Yet, the deployment of DNA-based functional materials remains limited due to insufficient control over the emerging structures and their mechanics. In an ongoing effort to place structure-property relations in stimuli-responsive DNA materials on a firm foundation, here a systematic rheological study of self-assembling DNA networks is presented, comprised of short DNA nanomotifs, namely trivalent nanostars and bivalent linkers, where the latter differ in their composition on a single base-pair level. Notably, we found through combining conventional bulk rheology with diffusing wave spectroscopy (DWS-based) passive microrheology a relationship between the melting temperature of a DNA hydrogel and its DNA sequence composition. By providing a use case, we demonstrated how the determination of such empirical relations could impact the areas of biosensing and mechanical computing, where control over the system state and target identification are key.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500149"},"PeriodicalIF":4.2,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955239","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, the TEMPO-oxidized cellulose nanofibers-Graphene nanosheets/poly(vinyl alcohol)-sodium alginate-tannic acid (TOCN-GN/PVA-SA-TA, TGG) composite hydrogel fibers are prepared by microfluidic spinning technology to solve the bottleneck problems of poor dispersion of GN and imbalance of mechanical-conductive properties of traditional hydrogels. TOCN, acting as a biotemplate, effectively inhibits GN agglomeration via hydrogen bonding and mechanical interlocking, thereby enhancing GN dispersion and facilitating the formation of 3D conductive networks within hydrogel fibers. The optimized TGG fibers achieved a tensile strength of 0.96 MPa, 150% elongation at break, and electrical conductivity of 2.66 S m-1, while exhibiting enhanced energy dissipation and fatigue resistance. As strain sensors, TGG fibers demonstrated high sensitivity (gauge factor is 1.81 at 40-100% strain) and rapid response (≈0.3 s), enabling precise monitoring of joint movements, facial micro-expressions, and swallowing actions. Furthermore, PDMS-encapsulated textile sensors enabled encrypted Morse code transmission, demonstrating innovative potential for next-generation flexible electronics in health monitoring and human-machine interfaces.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500222"},"PeriodicalIF":4.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952137","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}

Nuclear Magnetic Resonance (NMR) and Infrared spectroscopies revealed the full conversion of the PDMS terminal epoxides to aldehyde groups. This new aldehyde functional PDMS is then used to elaborate aliphatic self-healing materials through imine chemistry by reaction with an amine-terminated PDMS featuring urea moieties in its structure. The reactivity of the aldehyde terminated PDMS is investigated through the preparation of supramolecular networks formed by the hydrogen bonds of ureas. The incorporation of permanent chemical cross-linking points through reaction with a triisocyanate leads to the preparation of covalent adaptable networks (CANs). As a result, materials with a wide range of mechanical properties are obtained, depending on the composition and structure of the PDMS networks. Due to the presence of dynamic covalent imine bonds, the supramolecular networks show excellent scratch recovery at room temperature while the CANs retain their mechanical properties after two cycles of reshaping by heating.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500173"},"PeriodicalIF":4.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144052893","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 lack of circularity poses critical environmental threats. However, upcycling-recycling materials while improving their properties and functionality-through dynamic bonding strategies offers a promising approach to enhancing polymer sustainability. Dynamic bonds enable polymeric structures to reconfigure under specific conditions, improving thermal, chemical, and mechanical resilience and controllability while facilitating recyclability. This review specifically takes the viewpoint of upcycling existing thermoplastics and thermosets to develop sustainable dynamic covalent networks (DCNs). Integrating these DCN upcycling strategies into the design of additive manufacturing (AM) feedstocks creates unique benefits compared to traditional polymer systems. This approach is briefly highlighted in extrusion-based and light-based AM, assessing the potential for improved material processability, recyclability, and the creation of high-value customized products. The combination of upcycling technologies and AM techniques presents a significant opportunity to advance sustainability in macromolecular science.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2401011"},"PeriodicalIF":4.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955524","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, its inherent stiffness limits flexibility. To address this, lignin is copolymerized with bis(3-aminopropyl)-terminated poly(dimethylsiloxane) (PDMS-NH2), introducing tunable elasticity and improved mechanical properties. Lignin is first modified with CO₂ to produce cyclic carbonate-functionalized lignin (CCL). The CCL reacts with PDMS-NH2 amines via the ring-opening of cyclic carbonates, forming soft-hard polyhydroxyurethane copolymers with adjustable properties (CCL-PDMS-PHUs). Structural characterization confirms urethane bond formation, with peaks at 1680 cm⁻¹ (FT-IR) and chemical shifts at 161.33 ppm (¹3C NMR) and 7.99 ppm (¹H NMR). Thermal analysis reveals 5% decomposition temperatures of 246-265 °C and glass transition temperatures (Tg) ranging from 44 to 66 °C, indicating tunable thermal stability. Mechanical testing shows that CCL-PDMS-PHU60 (60% PDMS-NH2) exhibited greater softness, while CCL-PDMS-PHU40 (40% PDMS-NH2) displayed higher stiffness, highlighting PDMS-NH2's effect on flexibility. These results demonstrate that CCL-PDMS-PHUs offer customizable mechanical and thermal properties, making them promising materials for applications requiring tailored elasticity and thermal performance.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500070"},"PeriodicalIF":4.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143961787","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}
