Carbon dots (CDs) are nanoscale carbon materials with unique optical properties and biocompatibility. Their applications are limited by their tendency to aggregate or oxidize in aqueous environments. Turning weakness to strengths, CDs can be incorporated with hydrogels, which are three-dimensional networks of crosslinked polymers that can retain large amounts of water. Hydrogels can provide a stable and tunable matrix for CDs, enhancing their fluorescence, stability, and functionality. CDs@hydrogels, known for their ease of synthesis, strong binding capabilities, and rich surface functional groups, have emerged as promising composite materials. In this review, recent advances in the synthesis and characterization of CDs@hydrogels, composite materials composed of CDs and various types of natural or synthetic hydrogels, are summarized. The potential applications of CDs@hydrogels in fluorescence sensing, adsorption, drug delivery, antibacterial activity, flexible electronics, and energy storage are also highlighted. The current challenges and future prospects of CDs@hydrogels systems for the novel functional materials are discussed.
碳点（CDs）是具有独特光学性质和生物相容性的纳米级碳材料。它们的应用受到其在水性环境中聚集或氧化倾向的限制。化劣势为优势，碳点可与水凝胶结合，水凝胶是交联聚合物的三维网络，能够保留大量水分。水凝胶可为碳点提供稳定且可调的基质，增强其荧光、稳定性和功能性。碳点@水凝胶以其易于合成、强大的结合能力和丰富的表面官能团而闻名，已成为有前景的复合材料。在这篇综述中，总结了碳点@水凝胶（由碳点与各种天然或合成水凝胶组成的复合材料）在合成和表征方面的最新进展。还强调了碳点@水凝胶在荧光传感、吸附、药物递送、抗菌活性、柔性电子和能量存储方面的潜在应用。讨论了碳点@水凝胶体系作为新型功能材料目前面临的挑战和未来前景。
