Linear (TPU) and partially crosslinked TPUs (xTPUs) were synthesized by a two-step prepolymer method using polycaprolactone triol (PCLT) as a multifunctional SS crosslinker, with triol hydroxyl contributions of 0, 2.5, 5, and 10 mol%. The formulations were designed to maintain nearly constant hard segment (HS) content, chemistry, and comparable HS spacing, enabling the isolated evaluation of crosslinking effects. Relative to the linear TPU, the xTPUs exhibited progressively improved high-temperature thermomechanical stability, including up to 25% higher rubbery modulus, 30°C delayed onset of terminal flow, 55% lower creep deformation, 90% lower creep rate, and 14% improved elastic recovery at 125°C. FTIR, DSC, and SAXS analysis showed that the introduced crosslinker content was low enough to preserve thermoplastic character, while increasingly restricting annealing-induced phase separation and hard domain development. Reprocessing experiments demonstrated that controlled crosslinking significantly improved retention of high-temperature creep resistance after repeated melt processing, with xTPU-10 showing the best durability. Overall, controlled SS crosslinking provides an effective route to balance enhanced high-temperature performance, melt reprocessability, and improved sustainability in TPU systems.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction of paper tape as a substrate material is proposed to increase print bed adhesion. Isothermal digital scanning calorimetry (DSC) analysis shows that higher holding temperatures delay crystallization, thereby reducing shrinkage during processing. The crystallization kinetics is observed by measuring the peak crystallization time, which increases from 3.6 s at 135 °C holding temperature to 15.6 s at 145 °C holding temperature. The principal processing parameters, such as print bed temperature and nozzle diameter, were systematically varied to assess their influence on both mechanical and tribological performance of the POM specimens. A nozzle diameter of 0.4 mm achieved a tensile strength of 43 MPa, compared with 56 MPa for injection-moulded POM. Conversely, a large nozzle diameter of 0.8 mm enhances wear resistance by six-fold compared to a smaller nozzle diameter of 0.4 mm. An optimum print bed temperature of 140 °C enhanced both mechanical and tribological performance. These findings offer a comprehensive framework for optimizing FLM process parameters to enable functional use of POM based components in engineering applications.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70290","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, poor interfacial adhesion and phase separation must be taken into account due to inherent incompatibility between different phases in these systems. To overcome this problem, various compatibilization strategies have been developed. This review highlights recent developments and emerging compatibilization strategies in polymer blends and polymer nanocomposites. In first section, classical methods including use of block, branched, and statistical copolymers, addition of low molecular weight materials, exchange reactions, selective cross-linking agents, and use of fillers including Janus nanoparticles are discussed. Special focus is placed on reactive polymers containing maleic anhydride, carboxylic, amine, and hydroxyl/epoxy groups as well as polymers capable of forming ionic bonds. Importance of compatibilization in polymer nanocomposites is then discussed, and physical methods (such as surface treatment and encapsulation techniques) are compared with chemical methods (such as use of coupling agents and graft polymerization techniques). Conclusively, compatibilization not only increases phase stability and improves interfacial adhesion, but also significantly improves mechanical, thermal, and barrier properties. The advantages, limitations, and future prospects of compatibilization techniques for development of new generation advanced polymer materials are also discussed.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70288","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, four TPMS geometries (Schwarz, Gyroid, Diamond, and Split-P) and one solid cylindrical geometry were produced via Digital Light Processing (DLP) and evaluated comparatively. Electrical measurements revealed that conductivity is largely dependent on the internal architecture. The solid cylinder exhibited the highest value (2.85 × 10−4 S/cm), followed by Gyroid (2.80 × 10−4 S/cm). The Diamond structure showed the lowest conductivity (1.53 × 10−4 S/cm). Eight-week in vitro degradation tests revealed accelerated mass loss in porous TPMS structures; the Gyroid exhibited the highest degradation rate (96.16% remaining mass), while the Schwarz structure showed the highest mass retention rate (98.62%) among the TPMS designs. Compression tests confirmed that all TPMS-based channels maintained sufficient mechanical integrity under physiologically relevant loads. The findings demonstrate that the TPMS architecture provides an effective design parameter for customizing the electrical, mechanical, and degradation behavior of NGCs without altering the base material, suggesting potential for nerve regeneration applications.