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.
水凝胶已成为各个领域的明星材料，这得益于它们在组织工程、柔性电子与传感器、柔性储能以及生物医学等方面的潜在应用。二维（2D）纳米材料，尤其是二维单元素纳米片（烯类）呈现出高纵横比形态、良好的生物相容性、金属导电性以及可调控的电化学性质。这些迷人的特性赋予了基于烯类的水凝胶众多可调控的特定应用性能。可以根据应用需求制备分级多功能水凝胶，并通过不同刺激进行有效调控，从而按时空顺序完成特定任务。在本综述中，总结了烯类水凝胶的合成机理、性质及新兴应用，随后讨论了如何拓展水凝胶和烯类的性能及应用范围。
