摘要
Hydrogels have blossomed as superstars in various fields,owing to their prospective applications in tissue engineering,soft electronics and sensors,flexible energy storage,and biomedicines.Two-dimensional(2D)nanomaterials,especially 2D mono-elemental nanosheets(Xenes)exhibit high aspect ratio morphology,good biocompatibility,metallic conductivity,and tunable electrochemical properties.These fascinating characteristics endow numerous tunable application-specific properties for the construction of Xene-based hydrogels.Hierarchical multifunctional hydrogels can be prepared according to the application requirements and can be effectively tuned by different stimulation to complete specific tasks in a spatiotemporal sequence.In this review,the synthesis mechanism,properties,and emerging applications of Xene hydrogels are summarized,followed by a discussion on expanding the performance and application range of both hydrogels and Xenes.
