Problems solved by technology

However, since the unmodified original graphene is inert on the surface, and its size is at the nanoscale, it is prone to agglomeration, and it is difficult to effectively disperse and compound with the fabric matrix, which makes the binding force between graphene and the fabric matrix poor. The physical fastness of the item is not high, which seriously affects the antibacterial and antiviral durability of the fabric

Embodiment 1

[0040] A graphene nanosheet antibacterial and antiviral fabric with a special-shaped structure edge, comprising a polyester-cotton fabric and small sheet graphene nanosheets (such as figure 1 shown). The loading capacity of the small sheet graphene nanosheets is 2.5wt%; the lateral dimension of the small sheet graphene nanosheets is 12nm, the thickness is about 2nm, the heteroatom content is about 1wt%, and the defect density ID / IG is about 0.01.

[0041] The small-sheet graphene nanosheets are loaded onto the polyester-cotton fabric through the post-finishing method, that is, the small-sheet graphene nanosheets are prepared into a slurry with a content of 10wt% by ultrasonic dispersion, and the slurry also includes Dispersant, wetting agent, coupling agent and other additives, the solvent is deionized water; then use a mixed solvent of polar solvents such as N,N-dimethylformamide and low boiling point solvents such as acetone or ethanol to treat polyester-cotton fabrics Car...

[0049] A graphene nanosheet antibacterial and antiviral fabric with a special-shaped structure edge, compared with Example 1, the difference is that it includes a polyester-cotton fabric and a small sheet of graphite with a zigzag structure edge loaded on the polyester-cotton fabric ene nanosheets. The loading capacity of the small sheet graphene nanosheets is 5wt%; the lateral size of the small sheet graphene nanosheets is 15nm, the thickness is about 2nm, the heteroatom content is about 1.5wt%, and the defect density ID / IG is about 0.01. Others are substantially the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a graphene nanosheet antibacterial and antiviral fabric with a special-shaped structure edge. The fabric is treated and modified by adopting a small-sheet-layer graphene nanosheet with a special-shaped structure edge in a pointed shape or a sawtooth shape and with the transverse size smaller than 100nm and the thickness smaller than 10nm. The small and sharp edge is endowedby utilizing a longitudinal ultrathin structure, a transverse nanoscale size and the pointed or sawtooth-shaped structure edge of the small-sheet-layer graphene nanosheet, and when the small-sheet-layer graphene nanosheet is in contact with bacteria or viruses, cell walls of micron-scale germs can be instantly punctured to cause death or protein films of nanoscale viruses can be punctured, so thatreplication of the viruses is inhibited, and finally the purposes of inhibiting bacteria of various germs and resisting viruses are achieved. The small-sheet-layer graphene nanosheet with the special-shaped structure edge and a large-sheet-layer graphene nanosheet are combined for use, and the small sheet layer can serve as a stripping agent of large-sheet-layer graphene, so that agglomeration isreduced, and efficient antibacterial and antiviral effects of the fabric are achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-virus fabrics, and relates to a graphene nanosheet antibacterial and anti-virus fabric with irregular structure edges. Background technique [0002] Graphene is carbon atoms with sp 2 The hexagonal honeycomb two-dimensional nanomaterial composed of hybrid orbitals can be regarded as a single-layer graphite sheet. In recent years, the antibacterial function of graphene and its derivatives has been researched and verified by the industry. Researchers believe that its antibacterial principle lies in the fact that when micron-sized bacteria walk on the sharp nano-scale two-dimensional material of graphene, the cell wall is cut instantly And die. In addition, graphene can also destroy cell membranes and kill bacteria through large-scale direct pumping of phospholipid molecules on cell membranes. [0003] At present, the antibacterial properties of graphene have been applied to underwear, socks, bedding...
