<p>Hydrogels featuring randomly networked matrix typically show poor mechanical strength owing to the weak interchain interactions of matrix. Encouragingly, stretchability and toughness hydrogel materials along a certain direction were recently improved an unprecedented level with design structured oriented matrix, realization excellent concurrently isotropic performance for hydrogels now become next- research goal. Herein, self-assembling process poly(vinyl alcohol) (PVA) macromolecular chain cellulose nanofibril (CNF) induced by salting-out effect was reported, which allowed formation strongly hydrogen-bonded PVA-CNF supramolecular The resulting hydrogel, in any direction, can ultra-high 7,400% true tensile 420 MPa through orientation robustness interaction between PVA CNF experimentally demonstrated fact that showed high fracture energy (reaching up 95.7 kJ m⁻²) low notch sensitivity (fatigue threshold 3,203 J m⁻²), even outperforming most state-of-the-art anisotropic hydrogels. These results highlight constructing among various components gel holds great promise future extraordinary performance.</p>

A Universal Strategy to Mitigate Microphase Separation via Cellulose Nanocrystal Hydration in Fabricating Strong, Tough, and Fatigue‐Resistant Hydrogels

Advanced Materials, Год журнала: 2024, Номер 37(7)

Опубликована: Дек. 29, 2024

Abstract As a common natural phenomenon, phase separation is exploited for the development of high‐performance hydrogels. Using supersaturated salt to create microphase‐separated hydrogels with strengthened mechanical properties has gained widespread attention. However, such hydrogel loses its intrinsic flexibility, making strategy unsuitable fabrication stretchable and tough Here, phase‐engineering design introduced produce yet using NaAc salt, by leveraging hydration effect cellulose nanocrystal (CNC) mitigate microphase separation. The CNC‐mitigated presents unprecedented properties, example, tensile strength 1.8 MPa fracture strain 4730%, toughness 43.1 MJ m −3 , energy 75.4 kJ −2 fatigue threshold up 3884.7 J . Furthermore, this approach universal in synthesizing various separation‐enhanced polymer gels, including polyacrylic acid, poly(acrylic acid‐co‐acrylamide), gelatin, alginate. These advancements provide insights into incorporation CNC‐mediated structures hydrogels, which will foster future soft materials.
