Polymer-based silver- carrying graphene nano antibacterial material preparation method

The present invention discloses a polymer-based silver- carrying graphene nano antibacterial material preparation method, a polymer-based silver- carrying graphene nano antibacterial material comprises 75 to 90 by weight parts of matrix resin, 10 to 20 by weight parts of a polystyrene / silver- carrying graphene composite, and 0.05 to 0.2 by weight part of an antioxidant; the preparation method is as follows: melting and blending the matrix resin, the polystyrene / silver- carrying graphene composite, and the antioxidant. The antibacterial rates on escherichia coli and staphylococcus aureus of the antibacterial composite material are more than 90%. The antibacterial composite material can be applied to the electrical and electronic industry, automobile industry, instrument and meter industry, machinery industry and the building material industry.
