Method for preparing free-state polyhedron nano Ag particles

Provided is a method for preparing free-state polyhedron nano Ag particles. A Mo-Ag alloy film is deposited on a polyimide base, and a film base system of the Mo-Ag alloy film and the polyimide base is formed; the prepared film base system is subjected to argon atmosphere protection annealing treatm...

Zusammenfassung:	Provided is a method for preparing free-state polyhedron nano Ag particles. A Mo-Ag alloy film is deposited on a polyimide base, and a film base system of the Mo-Ag alloy film and the polyimide base is formed; the prepared film base system is subjected to argon atmosphere protection annealing treatment, and nanoscale pure silver particles are self-formed on the surface of the alloy film, that is,a nano Ag particle/silver alloy film composite structure is obtained; the prepared nano Ag particle/silver alloy film composite structure is soaked in a container containing absolute ethyl alcohol, the container is subjected to ultrasonic concussion under the ultrasonic condition, and the nano Ag particles are separated from the surface of the alloy film and enter absolute ethyl alcohol in the ultrasonic concussion process; and after ultrasonic concussion is carried out for 15 min, the film/base is taken out, then absolute ethyl alcohol in the container is evaporated, and the free-state polyhedron nano Ag particles ca