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70281","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Direct-ink-writing (DIW) is a powerful method to achieve freeform manufacturing; however, formulating ionogels with both DIW printability and mechanical toughness has been a challenge. Here, we present a one-pot, 3D-printable ionogel that provides high ionic conductivity, DIW printability, and mechanical toughness. The ionogels incorporate a copolymer network made of acrylamide (AAm) and 2-hydroxyethyl methacrylate (HEMA) with a tricomponent solution mixture of water and the 1-butyl-3-methylimidazolium tetrafluoroborate-based based ionic liquids with two anions, [BMIM]BF4 and [BMIM]Cl. Carbopol 940 microgel, a rheology modifier, enables printability. The composition ratio between the solution components impacts ionic conductivity and mechanical properties, which are correlated with the interactions between the anionic and cationic species in the solvent. At optimized solvent compositions, electrochemical impedance spectroscopy shows that the ionogel has an ionic conductivity of up to 4.91 mS cm−1 and is capable of uniaxial stretching up to 400% while supporting a 750 g load with thin thread samples with cross sectional areas of ∼5 mm2. The addition of Carbopol 940 results in a shear-thinning behavior that allows printability. Potential applications include flexible/wearable electronics, energy storage devices, and soft actuators.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70291","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trauma presents challenges for neurosurgeons, causing complications such as cerebrospinal fluid leakage, infection, and brain herniation. Several dural substitutes are available clinically; however, many fail to fully replicate the native dura mater's multilayered architecture, mechanical strength, and functional properties such as cerebral tissue adhesion prevention and effective leakage control. In this study, a tri-layered porous fibrous composite matrix was fabricated to mimic the structural and functional characteristics of native dura mater. The composite was developed using silk fibroin, gelatin, polycaprolactone (PCL), carboxymethyl cellulose (CMC), and biphasic calcium phosphate (BCP). The outer layer (SFP-BCP) consisted of silk fibroin, PCL fibers, and BCP to replicate the lamellar cranial side. The middle layer (GP) was composed of gelatin and fibers, and the inner layer contained fibers with CMCs to simulate the cerebral side. The fabricated trilayered structure was successful in replicating the native multilayered structure of the dura mater as observed through SEM analysis, with a maximum tensile strength of 1.41 ± 0.179 MPa. The optimized trilayered scaffold exhibited controlled swelling, effective antileakage properties, and supported the growth of MG-63 and L929 cells, indicating its potential as a dural biosubstitute.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70279","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural characterization confirmed the successful formation of the target compound. The incorporation of 1.5 wt% antioxidant significantly enhanced the thermal and oxidative stability of PP, resulting in a ∼65-fold increase in oxidation induction time (OIT) and improved retention of mechanical properties (∼79%) after thermo-oxidative aging. Notably, the modified PP exhibited markedly reduced UV transmittance, decreasing from 62.96% to 6.26% at 294 nm while maintaining high visible transparency, indicating strong UV-shielding capability and potential photostabilization effects. These improvements are attributed to the synergistic radical-scavenging and hydroperoxide-decomposing functionalities, combined with reduced migration arising from the structurally rigid molecular architecture. This work provides an effective strategy for developing multifunctional antioxidants for durable polymer stabilization.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 7","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70292","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The melt processing of TPS is, however, challenging due to its moisture sensitivity and rapid aging. This study investigates the development of TPS/PBSA blends without compatibilizers, comparing a conventional two-step processing method with a one-step approach combining starch plasticization and its blending with PBSA. The one-step process exhibits higher stability, making it a promising candidate for industrial applications due to its reduced energy consumption and production costs.
