In this study, methyl tetrahydrophthalic anhydride (MTHPA) and tris(dimethylaminomethyl)phenol (DMP‐30) are used as the curing agent and catalyst, respectively, while amino‐terminated liquid nitrile rubber (ATBN) is served as the toughening agent. In parallel, an interpenetrating polymer network (IPN) derived from NCO‐terminated oligomers is introduced to synergistically enhance ILSS, compressive strength, and flexural strength. DMP‐30 regulates the curing mechanism of epoxy resin by controlling the reaction between hydroxyl and epoxy groups, thereby tuning the crosslinking density in the EP/MTHPA/DMP‐30 matrix. ATBN improves the toughness of epoxy resin through a chemical reaction between its amino groups and the epoxy matrix. Furthermore, NCO‐terminated oligomers are incorporated into the ATBN‐toughened EP/MTHPA/DMP‐30 matrix, forming an IPN‐modified composite via selective reaction between NCO groups and hydroxyl groups in the matrix.

However, due to the differing affinities of the filler toward each rubber phase, it tends to preferentially disperse in one phase, leading to partial inhomogeneity of filler distribution between the two phases and ultimately compromising the overall performance of the nanocomposite. In this work, epoxidized NR (ENR) and epoxidized BR (EBR) with different epoxide degrees are synthesized through in situ epoxidation, and then blended with TESPT‐modified SiO 2 to prepare the corresponding nanocomposites ENR/EBR‐ x /SiO 2 . With the epoxide degree of EBR increasing, the filler‐rubber interaction is enhanced, leading to improved SiO 2 dispersion and phase distribution within the rubber matrix, as well as enhanced compatibility between the ENR and EBR phases. Compared with the conventional NR/BR/SiO 2 system, the prepared ENR/EBR‐15/SiO 2 nanocomposite achieves a more balanced “magic triangle” of tire tread performance, including a 94% improvement in wet‐skid resistance, an 18.8% reduction in rolling resistance, and a 6% reduction in abrasion volume. Furthermore, the tensile strength is enhanced by 11.5%, and the dynamic heat build‐up is reduced by 3.8°C.

In this work, a nacre‐inspired strategy was proposed by integrating molybdenum disulfide (MoS 2 ) nanosheets with a metal‐phenolic network (MPN) to construct a hierarchical “brick‐mortar” interphase. MoS 2 nanosheets were in situ grown on the carbon fiber surface as rigid bricks, which not only increased surface roughness and provided abundant anchoring sites but also facilitated crack deflection. Subsequently, a flexible MPN layer was deposited as the mortar, introducing strong adhesion and energy‐dissipation capacity through hydrogen bonding, π–π interactions, and Fe 3+ ‐tannic acid coordination. Mechanical tests demonstrated that this “brick‐mortar” interphase significantly enhanced composite performance. Compared with pristine CF/EP composites, the interlaminar shear strength, flexural strength, and transverse tensile strength were improved by 19.2%, 82.1%, and 32.6%, respectively.

However, the presence of cured urea‐formaldehyde resin within the fibers adversely affects the mechanical properties of the recycled fiberboards. This study proposes a novel approach that simultaneously utilizes cured adhesive and intrinsic lignin to produce high‐performance recycled fiberboard. Under acidic conditions, cured urea‐formaldehyde resin partially hydrolyzes, meanwhile a portion of lignin is oxidatively depolymerized by sodium chlorite. During hot pressing, activated lignin softens, penetrates, and undergoes condensation, while activated resin participates in polycondensation. The recycled fiberboards exhibit excellent mechanical properties, which may be attributed to fiber entanglements within the board and the formation of new hydrogen and chemical bonds between lignin‐fibers, and UF‐fibers. The boards achieve an internal bonding strength of ~1.98 MPa, a modulus of rupture (MOR) of ~65.6 MPa, and a modulus of elasticity (MOE) of ~6678 MPa. This simple co‐utilization strategy reduces petrochemical adhesive use and enhances material recyclability, offering a promising route for high‐performance, sustainable recycled fiberboards. Such a closed‐loop recycling strategy may guide the future recycling of wood‐based composites.","PeriodicalId":510403,"journal":{"name":"Polymer Composites","volume":"47 10","pages":"8976-8989"},"PeriodicalIF":0.0,"publicationDate":"2025-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental results showed that at Al 2 O 3 and CNT loadings of 48 and 2 wt%, respectively, the thermal conductivity of the composites reached 0.85 W m −1 K −1 , representing a 240% improvement over neat PA6 and superior performance compared to melt‐blended samples with identical compositions. This performance enhancement was attributed to the ability of reactive blending to achieve uniform dispersion of Al 2 O 3 and good dispersion of CNTs even at high filler loadings, effectively suppressing filler agglomeration and defect formation while constructing more continuous thermal conduction networks. Parallel–series (P‐S) model analysis verified the superior thermal network connectivity of reactively blended samples, and LED heat dissipation tests demonstrated that the material could reduce LED surface temperature by 18.6°C. The reactive blending approach significantly enhanced the tribological properties of PA6/Al 2 O 3 composites compared to the traditional melt blending method. The rbPA6/Al 2 O 3 /2CNT composite exhibited superior performance with a coefficient of friction of 0.35, representing a 58.8% reduction compared to the melt‐blended mbPA6/Al 2 O 3 . Most impressively, the wear rate was reduced to 7 × 10 −5 mm 3 /(N m), a remarkable 70.4% reduction compared to the melt‐blended mbPA6/Al 2 O 3 . The excellent thermal conductivity facilitated rapid dissipation of frictional heat, further enhancing the wear resistance of the material.

SPPS was used to size CFs surface treated with Meldrum's acid, and the surface elemental composition of SPPS‐sized CF (SPPS‐CF) at various concentrations was analyzed using X‐ray photoelectron spectroscopy (XPS). The results revealed that, compared to the untreated carbon fiber/PPS (U‐CF/PPS) composites, the interlaminar shear strength (ILSS) of SPPS‐CF/PPS composites increased by 158%. This marked improvement can be ascribed to two primary factors: (i) the increase in surface energy of the CFs due to the incorporation of activated carbon fiber (A‐CF) and the polar groups in SPPS, which enhanced the wettability between the fiber and the resin—as evidenced by a rise in total surface energy from 28.5 mJ/m 2 for D‐CF to 39.3 mJ/m 2 for SPPS‐CF (0.4%) (an increase of 42%), accompanied by a decrease in the dynamic contact angle with deionized water from 79.3° to 61.8°; (ii) the establishment of excellent compatibility between the SPPS sizing agent and the PPS matrix due to their similar solubility.","PeriodicalId":510403,"journal":{"name":"Polymer Composites","volume":"47 10","pages":"8950-8962"},"PeriodicalIF":0.0,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pc.70731","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
