Abstract:

Ionic conductive hydrogels are polymeric materials with high water content, stretchability and good biocompatibility. The presence of free ions in polymer networks enable them to exhibit ionic conductivity very similar to human skin, showing great potential in applications such as wearable sensing devices, energy storage devices, and biomedical applications. In this review, the research background and progress of ionic conductive hydrogels were briefly introduced, and the preparation methods of ionic conductive hydrogels were discussed. The research progress of ionic conductive hydrogels in functional properties such as conductivity, flexibility, anti-freezing, water retention, self-healing, adhesion and biocompatibility was introduced, and the related application research progress of ionic conductive hydrogels was analyzed and described. Finally, the existing problems and challenges in stability, environmental suitability and synergetic compatibility between various functions of ionic conductive hydrogels were summarized, and the development trend and prospect of ionic conductive hydrogels were forecasted. It was pointed out that the development of functionally adjustable ionic conductive hydrogels with high conductivity, superior stability in an extreme environment, perfect self-healing properties and desirable biodegradability would be the focus of further research. In addition, it would also become an important research direction to develop a wearable sensing system with wireless sensing and self-powered function based on ionic conductive hydrogels.

Key words: hydrogels, ionic conductive, self-healing, flexible electronic
