Abstract
An application of the nano carbon material in killing bacteria and viruses including SARS virus is disclosed. The said nano carbon material has a great deal of active surface atoms, which can adsorb the size comparable bacteria and viruses to change their shapes and internal tissues for killing them.
Description
Technical field
The present invention relates to the purposes of carbon nanomaterial, especially be applicable to isolation, kill potent virus and/or bacterium.
Background technology
Carbon nanomaterial is newfound a kind of novel carbon materials of early 1990s, mainly comprise diameter at the carbon nanotube of (most between the 10-60nm) below the 100nm and the diameter carbon nanofiber (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 property etc., be considered to having broad application prospects in fields such as one dimension transmitter, superpower matrix material, superhard material, hydrogen storage material, catalyzer and support of the catalyst, 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 provides a kind of purposes of carbon nanomaterial, is about to carbon nanomaterial and is used for isolation, kill bacteria and/or virus.
Technical scheme provided by the invention is: carbon nanomaterial is used for isolation, kill bacteria and/or virus.
Above-mentioned carbon nanomaterial is the mixture of carbon nanotube, carbon nanofiber or carbon nanotube and carbon nanofiber.
Because a key property of carbon nanomaterial is that it has specific activity carbon material " bigger specific surface area " and " stronger activity ".Our preliminary medical sterilization experiment shows that it has the human body of killing or animal body outside, the effect of especially airborne bacterium and virus.
The sterilization mechanism of carbon nanomaterial is: utilize the very high surfactivity 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 intravital atom, 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 unsteady 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 steady state.This surfactivity 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 and virus.
Embodiment
Embodiment 1: with diameter be carbon nanotube 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 solution evenly is coated on the medical netted gauze the dry gauze that must isolate, kill virus and bacterium with hairbrush.Hospital gauze seam after will handling with the carbon nanomaterial modification places mouth mask inside, can be made into the medical mask with high-efficiency steriliging function.
Embodiment 2: with the carbon nanotube and the mixture of carbon nanofiber mix with distilled water be made into 20 the gram carbon nanomaterials/liter solution, and stirring fully disperses it, then cotton was immersed in the solution several minutes, take out be drying to obtain the cotton fabric of isolating, killing virus and bacterium.Cotton after handling with the carbon nanomaterial modification is weaved cotton cloth and can be made into protective clothing.
Embodiment 3: with diameter be carbon nanofiber 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.It is online that above-mentioned gauze after handling with the carbon nanomaterial modification is pasted on air-conditioner filtering, can be made into the carbon nanomaterial modification air-conditioning filter net with high-efficiency steriliging function.
Claims (2)
1. the purposes of a carbon nanomaterial is used for isolation, kill bacteria and/or virus with carbon nanomaterial.
2. purposes according to claim 1 is characterized in that: above-mentioned carbon nanomaterial is the mixture of carbon nanotube, carbon nanofiber or carbon nanotube and carbon nanofiber.
