The mean-field tube model has long served as the standard paradigm for describing the many-body entanglement problem as the motion of a single chain in a static field; it faces intrinsic limitations when spatial correlations, fluctuations, and complex topological rearrangements are addressed. To overcome these limitations, “multichain” approaches—specifically, the primitive chain network and multichain slip-spring models—were developed. These simulations explicitly resolve the force balance and topological coupling between multiple chains in three-dimensional space. This review covers the primitive chain network model, which emphasizes real-space force balance, and the multichain slip-spring model, which is derived from a well-defined free energy functional. Linear and nonlinear rheology predictions are discussed, along with molecular mechanisms such as constraint release and stretch/orientation-induced reductions in friction. Extensions to branched polymers, wall-slip phenomena, and network polymers are also mentioned. This review summarizes efforts to develop coarse-grained multichain models for entangled polymers. The studies aim to bridge an important gap between the standard bead-spring model and the tube model. The primitive chain network model is a multi-chain version of the tube-type description, whereas the multichain slip-spring model is a multichain entangled Rouse model. Both models reproduce entangled polymer dynamics at a lower computational cost than bead-spring simulations and straightforwardly account for complex multi-chain correlations that tube models capture via the mean-field approach.","PeriodicalId":20302,"journal":{"name":"Polymer Journal","volume":"58 10","pages":"1243-1255"},"PeriodicalIF":3.1,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41428-026-01206-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148928136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have developed a new class of proton-conductive materials using the liquid-crystalline self-assembly of specifically designed amphiphilic zwitterions. The combination of amphiphilic zwitterions and certain acids leads to the formation of bicontinuous cubic liquid-crystalline phases with gyroid nanostructures. These materials form a specific gyroid minimal surface where sulfonate groups are densely aligned. High proton conductivity is found for these liquid-crystalline materials under humidified conditions. The surface proton hopping conduction (SPHC) mechanism, which involves protons hopping between neighboring sulfonate groups via bound water molecules, acts as the principal proton conduction mechanism in the liquid-crystalline materials with the specific surface, whereas the Grotthuss mechanism is the dominant proton conduction mechanism in conventional proton-conductive polymer membranes. In this Focus Review, we summarize our molecular design for creating SPHC-dependent proton-conductive materials and the potential utility and functions of these materials. Our recent studies on the polymerization of amphiphilic zwitterions to afford gyroid nanostructured polymer films s are reviewed. In the first part of this article, our molecular design of self-organizing amphiphilic zwitterions is described. The second part of this article summarizes the proton conduction mechanism in the gyroid nanostructured polymer films.

