preparation example Construction

[0032] The organic polymer material is preferably prepared into a thin film, and the membrane structure can increase the specific surface area and increase the probability of trapping bacteria in the air. The preparation method of the polymer film is, for example, an electrostatic spinning method, a melt stretching method, a uniaxial stretching method or a biaxial stretching method.

[0033] The self-sterilizing metal particles 102 shown in the embodiment of the present invention are metal particles that achieve a sterilization effect. The metal or metal ions that can be released by the self-sterilizing metal particles 102 incorporated in the triboelectric material play a bactericidal effect, and the released metal ions may include silver ions, copper ions, zinc ions, nickel ions, aluminum ions, and divalent iron. Ion, magnesium ion, calcium ion, barium ion, manganese ion and tin ion, or a combination of any two or more of the above ions. The self-sterilizing metal particles 102...

Embodiment 1

[0051] Cut a long acrylic board support with a size of 100×10×5mm and a gasket with a size of 10×10×0.8mm, stick a copper foil with a thickness of 0.06mm on the surface of the support tightly, and paste the gasket tightly on At both ends of the copper foil, a nylon film with a size of 100×10×0.03mm doped with 0.01% silica / silver particles is placed between the copper foils pasted with gaskets, and finally the two End fixed.

[0052] Figure 5a with Figure 5b They are respectively the output voltage diagram and output current diagram when the self-sterilizing flexible friction material of the present invention is used in a friction nanogenerator driven by wind energy. When the triboelectric generator is placed in an environment with a wind speed of 12m / s, the self-sterilizing flexible friction material vibrates up and down and periodically contacts the copper foil due to the triboelectric effect and electrostatic induction to generate electrons. The output voltage of the triboel...

Embodiment 2

[0055] Cut a long acrylic board support with a size of 100×10×5mm and a gasket with a size of 10×10×0.8mm, stick a copper foil with a thickness of 0.06mm on the surface of the support tightly, and paste the gasket tightly on At both ends of the copper foil, a nylon film with a size of 100×10×0.03mm doped with 0.03% silica / silver particles is placed between the copper foils with gaskets, and finally the two End fixed.

[0056] After testing, the nylon membrane doped with 0.03% silica / silver particles can kill 99% of Staphylococcus aureus in the environment.

[0057] Through the above embodiments, the problem of the single function of the friction material is solved. It not only has the function of the traditional friction material, but also can realize the function of killing germs, and realizes the multifunctionality of the friction material. The self-sterilizing friction material of the embodiment of the present invention can be used for air purification and friction nano generat...

Description

Technical field [0001] The present invention relates to the field of friction nano power generation and air purification, and further relates to a self-sterilizing friction material, and a friction nano generator and an air purification device containing the friction material. Background technique [0002] Bacteria are ubiquitous in the nature on which humans live, such as Staphylococcus aureus, which can be found in air, water, and dust. Human infections caused by it occupy the second place, second only to E. coli. The nasal infection rate of patients with upper respiratory tract infection is 83%, and severe cases can cause Staphylococcus aureus pneumonia. At the same time, Staphylococcus aureus mainly contaminates food. When people eat contaminated food, they will be infected, resulting in food poisoning. Therefore, food processing companies have very high requirements for workshops. How to control the bacteria in the air of the workshop is a problem that must be faced. And...
