Multifunctional Nano‐Conductive Hydrogels With High Mechanical Strength, Toughness and Fatigue Resistance as Self‐Powered Wearable Sensors and Deep Learning‐Assisted Recognition System

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 20, 2024

Abstract High mechanical strength, toughness, and fatigue resistance are essential to improve the reliability of conductive hydrogels for self‐powered sensing. However, achieving mutually exclusive properties simultaneously remains challenging. Hence, a novel directed interlocking strategy based on topological network structure training is proposed construct tough by optimizing modulating orientation molecular chains. Combining Zn 2+ crosslinked cellulose nanofibers (CNFs) polyacrylamide‐poly(vinyl alcohol) double‐network, unique interlocked‐network exhibits an enhanced toughening effect due hydrogen bonding metal‐ligand interactions. The aligned nanocrystalline domains achieved further contribute increase in toughness thresholds. This innovative approach synergistically enhances nano‐conductive hydrogel, maximum tensile strength 4.98 MPa 48 MJ m −3 . Notably, CNFs template with anchored polyaniline, when oriented through training, forms directional pathway, which significantly power output performance. Besides, motion recognition system sensing device designed assistance deep learning techniques accurately identify human behaviors. work showcases potentially transformative flexible electronic material systems intelligent systems.
