Cu-Ag bimetallic nano material, preparation method and application thereof

The invention provides a Cu-Ag bimetallic nano material, a preparation method and application thereof, and belongs to the field of nano materials. The preparation method comprises the steps of preparing a polyatomic alcohol solution of silver nitrate, a polyatomic alcohol solution of polyvinylpyrrolidone and a polyatomic alcohol solution of copper acetate; mixing the polyatomic alcohol solution of silver nitrate with the polyatomic alcohol solution of polyvinylpyrrolidone according to the fact that the volume ratio of the polyatomic alcohol solution of silver nitrate to the polyatomic alcohol solution of polyvinylpyrrolidone is 1 to (1 to 1.2), and carrying out microwave treatment to obtain an Ag nano solution; mixing an n-heptanol solution of copper acetate with the Ag nano solution according to the volume ratio of the n-heptanol solution of copper acetate to the Ag nano solution is 1 to (1 to 1.2), and carrying out microwave treatment to obtain Cu-Ag nano sol suspension; and carrying out centrifugal cleaning on the Cu-Ag nano sol suspension, and removing supernate to obtain the Cu-Ag bimetallic nano material. The preparation method of the Cu-Ag bimetallic nano material provided by the invention is simple and reliable to use and environment-friendly in technology. The invention further discloses the Cu-Ag bimetallic nano material prepared through the method and application of the Cu-Ag bimetallic nano material as an antibacterial agent.
