Description
Technical field
Master batch preparing technical field is used the invention belongs to macromolecular material is function modified, is related to one kind
Graphene oxide antibacterial matrices and its preparation method and application.
Background technology：
Anti-biotic material is that a class has antibacterial and bactericidal property new function material.Generally general
One or more specific antimicrobial components are added in logical material to be obtained.Common material is provided with antibacterial
Property after, the various products being made up of them are provided with sanitary cleaning function, to protect it is healthy,
Disease is reduced, can be played an important role.Antibiotic plastic and anti-bacterial fibre as in anti-biotic material most
It is noticeable branch, it is quite varied using field, with important research and application value.
The development and application of antibacterial matrices has turned into the important technology content of the development field.
At present, conventional antiseptic includes inorganic, organic and natural bio-antimicrobial agents three major types type,
Wherein inorganic antiseptic is based on the nano composite anti-biotic material of novel photocatalysis type and load silver
Will, organic antibacterial agent is then specially imitated in the antibiotic property of biomolecule such as microbial metabolism enzyme etc. with exploitation
Be its expand direction, natural bio-antimicrobial agents can derive from all organisms, mainly including polysaccharide,
Polypeptide and glycopeptide polymer-like substances.Different antiseptics has different resisting to same pathogeny bacterium
The bacterium mechanism of action and validity, same antiseptic also have different resisting for different pathogeny bacterium
The bacterium mechanism of action and suppress scope, therefore obtain not only long-acting but also wide spectrum, not only efficient but also safe anti-
Microbial inoculum, the processing and use to anti-biotic material is particularly significant.
Graphene oxide (GO) is the important derivative of Graphene, with sp2The individual layer of hydridization
There is the oxygen containing functional group such as substantial amounts of carboxyl, hydroxyl, epoxy radicals on atomic structure, its surface,
These functional groups impart for example good dispersiveness of graphene oxide numerous characteristics, hydrophily and
With the compatibility of some polymer etc., this can assign material more chemical reactivities,
Adjacent layer can be made to form the interaction force that network structure improves monolithic interlayer by crosslinking, so that
Improve the physical property of material.With the development of GO functional methods, difference in functionality it is oxygen-containing
Group assigns the more potential advantages of GO, and it also begins to increase in the application of antibiosis.

The preparation process of graphene oxide antibacterial matrices of the present invention is：Matrix resin is existed
Dried to water content in the range of 105-120 DEG C and be less than 0.3%, then by the content and oxidation stone
Black alkene powder, dispersant are sufficiently mixed, common through double screw extruder in the range of 200-280 DEG C
Mixed, extrusion, granulation, are made the antibacterial matrices containing graphene oxide powder.
Graphene oxide antibacterial matrices of the present invention can be applied in fresh-keeping material, sanitary material
The fields such as material, ornament materials, non-woven fabrics, textile garment, it is female using the graphene oxide antibacterial
The obtained product of grain has good antibacterial effect to Escherichia coli and staphylococcus aureus.
The present invention compared with prior art, its process is simple, it is easy to operate, and yield is high, into
This low, antibacterial effect of the graphene oxide anti-biotic material of preparation, according to QB/T2591-2003
《Antibiotic plastic Anti-microbial Performance Tests method and antibacterial effect》And GB/T20944.1-2007《Spin
The evaluation part 1 of fabric anti-microbial property：Agar diffusion method》Method is tested, and has been reached anti-
The good grade of bacterium effect, can be applicable to fresh-keeping material, hygienic material, ornament materials, nothing
Spin the fields such as cloth, textile garment.
