Embodiment 1

[0008] Example 1: Mix carbon nanotubes with a diameter of less than 60nm and ethanol to form a solution of 5 grams of carbon nanomaterials per liter, and use an ultrasonic oscillator to fully disperse it, then immerse medical mesh gauze in the solution for several minutes, and take out Dry; or apply the solution evenly on the medical mesh gauze with a brush, and dry the gauze to isolate and kill viruses and bacteria. The medical gauze modified with carbon nanomaterials is placed inside the mask to make a medical mask with high-efficiency disinfection and sterilization functions.

Embodiment 2

[0009] Example 2: Mix the mixture of carbon nanotubes and carbon nanofibers with distilled water to form a solution of 20 grams of carbon nanomaterials per liter, and stir to make it fully dispersed, then soak the cotton cloth in the solution for several minutes, take it out and dry it to obtain Cotton fabric that isolates, kills viruses and bacteria. Cotton fabrics modified with carbon nanomaterials can be made into protective clothing.

Embodiment 3

[0010] Example 3: Mix carbon nanofibers with a diameter below 300nm and acetone to form a solution of 15 grams of carbon nanomaterials per liter, and use an ultrasonic oscillator to fully disperse it, then immerse the mesh gauze in the solution for several minutes, take it out and dry it ; Or apply the solution evenly on the mesh gauze with a brush, and dry to obtain the desired cotton fabric. The above-mentioned gauze modified with carbon nanomaterials is pasted on the air conditioner filter net to make a carbon nanomaterial modified air conditioner filter net with high-efficiency disinfection and sterilization functions.

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 [0001] The invention relates to the use of carbon nanometer materials, especially suitable for isolating and killing severe viruses and / or bacteria. Background technique [0002] Carbon nanomaterials are a new type of carbon material newly discovered in the early 1990s, mainly including carbon nanotubes with diameters below 100nm (mostly between 10-60nm) and carbon nanotubes with diameters below 500nm (mostly between 20-300nm Between) carbon nanofibers, the length of which can reach tens or hundreds of microns. Due to its unique structural characteristics, it has unusual physical, chemical and mechanical properties, etc., and is considered to be used in one-dimensional conductors, super composite materials, superhard materials, hydrogen storage materials, catalysts and catalyst supports, and high-efficiency adsorbents. , microwave-absorbing materials and other fields have broad application prospects, and have been paid attention by many researchers. However,...