Previous studies have reported good biocompatibility and reduced accelerated blood clearance (ABC) in PG-grafted systems. However, quantitative benchmarks describing linPG chain dimensions and solvent quality in water remain limited. Here, we synthesize linPG by anionic ring-opening polymerization and quantify its structural and thermodynamic properties in water using small-angle neutron scattering (SANS). Zimm analysis yields the radius of gyration at infinite dilution (Rg,0) and second virial coefficient (A2) for linPG between 25 and 60 °C across a range of molecular weights, enabling direct comparison with poly(ethylene glycol) (PEG). The A2 values of linPG are positive throughout this temperature window, which is consistent with good solvent conditions, whereas A2 and Rg,0 decrease slightly with increasing temperature, indicating reduced polymer–solvent affinity. Compared with PEG at comparable degrees of polymerization, linPG has smaller Rg,0 values while maintaining similar A2 magnitudes, which is consistent with a less expanded yet still swollen coil conformation. These results establish quantitative benchmarks for linPG in aqueous solution and provide design-relevant parameters for PG-based hydrophilic coronas. Quantitative small-angle neutron scattering (SANS) and Zimm analysis reveal that linear poly(glycerol) (linPG) exhibits smaller coil dimensions (Rg,0) and a lower scaling exponents (v) than poly(ethylene glycol) (PEG), indicating a less expanded chain conformation in water. linPG maintains positive second virial coefficients (A2) from 25 to 60 °C, and the estimated theta temperature (Tθ) is higher than PEG, consistent with favorable polymer‒solvent interactions under aqueous conditions.","PeriodicalId":20302,"journal":{"name":"Polymer Journal","volume":"58 9","pages":"1049-1058"},"PeriodicalIF":3.1,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41428-026-01207-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This copolymer is biodegradable, biocompatible, and temperature responsive. Viscoelasticity measurements revealed that the aqueous solution of the PLGA-PEG-PLGA triblock copolymer began to gel at approximately 37 °C and was maintained at approximately 43 °C. Compared with the GGsTop® aqueous solution, the incorporation of GGsTop® into the gel markedly suppressed its release from 15 min after the start of testing, demonstrating the sustained release of GGsTop®. In a mouse model of chemotherapy-induced stomatitis, compared with the GGsTop aqueous solution, the topical application of the GGsTop®-loaded gel formulation significantly reduced the lesion area and shortened the treatment period. Additionally, a significant decrease in the levels of reduced glutathione, an indicator of oxidative stress, was observed. These results suggest that the prepared gel formulation enhances the oral retention of GGsTop® and improves its therapeutic efficacy. On the basis of the above findings, the GGsTop®-loaded gel formulation was shown to be effective against stomatitis, a side effect of cancer treatment. Thermoresponsive PLGA–PEG–PLGA hydrogel undergoes a sol-to-gel transition at body temperature, forming a micelle-based three-dimensional network that enables sustained local delivery of GGsTop®. This system improves drug retention at the oral mucosa and provides prolonged release, leading to suppression of oxidative stress and significant alleviation of chemotherapy-induced oral mucositis. Furthermore, the sol-to-gel transition reduces administration burden, contributing to improved treatment adherence and overall quality of life.","PeriodicalId":20302,"journal":{"name":"Polymer Journal","volume":"58 10","pages":"1281-1291"},"PeriodicalIF":3.1,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41428-026-01167-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148928142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we examine how multiscale orientational order in dip-coated liquid-crystalline films of filamentous M13 bacteriophages is related to lateral heat spreading. Films were prepared on glass, polyimide, and poly(L-lysine)-coated glass with varying withdrawal speed (10–80 µm min−1) and solution pH (5, 7, or 11). The orientational order was quantified from 30 × 30 µm2 atomic force microscopy height images using two-dimensional Fourier analysis to obtain tile-averaged and whole-image order parameters. For polyimide-supported films at pH 7, the tile-averaged parameter (S) increased from 0.318 to 0.544 as the withdrawal speed increased from 10 to 80 µm min−1. In-plane thermal conductivity along the coating direction was measured for polyimide-supported films by scanning laser-heating photothermal radiometry and extracted using differential two-layer analysis, yielding 3.1 ± 1.1, 4.2 ± 2.0, and 9.3 ± 1.2 W m−1 K−1 at 10, 50, and 80 µm min−1, respectively. These results support an initial structure–property correlation between enhanced alignment and increased in-plane thermal transport in supported virus films, and they highlight the need for nonequivalent metrics to describe mesoscale alignment. Controlled withdrawal during dip-coating directs liquid-crystalline assembly of filamentous M13 bacteriophages into uniaxial bundle textures. 2D-FFT analysis of AFM images quantifies multiscale orientational order using tile-averaged and whole-image metrics. For polyimide-supported films, higher orientational order correlates with higher in-plane thermal conductivity along the coating direction, extracted from scanning laser-heating photothermal radiometry using a differential two-layer model.","PeriodicalId":20302,"journal":{"name":"Polymer Journal","volume":"58 10","pages":"1329-1336"},"PeriodicalIF":3.1,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41428-026-01202-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148928184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrogels had a diameter of ~3 mm and a moisture content of 79–70 wt%. Scanning electron microscopy revealed surface internetwork distances of 20 μm for the hydrogel without β-CyD and 20 μm (18–21 μmol g−1), 25 μm (34 μmol g−1), and 30 μm (36–55 μmol g−1) for the PVA-mix-βCyD/HDI hydrogels. In contrast to that of the PVA-co-βCyD hydrogels, where β-CyD was uniformly dispersed, network spacing increased proportionally with increasing β-CyD content. PhOH-degrading bacteria were immobilized as biocatalysts and tested in model wastewater (500 mg L−1 PhOH). The degradation rate of the β-CyD-containing biocatalyst was approximately twice that of the β-CyD-free biocatalyst, with saturation above 20 μmol g−1. The β-CyD content at saturation was lower for the PVA-mix-βCyD/HDI biocatalyst than for the PVA-co-βCyD biocatalyst. Furthermore, fluorescence in situ hybridization confirmed uniform bacterial dispersion throughout the inner layer of the gel, with the bacterial abundance increasing as the β-CyD content increased.

This trend is opposite to that observed for the homogeneously dispersed PVA-co-βCyD hydrogel in which the β-CyD component was introduced via co-formalization cross-linking reaction. PhOH-degrading bacteria were immobilized as biocatalysts. The PhOH-degradation rate increased with increasing β-CyD content In PVA-mix-βCyD/HDI, it was confirmed by fluorescence microscopic observation by FISH that a large number of bacteria were dispersed throughout the inner gel layer, and the bacterial population increased with higher β-CyD content.

The incorporation of the strongly electron-deficient PyPy unit deepens the HOMO level, resulting in high open-circuit voltages of up to 0.93 and 1.21 V when combined with the nonfullerene acceptors IT-4F and IO-4F, respectively.

In this work, three-dimensional (3D) macroporous composite foams composed of multiwalled carbon nanotubes (MWCNTs) and poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT: PSS) were fabricated via freeze-drying. The resulting sponges achieve outstanding performance in terms of solar-driven interfacial water evaporation (SIWE), efficient adsorption of organic dyes, and robust anti-fouling properties. The light absorption capacity and surface hydrophilicity of these sponges can be precisely controlled by altering their chemical composition. The incorporation of MWCNTs and hydrophilic polyethylene oxide into the 3D sponge framework significantly improves the evaporation performance owing to improved broadband light absorption and facilitated water transport. Moreover, the MWCNT/PEDOT: PSS sponges have high adsorption capacities for methylene blue and methyl orange, enabling simultaneous desalination and contaminant removal.
