Epoxy resins are widely utilized in many fields due to their good mechanical properties, thermal properties, and chemical stability. However, most of the reported epoxy resins are characterized as nondegradable and nonrecyclable thermosetting materials, causing great environmental pollution and resource waste. Herein, we report a fully bio-based and recoverable epoxy resin using a bio-based epoxy monomer and curing agent. The epoxy monomer (VAN-TA-EP) was synthesized by a Schiff base reaction based on vanillin (VAN) and Tris(2-aminoethyl)amine (TA) and further epoxidated. The bio-based imine curing agent (DI) was synthesized from diformylfuran (DFF) and isophorone diamine (IPDA). The resultant epoxy resin TA/DI that composed of VAN-TA-EP and DI, showed high performance, degradability, and recyclability. The tensile strength of the prepared bio-based epoxy resin reached a maximum of 104 MPa, which is significantly higher than that of the conventional DGEBA/DDM (59 MPa). The epoxy resin was demonstrated to be heated and reshaped by the imine metathesis, which was experimentally confirmed. Furthermore, the cross-linked resins have good degradability to the acid- or base-induced hydrolysis of imine bonds. This study paves the way for the preparation of high-performance and recyclable bio-based epoxy resins.

Due to the increasingly stringent environmental regulations and the great demand for sustainable materials, fluorine-free water- and oil-resistant coatings for paper have attracted considerable attention in the field of packaging and decoration. In this study, acrylated epoxidized soybean oil (AESO) and pentaerythritol tetrakis(mercaptoacetate) (PETMA) were used as reactants to form a crosslinked film on kraft paper through a UV-initiated thiol-ene click reaction, followed by the spraying of a mixed dispersion of silica (SiO 2 ) and AESO/PETMA solution, and a fluorine-free water- and oil-resistant composite coating on kraft paper was obtained. When the molar ratio of CC bonds of AESO to SH groups from PETMA was 1:1 and the content of SiO 2 was 20% of the mass of AESO, the water contact angle of the coated paper reached 141°, far higher than that of the uncoated paper at 56.5°. Meanwhile, compared with uncoated paper, the Cobb 60 value of the coated paper sharply decreased from 67.1 to 1.4 g m −2 , demonstrating excellent water resistance. In addition, the oil contact angle of the coated paper also attained 137°, and kit rating of 12/12. The coated paper also exhibited excellent barrier properties to hot castor oil.

A predrug delivery system combining tumor-targeting and pH-responsive features was synthesized using baicalin (BAI), polyethylene glycol (PEG), and folic acid (FA). BAI and PEG were linked via esterification to create pH-sensitive ester bonds ( COO ) that facilitate drug release in acidic environments, while FA was attached to PEG through substitution. This system, named FA-PEG-COO-BAI (FPB), encapsulated curcumin (CUR) to form drug-loaded micelles. The impact of drug-loading conditions, such as sonication duration and initial drug dosage, on CUR/FA-PEG-COO-BAI encapsulation efficiency and drug release was investigated. In vitro studies demonstrated a maximum encapsulation rate of (73.09 ± 3.31)% and a drug-loading rate of (11.90 ± 0.69)%. Drug release from CUR/FA-PEG-COO-BAI micelles accelerated as pH decreased, confirming pH-responsive behavior. Cellular uptake and antitumor assays suggested effective tumor targeting and inhibition of proliferation. Hemolysis and cell viability assays indicated low toxicity. These findings underscore the potential of CUR/FA-PEG-COO-BAI micelles for controlled drug release and targeted therapy.

Polymer is the dielectric material of choice for dielectric capacitors. However, the low dielectric constant limits the polymer from achieving a satisfactory energy density. Therefore, researchers synergistically integrate a variety of components to effectively improve the energy storage performance. In this paper, Polyetherimide (PEI) and Fluorene Polyester (FPE) hybrid composite films are prepared by a linear/linear blending strategy. The dielectric constants of PEI and FPE are 3.38 and 3.45 at 10 Hz, and the dielectric constant is increased to 4.02 when the mass fraction of FPE is 10%. The breakdown field strength of PEI and FPE is 553.51 and 589.34 kV/mm, and the breakdown field strength reaches 746.51 kV/mm after blending. At 800 kV/mm, the energy storage density and energy storage efficiency of the hybrid composite film reach 11.38 J/cm 3 and 86.14%. Compared with PEI, the performance of the prepared blended composite film has been comprehensively improved, which provides a corresponding theoretical analysis and experimental strategy for the preparation of high-performance all-organic blended composite dielectric and also has potential application prospects in energy storage devices.

