Abstract:

Carbon dots hybrid hydrogel is a gel material with comprehensive properties of each component based on carbon dots and auxiliary materials. Inserting carbon dots into hydrogels can not only solve the fluorescence quenching effect caused by their aggregation, but also improve the performance of hydrogels and give them more abundant characteristics. At present, there is no detailed review of the structural characteristics of carbon dots, the performance enhancement mechanism, application fields and existing problems of carbon dots hybrid hydrogels. Therefore, this paper introduced the structural characteristics of carbon dots and common surface modification technologies, briefly described the preparation methods of carbon dots hybrid hydrogels, focused on the analysis of the performance enhancement mechanism of carbon dots on hydrogels, comprehensively summarized the applications of carbon dots hybrid hydrogels in wastewater treatment, bionic intelligent devices and other fields, and put forward the research trends of their applications in different fields. It was pointed out that in the face of broad space for composite hydrogel material design, the new material development strategy of computational simulation and theoretical prediction, followed by experimental verification, should be preferred to further enhance the application value of carbon dots hybrid hydrogel.

摘要：

碳点杂化水凝胶是以碳点和辅助物质为基础，形成具有各组分综合性能的凝胶材料。将碳点嵌入水凝胶中不仅可以解决其聚集引起的荧光猝灭效应，还可以提升水凝胶的性能并赋予其更丰富的特性。目前有关碳点的结构特性，碳点杂化水凝胶的性能增强机制、应用领域及存在的问题缺少详细的综述。因此，本文介绍了碳点的结构特性及常见的表面修饰技术，简述了碳点杂化水凝胶的制备方法，重点分析了碳点对水凝胶的性能增强机制，全面总结了碳点杂化水凝胶在废水处理、仿生智能器件等领域的应用并提出了其在不同领域应用时的研究趋势，指出面临广阔的复合水凝胶材料设计空间，应优先采用计算模拟和理论预测，再进行实验验证的新材料研发策略，进一步提升碳点杂化水凝胶的应用价值。
