▎ 摘　　要

NOVELTY - Producing graphene fibers containing metal nanoparticles involves forming graphene oxide dispersion by wet-spinning into a coagulation bath containing a metal ion selected from copper (Cu) ions, silver (Ag) ions, gold (Au) ions, and aluminum (Al) ions. The formed gel fibers are dried to produce graphene oxide fibers containing metal oxides. The dried gel fibers are treated with a chemical reducing agent to reduce metal oxides and graphene oxides. USE - Method for producing graphene fibers containing metal nanoparticles. ADVANTAGE - The method enables to produce graphene fibers containing metal nanoparticles that has high sensitivity to gas and temperature changes, good mechanical strength and high porosity, increases the flexibility and stretch of electronics, and improves conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a gas sensing or temperature sensing sensor, which comprises one or more graphene fibers containing metal nanoparticles.
