In this approach, polyols were used both as crosslinking components and physically coating agents of cellulose nanocrystals (CNC) and through a freeze-drying method with water, CNC dispersion inside PLA was enhanced. Meanwhile, during the establishment of DCN inside PLA, the coated CNC were subsequently connected to the DCN to enhance reinforcement. The freeze-dried, glycerol-coated CNC exhibited significantly improved dispersion, indicated via an average distributed length of approximately 400 nm, which is much smaller than the several-micrometer length of untreated CNC particles. This enhanced dispersion and reinforcement further notably reinforced melt strength, mechanical stiffness and thermal resistance of the PLA/CNC composites. Much more pronounced strain hardening behavior, a ∼20% increase in storage modulus and 3.7 °C increase in Vicat softening temperature were observed compared with the neat PLA matrix. As a practical outcome, the CNC-reinforced DCN systems demonstrated excellent foamability, achieving a 25-fold foam expansion, attributed to CNC's role as a foaming nucleating agent. Last but not least, the entire process is recyclable, re-processable, organic-solvent-free and suitable for continuous melt extrusion. Based on these results, this method could potentially be applied to transform similar polyester-based polymer wastes into a composite DCN form, offering improved mechanical and melt-strengthening properties, without sacrificing the original processability, thus realizing upcycling of polyesters.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":"6323-6335"},"PeriodicalIF":2.9,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148962694","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}

However, the reaction pathways responsible for IL-initiated curing remain underexplored, particularly the effect of cation-induced pathways for imidazolium-based ILs. Here, the curing behavior of epoxy resins initiated by 1-ethyl-3-methylimidazolium (EMIM)- and trihexyltetradecylphosphonium (THTDP)-based ILs was investigated using nuclear magnetic resonance (NMR), high-resolution mass spectrometry (HRMS) and differential scanning calorimetry (DSC) to increase our understanding of the curing mechanisms and their effect on the glass transition temperature (Tg) of the resultant epoxy networks. DSC experiments showed that 1-ethyl-3-methylimidazolium dicyanamide (EMIM-DCA) exhibited bimodal curing behavior, whereas phosphonium-based ILs and EMIM acetate (EMIM-Ac) showed single exothermic peaks consistent with a predominantly anion-mediated curing route. Chemical analysis of the thermally activated EMIM-DCA supported the analysis that the dual curing was the result of both anion- and cation-mediated routes by providing evidence for the formation of imidazole-derived species and for the possible involvement of carbene-related pathways. Additionally, molar ratio-matched EMIM-DCA and THTDP-DCA exhibited comparable curing temperatures for the primary exothermic peak, indicating that it was DCA-mediated. Interestingly, isothermal curing of EMIM-DCA showed that curing the sample at the intermediate temperature of 120 °C exhibited the highest Tg (134 °C), potentially due to contributions from both the anion and cation-mediated curing mechanisms, while curing at 80 °C and 170 °C resulted in lower Tg of 92 °C and 114 °C, respectively, due to curing mechanisms dominated by a single mechanism (cation and anion, respectively). These results highlight the influence of curing conditions on network properties.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":"6227-6237"},"PeriodicalIF":2.9,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943802","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 investigate size-dependent collective vibrational dynamics in self-assembled polystyrene nanoparticle films with particle diameters from 20 to 200 nm using VIPA-based Brillouin spectroscopy. A low-frequency band is assigned to an interaction-induced translational mode from its wavelength dependence, its separation from the intrinsic Lamb mode where both are accessible, and its persistence across the investigated size range. For particle diameters above approximately 100-150 nm, the mode frequency is consistent with Johnson-Kendall-Roberts (JKR) contact-mechanics scaling, f ∝ d-7/6. Below ∼100 nm, the response follows a weaker power-law dependence, f ∝ dγ with γ = -0.38 ± 0.12, indicating a deviation from homogeneous adhesive-contact scaling. Structural characterization over the same diameter range reveals reduced positional correlations and packing coherence, coincident with the change in vibrational scaling. Expressing the fitted branch as a contact-network velocity further shows that the sub-100 nm response reflects collective motion transmitted through a heterogeneous load-bearing network, rather than a bulk acoustic velocity. The measured scaling is consistent with an effective elastic-backbone description. These results establish a nanoscale crossover in the limits of applicability of classical contact mechanics and highlight mechanical connectivity as a key parameter governing collective vibrational dynamics in nanoparticle assemblies.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":"6285-6295"},"PeriodicalIF":2.9,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943768","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}

In a static, uniform magnetic field, dimers that are permanently fixed together hop between two preferred in-plane angles, developing a bimodal steady-state orientation distribution. When the same field is periodically reversed, we observe a sharp, field-controlled change in the dynamical response from small hopping events with Δθ ≪ π to full Δθ ≈ π rotations on each field flip. We show that both the static bistability and the switching bifurcation can be rationalised by a magnetic response in the dimer that consists of both a strong induced and weak body-fixed component. This leads to a complex orientational energy landscape, with coupled roll-yaw rotations of the dimer responsible for the bistable dynamics. By combining the misorientation between dimer axis and field, bifurcation field strength and short-time orientational variance, we determine the magnitude and orientation of the net permanent dipole, thereby characterising details of the internal magnetic structure of the particles via microscopy.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":"6198-6205"},"PeriodicalIF":2.9,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13626079/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148758548","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}

In this work, we contribute to this subject by presenting a comprehensive comparison of reentanglement dynamics between a highly stretched polymer probe in fixed networks and polymer melts containing equally stretched chains, from theoretical analysis and computer simulations. Whereas the relaxation of a polymer probe in networks can be well explained by the reptation theory, a new theoretical picture is proposed to describe the reentanglement process of a polymer melt, which predicts a relaxation pathway distinct from the network case. Nevertheless, the full recovery time in the melt remains consistent with the disentanglement time. These theoretical predictions are subsequently tested against two sets of simulations. Our single-chain Langevin simulations in networks show quantitative agreement with reptation theory for both equilibrium and reentanglement dynamics. In contrast, multi-chain melt simulations confirm qualitative differences from the network case when relaxing from a highly stretched state, consistent with our theoretical predictions. Other similarities and distinctions are examined through primitive path analysis and stress relaxation. Overall, our combined theoretical and simulation results enhance the understanding of experimental observations of reentanglement dynamics and provide new insights into out-of-equilibrium behavior across multiple time scales.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":"6206-6226"},"PeriodicalIF":2.9,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148757909","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}

In this work, we utilize the U-Net++ architecture to distinguish between textures corresponding to the crystalline B phase and the crystalline E phase. Both phases belong to the group of soft crystal phases and exhibit subtle morphological differences that make their identification challenging. For training purposes, texture datasets of both phases were combined into composite images, where regions of crystal B textures were embedded within crystal E backgrounds in the form of circular and rectangular patterns. This approach enabled the model to learn spatial features and phase boundaries more effectively. As a result of the analysis, we obtained pixel-wise probability maps and corresponding binary segmentation masks distinguishing the CrB and CrE phases. The proposed method demonstrates that deep learning may be useful for accurate and spatially resolved identification of liquid crystal phases. Moreover, this approach may provide a valuable tool for the quantitative determination of phase fractions, particularly within the very narrow temperature range of the CrB-CrE transition.
