摘要
纳米共轭碳材料因其优秀的电化学性质与良好的导热性能,在储能、生物传感以及柔性器件等新材料领域引起广泛关注。然而,纳米共轭碳材料的疏水性导致它在水相中会发生团聚现象,难以分散转移,严重影响了纳米共轭碳材料的应用。如何在水相条件下合理、绿色地构建高性能纳米碳材料功能性涂层成为一个难点。简要综述了近几年来纳米共轭碳材料在水相中分散转移、固定化的研究进展,首先介绍了纳米共轭碳材料在水相条件下的分散转移方法:物理分散、共价修饰分散、非共价修饰分散;继而介绍了水相中分散的纳米碳材料不同的固定化的方法,包括水相自组装沉积法、电泳沉积法、真空抽滤法;简述了纳米共轭碳材料在光电器件和生物医药方面的应用;最后论述了水相分散纳米共轭碳材料所面临的挑战并展望了其未来发展方向。
Nano-conjugated carbon materials have attracted wide attention in the fields of energy storage,biosensors and flexible devices because of their excellent electrochemical properties and good thermal conductivity.However,nano-conjugated carbon materials will agglomerate in aqueous phase because of their hydrophobicity,which makes it difficult to disperse and transfer,which seriously affects the application of nano-conjugated carbon materials.It is difficult to construct high-performance functional coatings of nano-carbon materials reasonably and greenly under the condition of aqueous phase.In this paper,the research progress of dispersion transfer and immobilization of nano-conjugated carbon materials in aqueous phase in recent years is briefly reviewed.Firstly,the dispersion and transfer methods of nano-conjugated carbon materials in aqueous phase are introduced:physical dispersion,covalent modification dispersion and non-covalent modification dispersion.Different immobilization methods of nano-carbon materials dispersed in aqueous phase are introduced,including aqueous phase self-assembly deposition,electrophoretic deposition and vacuum filtration.The applications of nano-conjugated carbon materials in optoelectronic devices and biomedicine are briefly described.Finally,the challenges faced by aqueous dispersed nano-conjugated carbon materials are discussed and their future development directions are prospected.
