The present invention comprises a) wet spinning a graphene oxide dispersion in a coagulation bath containing a metal ion selected from the group consisting of copper (Cu) ions, silver (Ag) ions, gold (Au) ions, aluminum (Al) ions Forming gel fibers; b) drying the formed gel fibers to produce graphene oxide fibers containing metal oxides; And c) treating the dried gel fibers with a chemical reducing agent to reduce metal oxides and graphene oxides, thereby providing a method for producing graphene fibers containing metal nanoparticles. May be usefully used for gas sensing and / or temperature sensing sensors. |
