The invention discloses a preparation method of a nano silver-loaded fluorinated
graphene composite. The preparation method comprises the steps of 1) placing a
graphene film in a PECVD
reaction chamber, setting the pressure at 5*10<-4> to 10<-3> Pa, setting the temperature at 200 to 600 DEG C, setting
plasma generation
microwave power at 300 to 500 W, introducing
fluorine gas through adopting
argon as a carrier, and reacting for 1 to 20 h to obtain a fluorinated
graphene film; 2) transferring the obtain fluorinated graphene film into an atom
deposition chamber, degassing for 20 min to 30 min through adopting an
inert gas, regulating the vacuum degree of an ultravacuum
reaction chamber to 10<-6> to 10<-7> Pa, and regulating the temperature to 400 DEG C to 700 DEG C; and 3) adopting silver as a target material, forming a silver reaction gas source through
electron beam bombardment
evaporation, introducing the silver reaction gas source into the
deposition chamber for 20 to 100 ns, introducing an
inert carrier gas for 50 to 200 ns, repeating the steps for 5 to 20 min, alternatively introducing the silver reaction gas source and the
inert carrier gas, and forming nano silver on the fluorinated graphene film, so as to obtain the nano silver-loaded fluorinated graphene composite. The obtained composite has excellent performance.
