were fabricated by solution casting of PEO/LiTFSi onto electrospun VDF graft copolymer fibers. Electric field poling induces a beneficial α -to- β phase transition in the VDF copolymer, and the compatibility between the VDF copolymer and PEO was improved due to the incorporated PEG side chains, which facilitate lithium ion (Li + ) transport through additional conduction pathways and enhance lithium-ion solvation. The supported PEO SPEs exhibited good mechanical strength and toughness, and the optimized SPE with an EO/Li ratio of 6:1 exhibits excellent electrochemical performance at 60°C, including an ionic conductivity of 1.79 × 10 −4 S cm −1 , a Li + transference number of 0.49, and a wide ESW of 5.46 V (vs. Li + /Li).

Amid the global “double-carbon” initiative, melting-grafted polypropylene (PP) insulation presents a promising technical route for next-generation power cable systems due to its recyclability, satisfactory dielectric performance, and engineering practicality. However, its universality across both high-voltage alternating current (HVAC) and direct current (HVDC) systems remains to be fully assessed. In this study, we selected a mature polar grafted PP system: glycidyl methacrylate (GMA)-grafted PP, to experimentally evaluate its performance and elucidate the underlying physical mechanisms. The results demonstrate that GMA-grafted PP exhibits excellent DC dielectric performance, including a 24.6% enhancement in breakdown strength and significantly improved space charge distribution, whereas its performance under AC conditions remains unsatisfactory. The GMA-induced trapping-detrapping process is proved a key factor contributing to DC improvements, while the study also highlights that polymeric degradation during the melting grafting process, as well as the high polarity of GMA, are responsible for the unfavorable AC performance. In conclusion, 5% (weight percent) GMA-grafted PP is highly suitable for HVDC cable insulation, but the degradation associated with the melting grafting process is a crucial and urgent issue to be addressed, for the development and universality of high-capacity recyclable cable systems.

The current preparation of biomass-based hydrophobic absorbents still relies excessively on the use of fluorinated hydrophobic substances, which poses a risk of environmental pollution. This study aims to develop a sustainable and nonfluorinated method for fabricating biomass-based hydrophobic absorbents with enhanced recyclability and multifunctional surface properties. The chemical vapor deposition method based on nonfluorinated methyltrichlorosilane is used for the in situ growth of polysiloxane nanofilaments on the surface of Tong Cao (TC), resulting in the development of a TC-based hydrophobic absorbent. Upon organosilane modification, modified TC shows good hydrophobicity with a water contact angle of 93° and can be used to remove organic solvents from water. The absorption capacity of modified TC for different organic solvents is from 3.1 to 6.5 g/g. The percentage of retained absorption capacity of modified TC still remains at 98% after 10 consecutive uses, demonstrating a good recyclability. Modified TC also holds high organic solvents retention capacity as well as good self-cleaning and anti-fouling ability. These results indicate that modified TC with hydrophobicity and recyclability has potential for practical oily wastewater treatment.

This study employed a two-step approach involving melt polycondensation and chain extension to synthesize high-molecular-weight PLA. Initially, the mechanism of ring-forming side reactions during polycondensation was systematically investigated using MALDI-TOF-MS. The results demonstrated that the SnCl 2 /TSA composite catalyst effectively suppressed the formation of cyclic oligomers, and the optimal reaction conditions were determined as 180°C for 8 h. Based on these findings, HDI was chosen as an efficient chain extender. By optimizing both the molecular weight of PLA during polycondensation and the HDI content, chain-extended PLA with a molecular weight of 1.48 × 10 5 g/mol was successfully obtained. The results showed that the chain-extended product exhibited excellent overall performance. Its tensile strength (75.5 MPa) was comparable to that of commercial PLA 4032D (75.3 MPa), while its elongation at break (12.21%) slightly exceeded that of the commercial sample (11.1%). This work provides a novel strategy for the industrial production of high-performance PLA.

To leverage strong P/N synergistic effects to impart high flame retardancy to epoxy resin without compromising overall performance, a novel flame retardant, 6-(pyrimidin-2-ylamino)dibenzo[c,e][1,2]oxaphosphinine 6-oxide (DAP), was synthesized by forming a P–N bond between 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO) and 2-aminopyrimidine. Its structure was confirmed by NMR and mass spectrometry. Non-isothermal DSC tests demonstrated that DAP acted as a co-curing agent with 4,4′-diaminodiphenylmethane for diglycidyl ether of bisphenol-A and enhanced the curing rate. DAP significantly enhanced the flame retardancy of the epoxy resin at a low loading of 4 wt% (0.40 wt% phosphorus), achieving a limiting oxygen index (LOI) of 32.1% and a UL-94 V-0 rating. It also reduced heat and smoke release. The results from dynamic mechanical analysis (DMA) and mechanical property tests showed that the epoxy resin containing 4 wt% DAP retained a glass transition temperature comparable to the neat resin, along with slight improvements in mechanical properties, including flexural strength and modulus, non-notched impact strength, and tensile strength. The analyses of UL-94, cone calorimetric test (CCT), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis/infrared spectroscopy (TGA/IR), and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) revealed that the flame-retardant mechanism involved both a condensed-phase char barrier and gas-phase quenching and dilution effects.