Renewable and degradable pressure-sensitive adhesives (PSAs) have emerged as promising green alternatives in the adhesive industry, addressing both petroleum resource depletion and plastic pollution challenges. This work is to provide a design and preparation of high-performance biodegradable bio-based thermoplastic polyurethane pressure-sensitive adhesive(TPU-PSAs) to solve the problem that most PSAs are nondegradable, nonrenewable, and nonrecyclable. Through a solvent-free one-step polymerization process, we synthesized bio-based TPU-PSAs using polylactide diol (PLA), polycaprolactone diol (PCL), and polytetramethylene ether glycol (PTMEG) polyols with varying NCO/OH ratios. Through the correlation analysis of microphase separation morphology, viscoelastic response, and macroscopic adhesion behavior, the structure-performance relationship of the system was established, which promoted the rational design of sustainable adhesives. Notably, HS (30)/0.8 (NCO/OH = 0.8) demonstrated exceptional peel strength (7.5 N/cm) coupled with substantial biodegradability (56.4% degradation within 8 weeks). Meanwhile, HS (30)/1 (NCO/OH = 1) exhibited superior shear resistance (368 kPa on glass substrates) without requiring cross-linking agents. These TPU-PSAs showcase a unique combination of tunable viscoelastic properties through controlled microphase separation, positioning them as promising candidates for sustainable adhesive applications that demand biodegradability, recyclability, and renewability.

Slippery liquid-infused porous surfaces (SLIPS) typically suffer from inadequate stability due to poor matrix-lubricant interactions. To address this limitation, we developed a novel epoxy resin/polydimethylsiloxane (EP/PDMS) composite porous membrane through a rational structural design. The system employs epoxy resin as a “hard segment” to provide strong adhesion and friction resistance, while polydimethylsiloxane serves as a “soft segment” to impart flexibility and hydrophobicity. The composite was synthesized via an epoxy-amine addition reaction, and hydrophilic calcium sulfate whiskers (CSW) were hydrophobically modified with stearic acid (SA-CSW) and physically incorporated into the polymer matrix. A stable porous structure was fabricated using the breath-figure method, and after silicone oil infusion, an ultra-smooth surface was obtained. Systematic investigation revealed that the optimal performance was achieved with 5% SA-CSW content, an amino-terminated polysiloxane to epoxy resin ratio of 1.5:10, and a coating concentration of 20 mg/mL, resulting in a remarkably low sliding angle (SA) of 5°. Comprehensive characterization including FTIR, XPS, TGA, and SEM confirmed the successful construction of the composite structure and its excellent stability. The developed SLIPS demonstrate outstanding comprehensive properties including superior oil retention, enhanced mechanical durability, excellent lubrication performance, and effective antibacterial capability, providing a reliable solution for stable lubricant-infused surfaces.

Conductive hydrogels have great potential as flexible sensors in wearable devices. However, it remains a challenge to integrate excellent mechanical properties, high conductivity, and sensitivity into hydrogels using simple green methods. Here, cellulose nanofibers (CNFs) and MXene were introduced into a polyvinyl alcohol (PVA) hydrogel system based on the multi-scale synergistic enhancement mechanism of nanocomposites. By forming interfacial hydrogen bonds and entanglement of molecular chains, a nanofiber-reinforced PVA/CNF/MXene (PCM) hydrogel was developed. MXene enhances the electrical conductivity of the hydrogel, reaching 0.175 S/m, which represents a 191.7% increase compared to the hydrogel without MXene. The synergistic enhancement between CNF and MXene confers the PCM hydrogel with high mechanical strength (334 kPa) and high stretchability (339%). Moreover, PCM hydrogel serves as a strain sensor with outstanding strain sensitivity (GF = 3.25), wide dynamic detection range (0%–220%), and low detection threshold (0.3%), demonstrating excellent stability and durability in response to stimulus signals. The hydrogel sensor enables accurate detection of subtle human movements and synchronized control of robotic arms, demonstrating its broad applicability in motion monitoring and human–machine interaction (HMI).

The enzymatic coagulation process has emerged as a promising natural rubber (NR) processing method because of its high efficiency and environmental friendliness. However, the structural evolution of enzyme-treated NR during storage and its consequent effects on the properties of NR remain unclear to date, which restricts the practical application of the enzymatic coagulation process for the processing of NR. In this work, peptidase-treated raw NR was subjected to accelerated storage conditions. It was observed that during the storage process, dynamic imine bonds (–C= N –) were formed through condensation reactions between the –NH 2 groups generated from peptidase-hydrolyzed proteins and the –CHO groups from the NR backbone. The formation of these dynamic imine bonds did not significantly deteriorate the processing characteristics or vulcanization performance of the peptidase-treated NR. Moreover, the tensile strength of vulcanized NR increased from 19.2 to 26.1 MPa, and its toughness increased from 30.5 to 41.3 J/cm 2 , demonstrating an obvious self-strengthening induced by storage. Mechanistic studies revealed that dynamic imine bonds not only dissipate energy efficiently but also promote strain-induced crystallization (SIC), thus endowing the resulting vulcanized NR with improved strength and toughness. This work presents a comprehensive study of the structure–performance relationships of peptidase-treated NR during storage.

