Abstract
The making process includes mixing nano carbon material and volatile solvent to compound solution with dispersed nano carbon material of 3-50 g in each liter, soaking cotton gauze in the solution or brushing the solution to the cotton gauze, and drying to obtain the cotton fabric. The cotton fabric has virus and bacteria killing function greatly higher than that of other active carbon material. The present invention adopts fibrous carbon nano material, which is twisted to cotton fabric and has great adhesion, high durability and other advantages compared with granular carbon nano material and other kind of carbon nano material.
Description
Technical field
The COTTON FABRIC that the present invention relates to a kind of isolation, kills virus and/or bacterium especially is applicable to isolation, kills potent virus and bacterium.
Background technology
At present, common medical mask generally only plays the effect of isolating dust, bacterium and virus, the not effect of killing bacteria or virus, and also its filter effect is relatively poor.Different as requested, be made generally in which floor or ten multilayers, yet along with the increase of thickness, its comfortable wearing reduction is unfavorable for wearing for a long time etc.At present, occurred the mouth mask that active carbon material is made on the market, its major function is to utilize the strong suction-operated of activated carbon, reaches the effect of killing bacteria and virus, and price is 2 times of common mouth mask approximately, and harder, and comfortable wearing is relatively poor.
For potent virus or bacterium (as SARS virus), medical personnel must wear the protective clothing of thick and heavy and gas permeability difference usually and wear multilayer or a plurality of mouth mask.Bring great inconvenience not only for medical personnel's work, and its poor effect.
Carbon nanomaterial is newfound a kind of novel carbon materials of early 1990s, mainly comprise diameter at the CNT of (most between the 10-60nm) below the 100nm and the diameter carbon nano-fiber (most between 20-300nm) below the 500nm, its length can reach tens of or hundreds of microns.Because its particular structure feature, make it have unusual physics, chemistry and mechanical performance etc., be considered to having broad application prospects in fields such as one dimension transmitter, superpower composite, superhard material, hydrogen storage material, catalyst and catalyst carrier, high-efficiency adsorbent, absorbing materials, be subjected to the attention of Many researchers, yet, kill virus and bacterium aspect application yet there are no report.
Summary of the invention
Technical problem to be solved by this invention provide a kind of have bacterium or virus are had the COTTON FABRIC of isolation, killing effect.
Technical scheme provided by the invention is: a kind of isolation, the COTTON FABRIC of killing virus or bacterium, its key are to be attached with carbon nanomaterial on the COTTON FABRIC.
Above-mentioned carbon nanomaterial is the mixture of CNT, carbon nano-fiber or CNT and carbon nano-fiber.
Above-mentioned COTTON FABRIC is cotton gauze or cotton.
The present invention also provides above-mentioned isolation, has killed the preparation method of the COTTON FABRIC of virus or bacterium, carbon nanomaterial and volatile solvent are made into 3～50 gram carbon nanomaterials/rise solvent strength solution, and carbon nanomaterial is scattered in the volatile solvent, then the netted gauze of COTTON FABRIC is immersed in the solution of above-mentioned preparation, or with hairbrush with the preparation solution be coated on the COTTON FABRIC, be drying to obtain required COTTON FABRIC.
Can adopt ultrasonic oscillation device or mechanical agitation that carbon nanomaterial is scattered in the volatile solvent.
Above-mentioned volatile solvent is ethanol (alcohol), methyl alcohol, acetone or water etc.
Above-mentioned isolation, the COTTON FABRIC of killing virus or bacterium can be used for the protective articles making isolation such as protective clothing, mouth mask, air-conditioning filter net, kill virus and/or bacterium.
Because a key property of carbon nanomaterial is that it has specific activity material with carbon element " bigger specific area " and " stronger activity ".Our preliminary medical sterilization experiment shows that it has the effect of stronger killing bacteria and virus.
The sterilization mechanism of carbon nanomaterial is: utilize the very high surface-activity of carbon nanomaterial, the atomicity that promptly is positioned at the carbon nanomaterial surface is compared with its whole atomicity, shared large percentage, the behavior of surface atom will be played conclusive effect to the performance of material like this.Compare with the atom in the body, the characteristics of surface atom are to have " dangling bonds " that is not connected with other atom, and in other words, it is in a kind of labile state of higher-energy.Therefore, its as easy as rolling off a log with external other atom or material combines, so that it is in more low-energy stable state.This surface-activity by carbon nanomaterial can be adsorbed on its surface with bacterium suitable with its scale size or virus, changes the body or the internal organizational structure of bacterium or virus then, reaches the purpose of killing bacteria or virus.
The present invention has following advantage:
1) because carbon nanomaterial has bigger surface-activity, its killing bacteria and the function of killing the virus are much higher than other active carbon material;
2) compare with the nano material of other granular active carbon material and type, of the present inventionly be fibrous carbon nanomaterial, have strong adhesion, advantage such as durable in use by the weave cotton cloth winding of fiber of cotton;
3) used carbon nanomaterial can be bought on market;
4) preparation section of the present invention is simple, need not special technology and equipment.
The specific embodiment
Embodiment 1: with diameter be CNT below the 60nm mix with ethanol be made into 5 gram carbon nanomaterials/liter solution, and it is fully disperseed with the ultrasonic oscillation device, then will medical netted gauze immerse in the solution taking-up drying several minutes; Or with hairbrush solution evenly is coated on the medical netted gauze, be drying to obtain required COTTON FABRIC.
Embodiment 2: with the CNT and the mixture of carbon nano-fiber mix with distilled water be made into 20 gram carbon nanomaterials/liter solution, and stir it fully disperseed, then cotton was immersed in the solution several minutes, take out dry; Or with hairbrush solution evenly is coated on the cotton, be drying to obtain required COTTON FABRIC.
Embodiment 3: with diameter be carbon nano-fiber below the 300nm mix with acetone be made into 15 gram carbon nanomaterials/liter solution, and it is fully disperseed with the ultrasonic oscillation device, then netted gauze was immersed in the solution several minutes, take out drying; Or with hairbrush solution evenly is coated on the netted gauze, be drying to obtain required COTTON FABRIC.
Embodiment 4: above-mentioned dressing scissors after handling with the carbon nanomaterial modification is cut into a certain size, and it is online to be pasted on air-conditioner filtering, promptly makes the carbon nanomaterial modification air-conditioning filter net with high-efficiency steriliging function.
Embodiment 5: the hospital gauze after will handling with the carbon nanomaterial modification is cut into a certain size, and seam places mouth mask inside, promptly makes the medical mask with high-efficiency steriliging function.
Embodiment 6: the cotton after will handling with the carbon nanomaterial modification is weaved cotton cloth and makes protective clothing.
