Abstract:Hydrogels were widely employed in biomedical, functional materials and chemical biosensor, due to their excellent physical, chemical and biological properties. Conductive hydrogels were favored by many researchers.So far, various types of conductive polymers (ECHs) have been developed by combining various conductive components and different types of polymer matrixes with conductive fillers.In this review, recent progress in the field of conductive hydrogels was summarized, and the method of design and construction of conductive hydrogels was expounded thoroughly. Finally, their applications in the field of biomedicine and energy storage systems were discussed. The research on the design and applications of conductive hydrogels can promote the rapid development of functional materials.
