However, its inherently low triboelectric polarity severely limits its application in flexible wearable sensor systems. Herein, a hemicellulose-based composite film with excellent triboelectric properties was designed. Acrylamide (AM) monomers were grafted onto the hemicellulose backbone through a free radical graft copolymerization reaction. The amino group's strong electron-donating capability enhanced molecular polarization. Synergistic dynamic hydrogen/covalent bonding networks improved mechanical properties (strength, fatigue/thermal expansion resistance) through optimized cohesive energy, thereby boosting charge transfer and significantly enhancing macroscopic triboelectric performance. The HC/PAM4-based TENG delivers 81 V open-circuit voltage, 6.6 µA short-circuit current, 10 nC transferred charge, and 49 mW/m2 peak power density at 1 Hz. Self-powered, the device monitored human motion by analyzing distinct signal waveforms for precise recognition. The HC/PAM4 film retains recyclability through water dissolution-drying cycles via dynamic hydrogen bonds, maintaining stable properties over 5 cycles: water solubility time (140 ± 2 s), tensile strength (10 ± 2 MPa), and elongation at break variation (<5%) under ambient conditions, demonstrating excellent long-term stability. Our finding offers an effective strategy for enhancing hemicellulose-based triboelectric materials, enabling wearable self-powered sensors toward eco-friendly intelligent devices.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00340"},"PeriodicalIF":4.3,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144870562","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}

The incorporation of ground tire rubber (GTR) into NR enhances strain-induced crystallization (SIC), reducing the onset strain for crystallization and increasing mechanical reinforcement. Cyclic loadings reveal significant hysteresis and residual deformation, influenced by GTR content. Moreover, the strain at complete melting of SIC crystals is found to decrease with GTR content, suggesting a higher stability of SIC crystals. Under combined tensile stress and high temperature, NR/GTR blends exhibit failure likely due to decohesion at the NR/GTR interface and growth of cavities in the NR matrix. Nonetheless, the temperature at fracture is increased by 15°C with the GTR content at a strain of 300%. As SIC crystals promote resistance to crack growth, failure is delayed under high stress and temperature owing to the nucleating effect of GTR on SIC. In spite of the limitations imposed by the interface between NR and GTR, the study highlights the role of GTR in the promotion of SIC in reinforcing NR-based composites.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00480"},"PeriodicalIF":4.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843889","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}

This study presents a novel PLA/APHA/TPU blend filament for 3D printing that overcomes this limitation by combining high strength and flexibility with low-temperature shape memory activation-features not previously achieved in PLA-based SMPs. The uniform dispersion of TPU and APHA in the PLA matrix creates a composite with enhanced tensile strength, modulus, and elongation, addressing the brittleness typical of neat PLA. The optimized 60/20/20 wt.% formulation enables rapid shape recovery at ∼39.5°C, significantly below PLA's glass transition, with near-complete shape fixity (∼100%) and high recovery ratios (>92%) under both thermal and mechanical stimuli. This dual-responsive behavior is driven by the synergistic roles of TPU (providing ductility) and APHA (enhancing flexibility and thermal sensitivity). The composite also retains excellent printability and biocompatibility, making it ideal for next-generation biomedical SMP applications such as 4D-printed orthopedic braces, soft robotic actuators, and adaptive implants. Using bio-based, biodegradable polymers, this work advances eco-friendly, high-performance SMPs for additive manufacturing, setting a new benchmark for PLA-based 4D-printable materials.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00414"},"PeriodicalIF":4.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843891","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}

Recent research has focused on incorporating viscous and elastic properties into hydrogels to investigate cellular responses to time-dependent mechanical properties of the ECM. However, a critical aspect is that cells continuously remodel their microenvironment in hydrogels, such as by the deposition of newly secreted (nascent) ECM. While this nascent ECM has been demonstrated to play a vital role in transmitting mechanical signals across various biological contexts, the mechanisms by which it regulates cellular function in response to time-dependent mechanical properties remain poorly understood. In this study, we developed an interpenetrating polymer network that enables independent control of viscous and elastic hydrogel properties. We show that cells cultured on high-viscosity hydrogels deposit increased nascent ECM, which also correlates with enhanced hydrogel remodeling. Interestingly, higher nascent ECM deposition on high-viscosity hydrogels was decoupled from intracellular contractility. These results establish a relationship between hydrogel viscosity and nascent ECM deposition that may extend to diverse cell types and offer new insights into cell-hydrogel interactions.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00435"},"PeriodicalIF":4.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843892","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}

