Here, six core properties were studied, including Young's modulus (YM), tensile strength (TS), elongation at break (EB), glass transition temperature (Tg), decomposition temperature at 5% weight loss (Td5), and the energy dissipation factor (tanδ). We compiled a new dataset comprising more than 1500 samples with comprehensive information in composition, process, structure, and properties. Through domain-knowledge augmented feature engineering, a set of 26 features is sufficient to predict these core properties. Multi-target regression models for YM, TS, and EB delivered coefficients of determination (R2) better than 0.70 from validation and blind tests, and higher than 0.80 in the prediction of the remaining three properties, Tg, Td5, and tanδ. Features to describe the chemical structure of polyurethane monomers and their formulation are dominant, and they contributed more than 70% of the explainability. Biomass feedstocks, molecular weights for polyols, hard segment contents etc., are important regulatable variables to prepare BPUEs with fitting-for-purpose products, and the stretching rate and the heating rate are also critical to harvest repeatable mechanical and thermal properties. This study provided data-driven insights for the rational design of BPUEs with desired mechanical and thermal properties.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00963"},"PeriodicalIF":4.3,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147363530","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, their strong polarity often leads to migration from the bulk to the surface, adversely affecting product appearance and reducing long-term anti-aging performance, which limits their wider use. To address this, a novel antioxidant, EMA2-PPDA (designated E2P), was synthesized by attaching two 3,4-epoxycyclohexylmethyl acrylate (EMA) units to an N-phenyl-p-phenylenediamine (PPDA) core via an epoxy-amine reaction. E2P exhibits a notable capacity to react during vulcanization. This characteristic can improve its retention within diene rubber matrices, making it less prone to migration compared to the conventional antioxidant 6PPD (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine). Results show that E2P provides excellent anti-aging protection in both natural rubber (NR) and butadiene rubber (BR), with the best overall thermal-oxidative stability observed at 3 phr (parts per hundred rubber). In addition, E2P exhibits a markedly improved resistance to migration compared to 6PPD under the investigated conditions. These findings indicate that introducing acrylate groups represents a promising strategy for improving the migration resistance of PPD-type antioxidants in vulcanizates, without compromising their antioxidative activity.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00002"},"PeriodicalIF":4.3,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147346958","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}

Polymerization-induced self-assembly (PISA) provides an efficient and versatile route for preparing such structures. However, the critical role of hydrophilic stabilizers with tailored architectures in PC fabrication has remained incompletely understood. Herein, we investigate the effect of stabilizers containing poly (ethylene glycol) (PEG) oligomeric side-chains with elaborate adjustment of position and content on the formation of PCs via PISA. The stabilizers include poly(poly (ethylene glycol) methyl ether methacrylate (oE), poly(hydroxypropyl methacrylate (H), and their block copolymers (oE-b-H and H-b-oE), and the core-forming monomer is styrene (St). Compared with the homopolymer-type stabilizers, a high feeding ratio of St to stabilizers is needed to form PCs for block copolymer-type stabilizers. This is attributed to impeded morphological fusion resulting from incompatibility between oE and H segments. Additionally, increasing the oE content in H-b-oE-type stabilizers leads to a more substantial St amount for preparing PCs than in oE-b-H-type stabilizers. We propose that excess St acts as a plasticizer, mitigating the strong steric hindrance imposed by PEG side-chains near the hydrophobic/hydrophilic interface. We believe that this work will enrich the fundamental research for PISA-mediated PC preparation through stabilizer engineering.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e70250"},"PeriodicalIF":4.3,"publicationDate":"2026-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147321000","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}

Herein, we present a synergy of orthogonal photochemistry and Hofmeister effect strategy for the rapid fabrication of high-performance conductive hydrogels. Under visible light, ruthenium photochemistry triggers three orthogonal reactions comprising the radical polymerization of poly(vinyl alcohol acetoacetate), the oxidative polymerization of ethylenedioxythiophene, and the phenol coupling of gelatins within seconds. A subsequent Hofmeister effect-mediated post-treatment induces hierarchical polymer crystallization to endow the hydrogels with exceptional toughness of 3.1 MJ m-3 and fatigue resistance. Furthermore, the dynamic hydrogen-bonding network and gelatin grant the hydrogel a rapid self-healing efficiency of approximately 90%. The resulting hydrogels are fully compatible with extrusion-based 3D printing to enable the fabrication of customizable and self-healing resistive and capacitive sensors capable of reliable motion monitoring. This work establishes a versatile and efficient platform for engineering multifunctional soft materials for wearable devices.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00005"},"PeriodicalIF":4.3,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147300420","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, accurate sensitivity for tiny deformation and low electrical conductivity are still limitations for ideal hydrogel sensors and electrodes. In this work, a multifunctional conductive polyelectrolyte hydrogel was prepared with cationic monomer 3- (methacryloylamino) propyl-trimethylammonium chloride, at the same time, polyphenolic compound tannic acid and glycerol were introduced to the hydrogel network to enhance the adhesion performance and environmental tolerance. The polyelectrolyte hydrogel showed low hysteresis (below 10%), good self-adhesion (∼50 kPa), excellent biocompatibility and antibacterial activity, satisfactory conductivity (8.5 mS m-1), long-term stability (∼10 000 repeated cycles), wide strain sensing range (0.1%-100%), and accurate sensitivity even for human pulse monitoring. A flexible wearable device was designed for real-time monitoring of multiple movements and outdoor sports. In addition, a reusable self-adhesive electrode was designed based on the polyelectrolyte hydrogel for physiological signal monitoring, including electroencephalogram (EEG), electrocardiogram (ECG), and electromyogram (EMG). The electrode exhibited a superior signal-to-noise ratio, long-term stability, and sensitivity compared to traditional commercial electrodes. This study provides a promising material platform for long-term stable and accurate signal monitoring in flexible wearable electronics.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00877"},"PeriodicalIF":4.3,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163257","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}
