Abstract

The invention provides a graphene composite antibacterial master batch as well as a preparation method and application thereof. The graphene composite antibacterial master batch is prepared from the following raw materials in specific parts: silver-plated graphene quantum dots, a polymer matrix, dopamine and polyvinylpyrrolidone. The silver-plated graphene quantum dots are added into the polymer matrix, so that the graphene composite antibacterial master batch has antibacterial and antiviral effects. Furthermore, dopamine and polyvinylpyrrolidone are jointly selected as dispersing agents and generate a synergistic effect, so that the dispersity of the silver-plated graphene quantum dots in the polymer matrix and the compatibility of the silver-plated graphene quantum dots and the polymer matrix are improved, and the antibacterial property, the antiviral property and the mechanical property of the graphene composite antibacterial master batch are further improved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a graphene composite antibacterial masterbatch and a preparation method and application thereof. Background technique [0002] High molecular polymers have the advantages of non-toxicity, light weight, good mechanical properties, corrosion resistance, easy processing and recycling, etc., and are widely used in daily life, such as kitchen utensils, toilet facilities, trash cans, plastic shells of household appliances, Wallpapers, food packaging bags, etc. However, as people's awareness of health and environmental protection becomes stronger and stronger, polymer materials themselves can no longer meet people's needs, so they need to be modified to endow them with other special properties, such as flame retardancy and antistatic properties. , softness and so on. Modification methods include chemical modification and physical modification. The so-called che...
