To realize this objective in copper (Cu)/polyvinylidene fluoride (PVDF) nanocomposites, the Cu nanoparticles were initially coated with titanium oxide (TiO2) and magnesium oxide (MgO), respectively, followed by compounding with PVDF to investigate the double‑shell’ effect on dielectric performance. The results demonstrate that the Cu@TiO2@MgO/PVDF displays elevated ε and Eb, along with lower loss dissipation (tanδ) when compared to Cu/PVDF. The increased ε is attributed to the enhancement of both high-frequency intra‑particle and low‑frequency inter‑particle polarizations resulting from the double-interlayer. The TiO2@MgO not only prevents direct contact between Cu nanoparticles but also creates charge traps, reducing the tanδ and leakage conductivity. The double shell mitigates interfacial dielectric parameter mismatch, thereby enhancing the Eb. Simulations and theoretical calculations reveal the multiple polarization mechanisms and the regulated charge transport behavior in the Cu@TiO2@MgO/PVDF. The conductive core-insulating double-shell strategy provides an insightful view on promoting multiple polarizations and suppressing charge migration in percolating polymer nanocomposites.

One of the 4D printing techniques is utilizing chemical potential gradient where uniform swelling of gels with a structural gradient leads to preprogrammed shapes. This work investigates the inverse effect: swelling a uniform structure by a diffusion gradient. First, the recently observed temporal shape changes of liquid crystal elastomer (LCE) films based on diffusion of low molecular weight liquid crystal drops into the LCE are simulated, showing excellent agreement with the experiments. Second, ways of locking the desired LCE shape by UV-induced polymerization or by crystallization of a reactive low molecular weight LC additive are investigated. It is shown that the crystallization of the diffusing low molecular weight LC provides the fastest and most complete locking of the shape. It is envisioned that using the gradient of the chemical potential either by pre-patterning the director structure of the LCE film or by appropriate spatial distribution of LC droplets, any complex shapes of LC rubbers can be engineered. This may provide a new and effective way of shaping rubbers for applications in various fields, such as sealants, soft robotics and bioimplants.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":"47 21","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/marc.70418","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This Perspective argues that a key bottleneck for these materials is not model architecture but a polymer-specific gap: macroscopic, processing-dependent properties and slow validation timescales. I distinguish chemistry-dominated, condition-dependent, and process-history-dependent properties, and develop two contrasting cases: sustainable thermoplastics, governed by melt flow and thermal history, and supramolecular hydrogels, governed by aqueous self-assembly.

The contribution is not the closed loop, which is well established, but the claim that, for non-dilute melts, concentrated solutions, and assembled soft matter, and for properties whose validation runs to months or years, polymer process physics and slow-property validation are among its principal frontiers.

