Abstract:

Conductive hydrogels, a type of novel hydrogels which organically combine hydrophilic matrix and conductive medium, have plentiful insights and opportunities in flexible electronic devices and other fields because of their excellent flexibility, adjustable mechanical properties and outstanding electrochemical performances. In this review, the research frontiers and trends of conductive hydrogel materials were provided. The methods of classification and preparation of conductive hydrogels were introduced, and their design and performance of conductive hydrogels were discussed. Furthermore, the application research progress of conductive hydrogel materials was expounded thoroughly, and their problems and challenges were concluded. Finally, the development trend of conductive hydrogel materials was prospected, and it was pointed out that the use of natural raw materials in the exploration of conductive hydrogels with high conductivity, stable mechanical properties, extreme temperature tolerance, biocompatibility and biodegradability would be the focus of further research, while optimizing flexible electronic devices and improving the output stability of devices would also become an important research direction. The research on the fabrications and applications of conductive hydrogels can promote the rapid development of flexible electronic functional materials.
