High‐Strength, Antiswelling Directional Layered PVA/MXene Hydrogel for Wearable Devices and Underwater Sensing

Advanced Science, Год журнала: 2024, Номер 11(39)

Опубликована: Авг. 20, 2024

Abstract Hydrogel sensors are widely utilized in soft robotics and tissue engineering due to their excellent mechanical properties biocompatibility. However, high‐water environments, traditional hydrogels can experience significant swelling, leading decreased electrical performance, potentially losing shape, sensing capabilities. This study addresses these challenges by leveraging the Hofmeister effect, coupled with directional freezing salting‐out techniques, develop a layered, high‐strength, tough, antiswelling PVA/MXene hydrogel. In particular, process enhances self‐entanglement of PVA, resulting an S‐PM hydrogel tensile strength up 2.87 MPa. Furthermore, retains its structure after 7 d only 6% change resistance. Importantly, performance is improved postswelling, capability rarely achievable hydrogels. Moreover, demonstrates faster response times more stable resistance rates underwater tests, making it crucial for long‐term continuous monitoring challenging aquatic ensuring sustained operation monitoring.