In this study, we present a high-performance, chemically recyclable epoxy thermoset based on 1,3,5-triazine, demonstrating significant advancements in material recyclability and application potential. Utilizing liquid precursors, that is a trifunctional epoxy monomer (TOMTA) and a strategically selected secondary aromatic diamine hardener (MBMA), a cross-linked network with a well-defined architecture was produced under bulk conditions. The resulting thermoset exhibited exceptional thermal and mechanical properties as evidenced by a high glass transition temperature (Tg = 105°C), thermal stability (Td5% = 256°C), a Young's modulus of 3.0 GPa, and a tensile strength of 96 MPa, placing the material in the same performance range of conventional epoxy resins. Driven by an optimized binary K2CO3/TBD catalytic system in ethanol, the network underwent depolymerization enabled by a nucleophilic aromatic substitution reaction (SNAr), yielding the well-defined building blocks TETA and the tetraol BDHPPM in 70% and 65%, respectively, via straightforward liquid-liquid extraction. Re-crosslinking these recovered building blocks regenerated the network, preserving nearly identical properties across multiple recycling cycles. The system was further applied as a debondable coating for glass. This 1,3,5-triazine-based network utilizing SNAr chemistry provides a robust route to high-performance, recyclable epoxy thermosets.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":"47 21","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/marc.70422","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twisted and coiled polymer (TCP) artificial muscles, typically fabricated from fibrous materials, offer high power density and large stroke; however, their reliance on elevated operating temperatures (>80°C) for high performance limits their use in temperature-sensitive environments. Here, we report a thermoresponsive gel-yarn composite actuator that enables actuation at reduced temperatures within TCP-based systems. Twisted polyester yarns were functionalized with a biocompatible thermosensitive hydrogel, poly(MAA-co-OEGMA), forming a fiber-gel composite architecture. Temperature-induced swelling and deswelling of the hydrogel in cold and hot water, respectively, generated internal stresses within the yarn, which drive untwisting of the coiled structure and result in lengthwise actuation. The effect of ionic crosslinking was systematically investigated by varying FeCl3 concentration, with 1 M identified as the optimal condition balancing structural stiffness and actuation performance. The composite actuators exhibit isotonic free strains of up to 39% when cycled between room temperature and 50°C and work densities of up to 8.8 × 10−3 J g−1, with reversible and repeatable actuation behavior. Compared to conventional TCP systems, which typically operate at substantially higher temperatures, the present system achieves similar deformation but within a lower and more practical thermal range. These findings suggest that fiber-gel composite architectures provide a viable route for tuning actuation behavior in TCP systems while maintaining compatibility with temperature-sensitive applications.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":"47 21","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/marc.70432","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148975191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, high-molecular-weight linear poly(phenylene oxide) (PPO) suffers from poor melt flowability, while molecular-weight reduction can compromise network rigidity. In this work, a four-arm star-shaped vinyl-terminated PPO precursor (sPPO-V) was synthesized using tetrafunctional initiator TDPE. Molecular-weight-matched high-molecular-weight linear PPO (HMW-PPO) was prepared as a control to evaluate the effect of molecular architecture. SEC, 1H NMR, and FT-IR analyses confirmed the successful synthesis of the star-shaped precursor. Rheological measurements demonstrated that sPPO exhibited reduced melt viscosity compared with linear PPO controls, including HMW-PPO with comparable molecular weight. After curing, sPPO-V showed an increased glass-transition temperature of 220°C, together with improved dielectric properties (Dk = 2.50, Df = 2.11 × 10-3 at 1 GHz), thermal stability (Td5 = 330°C), and moisture resistance (water contact angle of 98.3° and water uptake of 0.18% after 72 h). The enhanced performance was attributed to the multi-arm architecture-induced topological constraints and reduced molecular packing efficiency. This work demonstrates that molecular architecture engineering is an effective strategy for balancing processability, thermal rigidity, dielectric performance, and moisture resistance in PPO-based thermosetting resins.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149316501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe a position-resolved fluorescence polarization strategy to map apparent segmental rigidity within block copolymer micelles. By covalently installing the same dansyl fluorophore at defined positions along an amphiphilic block copolymer chain, we selectively label the hydrophobic core, core-corona interface, and oligo(ethylene glycol) (OEG)-rich corona of the micelles. The resulting fluorescence polarization profiles reveal a pronounced core-to-corona apparent rigidity gradient in water, distinguish block-segregated micelles from compositionally matched random copolymer assemblies, and report micellar responses to temperature, cosolvent, and salt. This method further enables structural interrogation of polymer micelles in biologically relevant media, revealing the unexpected finding that biological serum exerts opposing effects on apparent chain rigidity in the micellar core and corona. Together, these results establish position-resolved fluorescence polarization as a practical platform for linking block copolymer structure, self-assembly, local chain dynamics, and biological stability, opening new opportunities to rationally design micelles with environment-responsive mechanical properties.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149293487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acrylate-based photosensitive resins are widely employed in such processes owing to their fast-curing speed and high printing precision. However, acrylate-based systems still present considerable challenges for 3D-printed circuits, mainly due to inherent drawbacks including inadequate toughness, low tensile strength, and high dielectric loss. Herein, polyphenylene ether (PPO)-modified acrylate photosensitive resins are designed and prepared to tackle these issues. The introduction of PPO endows the inks with pronounced shear-thinning behavior and rapid thixotropic recovery, thus facilitating smooth extrusion and high-fidelity direct ink writing. The optimized formulations exhibit remarkably enhanced tensile properties with tensile strength increased from 28 to 74 MPa, while elongation at break rises from 2.7% to 8.8%. The dielectric constant and loss decrease from 3.06 to 2.53 and 0.016 to 0.012 at 5 GHz, respectively, accompanied by reduced water absorption from 1.74% to 1.39%.
