Abstract
The invention discloses a preparation method of a graphene nanosilver composite material in the field of composite materials. The preparation method comprises the following steps: 1) mixing: oxide graphene and silver nitrate are mixed by a mass ratio of 1: 1.8-2.3, and are put in de-ionized water for ultrasonically dispersing by above 1 h; 2) reaction: the mixed liquid is put in a container to stir by above 18 h at room temperature; and hydrazine hydrate with a concentration of 80% and with a volume ratio of 2: 1 to the mixed liquid is added for standing by above 20 h at 95 DEG C; 3) cleaning: a reaction product is washed by the de-ionized water, and then, is washed by anhydrous ethanol; and 4) drying: the cleaned product is dried in vacuum at 30 DEG C to prepare graphene nanosilver. The prepared graphene/nanosilver composite material is excellent in electric conductivity, simple in production process and lower in cost, and saves the manpower and material resources.
