摘要

Abstract

The development of conductive hydrogels with stretchability

adhesiveness

self-healing

antibacterial and ionic conductivity is crucial for wearable electronic devices such as motion and health monitoring sensors and flexible generators. In this study

a novel multifunctional conductive hydrogel with high conductivity

excellent stretchability

antibacterial property

antifreeze and moisture retention

as well as self-healing and self-adhesive capabilities was successfully prepared by introducing the dynamic redox reaction between phenolic hydroxyl groups and Fe

through the addition of tannic acid (TA) to the acrylic acid (AA)-based hydrogel system

and the addition of LiTFSI. This material not only has good mechanical flexibility (tensile strength of 0.3048 MPa and elongation at break of 1657%)

but also stable electrical properties (conductivity of 1.47 S·m

–1

). The excellent antibacterial and self-healing properties also endow it with long-term stability in complex environments. The triboelectric nanogenerator (PTFL-TENG) constructed with this hydrogel can achieve an open-circuit voltage of approximately 100 V

th excellent and stable output performance

capable of providing self-powering ability for small electronic devices and enabling signal transmission. In addition

the self-powered sensor assembled with PTFL hydrogel can respond quickly and accurately to deformation and transmit electrical signals

demonstrating high sensitivity and good repeatability. Based on its comprehensive performance

this hydrogel has broad application prospects in flexible wearable sensors

intelligent medical monitoring

and self-powered systems.
