Integration of Metal‐Organic Frameworks into Hydrogels: Optimizing Their Properties and Applications

Abstract In recent years, MOFs hydrogels have attracted extensive attention due to their unique structure and excellent performance. MOF‐based hydrogels combine the highly ordered pore structure and tunability of MOF with the biocompatibility and flexibility of hydrogels, and are widely used in environmental governance, sensors, and biomedicine. In this review, we mainly summarize the synthesis methods, structural characteristics and mechanical properties of MOF‐based hydrogels, and the specific applications of MOF‐based hydrogels in different fields including adsorption of heavy metal ions and pollutant gases stress strain sensor and drug delivery. Finally, we analyze the existing problems, and provide suggestions for the development direction of MOF‐based hydrogels in the future. This paper aims to help readers quickly understand the current development of MOF‐based hydrogels.
