Problems solved by technology

However, the biggest disadvantage of these two methods is that the antibacterial agent on the surface of the fabric is very easy to fall off, and the antibacterial effect is obviously weakened after repeated washing, so it cannot be widely used in the field of life and medical treatment (Lu Longxi et al., Antibacterial effect of new silver-embedded fiber fabrics Performance research, Chinese Journal of Disinfection, 2017, 34 (3): 214-217; Li Ling et al., Investigation of bacterial contamination of ICU medical staff masks in tropical areas, Hainan Medicine, 2018, 10 (29): 1468-1469)
Moreover, the mask filter material prepared by textile method has uneven pore size, and microorganisms are easily leaked at the corners of the pore surface, which greatly reduces the effect of sterilization.
[0008] In order to solve the problem that the ventilation holes of current masks are not selective, the sterilization depends on the walls of the holes to block microorganisms or viruses, the aperture is too small to affect the ventilation effect, and the antibacterial agents that may be carried on the masks are not durable and toxic, especially the toxic antibacterial that falls off Agents may directly enter the human body to affect health and masks cannot be reused. The invention relates to a selectively permeable anti-virus thin layer material and its application in the field of anti-virus

Abstract

The invention relates to a selective permeation antiviral thin-layer material and application thereof in the antiviral field. The selectively permeable antiviral thin-layer material is characterized in that the selectively permeable antiviral thin-layer material is composed of a linear polymer, cyclodextrin group molecules, an end-capped polymer and metal ions, and the linear polymer penetrates through an inner cavity hydrophobic part of a cyclodextrin group. The high-efficiency antiviral thin layer passes through the following requirements: an immersion test and oscillation method detection show that the antibacterial rate of the thin layer after acting on staphylococcus aureus and escherichia coli for 18 hours is greater than 99.5%. The efficient antiviral thin layer can be used for antiviral and antibacterial insoles, medical protective clothing, medical mattresses, bed sheets, protective covers, drapes, refrigerator linings and table and chair protective pads in the civil, medicaland military fields.

Description

technical field [0001] The invention relates to a selectively permeable antiviral thin-layer material and its application in the antiviral field, in particular to an antiviral and antibacterial mask lining, insoles, and medical protective clothing that can be used in civil, medical, and military fields. , protective cover, refrigerator lining, table and chair protective pad, medical mattress, belong to the technical field of health protection. [0002] technical background [0003] Environmental microorganisms are key factors that cause respiratory infections and increase the morbidity and mortality of respiratory diseases. Environmental microorganisms such as bacteria, fungi, actinomycetes, viruses and lower algae are important components of air pollution. Environmental microorganisms will attach to the surface of air aerosol fine particles and stay in the air for a long time with the fine particles. As people breathe, environmental microorganisms will enter the lungs or i...
