Abstract

Disclosed is a nanosilver wire polymer compound antibacterial product comprising a nanosilver wire layer, a nanosilver particle layer, a first polymer layer, a second polymer layer and a third polymer layer which are sequentially stacked. The nanosilver wire polymer compound antibacterial has the advantages that the antibacterial product is obtained through one-step forming by polymerizing a macromolecular prepolymer on the nanosilver wire layer in situ, and nanosilver wires are closely combined with the polymer, so that the antibacterial product is lasting in antibacterial effect and free of shedding; by using a preparation method of the nanosilver wire polymer compound antibacterial product, consumption is reduced, large-area and industrialized production is easy to realize, and the preparation process is easier to adjust and control.

Description

technical field [0001] The invention relates to the technical field of antibacterial product production, in particular to a nano-silver wire polymer composite antibacterial product and a preparation method thereof. Background technique [0002] In the 21st century, people pay more and more attention to the living environment around them. Antibacterial materials refer to a new class of functional materials that have the function of killing or inhibiting microorganisms.
