Abstract

The invention discloses an efficient antibacterial and antivirus copper-based filter screen with a hierarchical structure and a preparation method. The antibacterial copper-based filter screen is composed of a copper screen skeleton, a Cu (OH) 2 nanorod array growing on the surface of a copper screen, a Cu-based metal organic framework (Cu-BDC MOF for short, copper-terephthalic acid) array growingon the surfaces of Cu (OH) 2 nanorods, and a visible light photocatalyst loaded on the surface of Cu-BDC MOF. The production comprises four steps of copper net surface pretreatment, preparation of asurface modifier, preparation of a metal organic framework and loading of the nano visible light photocatalytic material. The efficient antibacterial and antivirus copper-based filter screen with thehierarchical structure, disclosed by the invention, can effectively inactivate bacteria, viruses and the like, ensures cleanness of an environmental water source and domestic water, ensures human health, and can be applied to the fields of protective masks, air purification, water disinfection and the like.

Description

technical field

[0001] The invention relates to the field of environmental protection materials, in particular to the fields of air purification, water purification and antibacterial functions. Background technique

[0002] With the continuous development of the times, people's living standards continue to improve, but in recent decades, there have been many airborne diseases, and the unclean living water has caused the lady's physical discomfort. Therefore, people are eager to develop some technologies to make Air and domestic water are safe and reliable.

[0003] Copper and copper ions have a long history of being used as antibacterial agents. They are a broad-spectrum inorganic antibacterial and antiviral material. Their anti-kill mechanisms to microorganisms are: a. Destroy cell membranes and induce protein denaturation through contact reactions; b. Generate reactive oxygen species to inhibit live killing microorganism. The current copper-based antibacterial and disinf...
