Abstract:  Nano-conjugated carbon materials have attracted wide attention in the fields of energy storagebiosensors and flexible devices because of their excellent electrochemical properties and good thermal con-ductivity. However, nan-conjugated carbon materials will agglomerate in aqueous phase because of theirhydrophobicity, which makes it difficult to disperse and transfer, which seriously affects the application ofnano-conjugated carbon materials. It is difficult to construct high-performance functional coatings of nanocarbon materials reasonably and greenly under the condition of aqueous phase. In this paper, the re-search progress of dispersion transfer and immobilization of nano-conjugated carbon materials in aqueousphase in recent years is briefly reviewed. Firstly, the dispersion and transfer methods of nano-conjugatedcarbon materials in aqueous phase are introduced: physical dispersion, covalent modification dispersionand non-covalent modification dispersion. Different immobilization methods of nano-carbon materials dis.persed in aqueous phase are introduced, including aqueous phase self-assembly deposition , electrophoretic deposition and vacuum filtration. The applications of nano-conjugated carbon materials in optoelectron-ic devices and biomedicine are briefly described. Finally, the challenges faced by aqueous dispersednano-conjugated carbon materials are discussed and their future development directions are prospected.
