NOVELTY - Preparation of a self-assembled ferroferric oxide silver particles/graphene oxide nanochain involves adding silver sol, graphene oxide and ferroferric oxide in a mass ratio of 10:1:1-10:1:2 and mixing uniformly, adding and mixing sodium chloride solution under ultrasonic conditions, removing the supernatant by centrifuging, and dispersing the precipitate in water. USE - Preparation of self-assembled ferroferric oxide silver particles/graphene oxide nanochain. ADVANTAGE - The method is simple to operate, fast and does not require a binder, and has improved reliability of the silver nanochain synthesize, and repeatability. The graphene oxide controls the size of the agglomerates, stabilizes nanoparticles and its agglomerates, provides huge space for surface cleaning of the nanoparticles, and regulates the surface plasmon resonance.