Aramid fiber (AF)-reinforced composites face significant limitations in applications such as deep-sea equipment and aerospace due to their poor interfacial compatibility and low bonding strength. This study presents an innovative and scalable strategy for constructing a nano-hierarchical reinforcement interface on AF to fundamentally address this issue. A multifunctional interlayer was first constructed using polyethyleneimine (PEI) and polydopamine (PDA), on which both carboxylated and aminated carbon nanotubes (COOH-CNTs and NH 2 -CNTs) were co-anchored to produce the final product, denoted as C/N-CNTs-PP-AF. The distinctive dual-CNT configuration produced a stable electrical resistance in the range of 51.57–84.20 MΩ by forming a continuous conductive network. More importantly, C/N-CNTs-PP-AF/unsaturated polyester (UP) composites exhibited significant enhancement in properties, which corresponded to an interfacial strength of 39.60 MPa (an 81.15% increase) and tensile strength of 1404.25 MPa (an 89.45% improvement). The approach leverages multifaceted interfacial interactions to enable stable CNT grafting and enhanced adhesion. This work not only effectively addresses weak bonding at the AF/UP interface but also establishes a new paradigm for the design of high-performance fiber-reinforced composites with integrated functionalities.

Information storage materials with color-changing capabilities have garnered widespread attention for their ability to efficiently record complex information. In recent years, oriented hydrogels have made significant progress in the fields of information storage and encryption because of their rich and unique interference colors. However, introducing anisotropic microstructures in oriented hydrogels to rapidly create interference patterns remains a challenge. Additionally, interference-color-based encryption strategies remain limited and require further improvement. In this paper, a thermally responsive poly(vinyl alcohol) (PVA) hydrogel was fabricated through a stretch-induced combined with ion-assisted hydrogen bonding reconstruction strategy. A pen-tip soldering iron used as a contact thermal stimulus can rapidly dissociate the localized PVA crystalline domains, enabling the real-time creation of interference patterns. Moreover, innovative encryption strategies were proposed based on the angle-dependent properties of interference colors. By combining the hydrogels with different orientations and rotating them at different angles, the display of different pattern information was successfully realized. This approach avoids the complex steps of traditional interference-pattern preparation and offers a new paradigm for employing hydrogels in information encryption.

Thermal insulation materials are essential for preserving human warmth in cold climates, and biomimetic strategies inspired by natural structures offer powerful design principles. Motivated by the feather architecture of penguins, which endure year-round temperatures of approximately −40°C to −60°C, a high-performance thermal-insulation (HPTI) material that reproduces the key features of feather structure by balancing thermal resistance, ultralow mass, and mechanical flexibility is reported. The HPTI is fabricated via a two-step electrospinning process with tailored spinning parameters to produce a hierarchical, feather-like architecture: a fluffy, air-holding polyimide (PI) nanofiber aerogel paired with a compact PI nanofiber windproof membrane, yielding an ultralow bulk density of 4.15 mg/cm 3 . Surface hydrophobicity is excellent, with water contact angles of 147° (aerogel) and 130° (windproof membrane). The assembled material with an areal density of 190 g/m 2 achieves a thermal-insulation ratio of 97.81%, a clothing insulation (clo) value of 6.518, and a heat-transfer coefficient of 0.72 W/K·m 2 . Combined with favorable compressibility and mechanical compliance, these characteristics make the HPTI a promising candidate for lightweight, flexible garments and protective systems intended for extreme-cold applications, while offering a scalable route to bioinspired thermal-management materials.

To increase the toughness of epoxy resin, an allyl-terminated furanylbenzoxazine (AFB) derived from eugenol was copolymerized with epoxy resin (E51). Fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) analyses were used to examine the curing behavior of the blended resins. With increasing AFB content, the crosslinking density of the EP-AFB resins decreases, while the residual carbon yield ( Y c ) of the epoxy resins after high-temperature combustion in a nitrogen atmosphere increases. The Y c of EP-4AFB increased from the initial 14.92% to 20.21%. In addition, appropriate concentration of AFB could be conducive to improving the mechanical properties. The flexural and impact strengths of EP-1AFB resins were 3.5% and 81.3% higher than EP resins, respectively. The elongation at break and tensile strength of EP-3AFB resins were 91.2% and 68.4% higher than EP resins, respectively. Furthermore, the addition of AFB significantly modified both adhesive (lap shear strength and peel strength) and dielectric properties of the epoxy resins.

Due to the environmental concerns associated with zinc oxide, there is growing momentum toward limiting its usage, particularly in the rubber tire industry. However, reducing ZnO content in tire manufacturing remains a significant challenge, primarily because the activation mechanism of ZnO has not yet been fully elucidated. In this work, three types of ZnO with different surface structures were synthesized, and the activation effects of various atomic structures on ZnO facets toward sulfur and the accelerator N-cyclohexyl-2-benzothiazole sulfonamide (CBS), were studied through experiments and density functional theory calculations, ultimately converging on the same conclusions: Zn 2+ located in the outermost layer of the ZnO (0 0 1) facet can significantly facilitate the cleavage of S-S bonds in sulfur and N-S bonds in the accelerator CBS. The ZnO (1 0 0) facet comprises two energetically distinct surfaces: the high-energy (H-(1 0 0)) facet, which exposes two-coordinate zinc, exhibits relatively high surface reactivity and moderately promotes the decomposition of sulfur and CBS; while the low-energy (L-(1 0 0)) facet, dominated by three- coordinate zinc, which is more prevalent but possesses lower surface reactivity. The prevalence of L-(1 0 0) reduces the overall activation efficiency of ZnO (1 0 0) for sulfur and CBS decomposition.