To achieve this, a hydrophilic poly(N,N-dimethylacrylamide) (PMDAc) was functionalized at one chain-end with a perylene diimide (PDI) sticker using RAFT polymerization. Two PDI RAFT agents were prepared and studied: one featuring two tri(ethylene glycol) (TEG) units at the PDI bay-positions and one without. The corresponding PDI-PDMAc conjugates spontaneously self-assembled in water, driven by π-π interactions made of H-aggregates, and showed a morphological evolution from cylinders to spheres when increasing the polymer chain length. The introduction of TEG units was found to be important to avoid the clustering of nanocylinders or the formation of ill-defined assemblies, which were observed in the TEG-free system. Moreover, we found that the PDI-TEG2-PDMAc with degrees of polymerization (DPn) below 24 self-assembled into micrometer-long nanocylinders. By heating the aqueous polymer solution, this process can be accelerated and is accompanied by a large increase in viscosity. Fluorescence spectroscopy revealed an excimer emission signal for the PDI polymers in water, with a higher emission for cylinders, suggesting better organization within the PDI H-aggregates. This strategy provides a sustainable approach for developing functional nanomaterials with precise morphological control, eliminating organic solvents and complex processing.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00478"},"PeriodicalIF":4.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843890","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 synthesis of micelles with precise structures often involves complex process. Herein, we developed a novel multi-responsive micelles hydrogel GBN, which was prepared by combining the polymerization-induced self-assembly (PISA) of poly(N-isopropyl acrylamide)-poly (glycerol methacrylate) (PGMAx-PNIPAM) and B─O crosslinking the micelles. The yielded micelles with stable worm-like structures, easily form a hydrogel through significant entanglement. The thermo-responsiveness of these micelles facilitates a reversible gel-sol transition, accompanied by changes in transparency, making them suitable for thermal management in smart window applications. Additionally, the glucose responsiveness associated with the dynamic B─O bonds address the incompatibility of PNIPAM's LCST temperature for drug release applications. Importantly, we discovered that the GNB hydrogel can also function as sealing material; its thermo-responsiveness enables the formation of liquid gaskets that uniformly fill rough surfaces. In its gel state, it exhibits stable load-bearing capacity, sealing strength, and consistent friction coefficients, making it applicable in both static and dynamic sealing scenarios to tackle sealing challenges in extreme environments.

Precise engineering of physical properties, especially size, of nanoparticles using electrohydrodynamic (EHD) jetting is a crucial factor that defines the fate of delivery systems in nanomedicine. Herein, we establish a systematic understanding that leads to the preparation of human serum albumin (HSA) nanoparticles with sizes as small as 50 nm. Interestingly, the addition of salt at very low concentrations, around 1-5 mm, combined with EHD process parameters, can result in narrow distributions of particle sizes that are consistently below 100 nm. At a given concentration, i.e., 2 mm, anions modulate the particle diameters that follow the Hofmeister Series as SO4 2- < CO3 2- < H2PO4 - < Cl- < I-. This size reduction is primarily due to increased solution conductivity and interfacial charge density induced by salt ions during the EHD jetting process. High mobility ions compensate for the higher surface energy required to produce ultra-small nanoparticles. Tight control over the size and distribution of ultra-small nanoparticles may be critical for targeted drug delivery, as it can influence nanoparticle tropism or affect their cellular uptake.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00533"},"PeriodicalIF":4.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843894","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}

Importantly, the PU elastomer possessed not only high healing efficiency of 96.6% after healing at 60°C for 24 h, but also superior reprocessability with a tensile strength retention rate of 75.6% after three reprocessing cycles. Besides, owing to residual phenolic hydroxyl groups in unreacted PA, the PU elastomer also exhibited outstanding thermal-oxidative aging resistance.