By using plastic wastes as starting materials, a waste-to-resource strategy was proposed to fabricate functionalized aerogel membrane with remarkable structural stability and wetting selectivity for continuous emulsion separation. The interlaced nanofibers used to make the hybrid aerogel membrane resulted in its exceptional wettability, high porosity, and micropore size. Contact angle measurements reveal that the hybrid aerogel membrane exhibits distinctive wettability characteristics, closely resembling those found on inverse beetle elytra surfaces. In gravity-driven oil/water separation tests, the hybrid aerogel membrane achieved an emulsion separation efficiency of 99.0%. The peculiar properties of the porous aerogel membrane, due to its 3D porous structure and rough surface, have greatly enhanced emulsion separation. Moreover, after 15 cycles, the aerogel membrane retains a separation efficiency of over 98.0%, demonstrating its exceptional recyclability. Overall, this work opens a new avenue to fabricate porous aramid nanofiber hybrid aerogel membrane with super hydrophilic character from waste plastic for stabilized emulsion separation, with high potential for practical applications in oily wastewater treatment and waste plastic recycling.

To address the synergistic removal of Congo Red (CR) and hexavalent chromium (Cr(VI)) from industrial wastewater, this study proposed an “electrospinning-surface modification” strategy. Using poly(vinyl alcohol-co-ethylene) (PVA-co-PE) as the substrate, a dual-functional composite nanofibrous membrane adsorbent (PVA-co-PE/chitosan (CS)/polydopamine (PDA)) was constructed via CS grafting and PDA coating. The structural and physicochemical properties of the PVA-co-PE/CS/PDA NF membranes were characterized by elemental mapping, spectroscopic analyses, and morphological observation, while batch experiments were conducted to investigate the adsorption behavior and key influencing factors. Results showed that the composite membrane exhibited maximum adsorption capacities of 716.9 mg/g for CR and 264.4 mg/g for Cr(VI), with the adsorption process conforming to the Langmuir monolayer adsorption model and pseudo-second-order kinetic model (dominated by chemical adsorption). After four adsorption–desorption cycles, the membrane retained adsorption capacities of 609.3 mg/g for CR and 224.5 mg/g for Cr(VI), demonstrating excellent cyclic stability. With advantages of simple preparation, strong recyclability, and negligible secondary pollution, the proposed composite membrane serves as a novel, efficient adsorbent for the synergistic advanced treatment of organic dyes and heavy metal ions in complex industrial and holds substantial engineering application value.

It is well-known that a lower wear rate, favorable mechanical properties, and limited inflammatory response are critical factors in determining the long-term service of orthopedic implants. In this study, we prepare TaB 2 /PEEK coatings by electrophoretic deposition (EPD) of borated tantalum (TaB 2 ) and polyether-ether-ketone (PEEK) particles on a pure titanium plate (TA2). Nanoindenter, reciprocating ball-on-disc tester, and in vitro biological experiments were used to investigate the effects of TaB 2 particles on the mechanical properties, tribological properties, and biological properties of composite coatings. The results demonstrate that a small amount of TaB 2 particles were equally dispersed in the PEEK matrix, and the mechanical properties are improved, resulting in better tribological properties of the coating. In particular, the wear rate of P-TB-3 coating in the simulated body fluid (SBF) was 72% lower than that of the PEEK coating, with a friction coefficient (COF) of 0.164 and a wear rate of 1.45 × 10 −6 mm 3 ·N −1 m −1 , respectively. Furthermore, the P-TB-3 surface boosted Raw264.7 macrophage adherence and proliferation, with a potential to promote Raw264.7 macrophage transition to the M2 phenotype. These results suggest that the P-TB-3 coating prepared by EPD is considered as a promising implant replacement material.

With the growing demand for sustainable and biodegradable adhesives, castor oil has gained attention as a promising bio-based raw material due to its hydroxyl functionality, low toxicity, and environmental benefits. In this study, a solvent-free pressure-sensitive adhesive (CO-PSA) with a high castor oil content (55 wt%) was synthesized via controlled functionalization of castor oil (trifunctional to difunctional) and polymerization with isophorone diisocyanate (IPDI). FTIR confirmed the target chemical structure of CO-PSA by comparing the structures of the starting material, intermediates, and final product. The optimal CO-PSA formulation (CO-PSA-3) exhibited outstanding adhesive performance: initial tack for an 11# steel ball, 180° peel adhesion strength of 12.26 N/25 mm, and static shear holding power of 25 h. Wettability tests confirmed good surface interaction (water contact angle < 80° for all formulations), ensuring effective substrate bonding. Thermal analysis (DSC/TGA) indicated good thermal stability (initial thermal degradation temperature: 266°C) and flexibility at low temperatures (glass transition range: −70°C to −32°C). Degradation studies showed that CO-PSA undergoes complete alkaline hydrolysis within 2 h, forming nanoscale degradation products (~90 nm in diameter). The high–castor-oil (55 wt%), solvent-free, and degradable CO-PSA formulation developed in this study can serve as an environmentally friendly alternative to petroleum-derived adhesives, advancing sustainable adhesive technologies for the packaging industry and related sectors.
