Abstract Hydrogels have emerged as fascinating material for various applications in the chemical, biomedical, and energy fields. Generally, their poor self-healing performance, mechanical properties, and bioactivity limit the application of hydrogels in bioelectronics. Herein, a self-healable, injectable, stretchable, self-adhesive, biocompatible, and conductive poly(N-vinylpyrrolidone)/gallic acid (PVP/GA) composite hydrogel was fabricated via hydrogen bonding between the tertiary amide groups in PVP and hydroxyl groups in GA. The PVP/GA composite hydrogel possesses excellent self-healing properties after damage. The composite hydrogel is highly stretchable and can adhere to human skin to detect physiological activity signals precisely according to the resistance signals. The composite hydrogel has good biocompatibility with living organisms. It is envisioned that multifunctional PVP/GA composite hydrogels can be applied to the electronic skins, wearable biosensors, and body movements monitoring equipment.

通过氢键形成的自修复、可拉伸和导电的聚(N-乙烯基吡咯烷酮)/没食子酸复合水凝胶用于可穿戴电子传感器

摘要 水凝胶已成为化学、生物医学和能源领域各种应用的迷人材料。通常,它们较差的自愈性能、机械性能和生物活性限制了水凝胶在生物电子学中的应用。在此,通过 PVP 中的叔酰胺基团与羟基之间的氢键,制备了一种自修复、可注射、可拉伸、自粘、生物相容性和导电的聚(N-乙烯基吡咯烷酮)/没食子酸(PVP/GA)复合水凝胶在 GA 中。PVP/GA 复合水凝胶在损伤后具有优异的自修复性能。复合水凝胶具有高度的可拉伸性,可以粘附在人体皮肤上,根据电阻信号精确检测生理活动信号。该复合水凝胶与生物体具有良好的生物相容性。
