This invention discloses an antibacterial filter, its preparation method, and its application, relating to the field of
air purification. The antibacterial filter disclosed in this invention uses
glass fiber as a substrate, and is prepared by loading a nano-
copper-carbon composite through
hydroxylation pretreatment and
hydrothermal reaction. The resulting antibacterial filter exhibits excellent bacterial capture rate and antibacterial performance. The
glass fiber used in this invention has a
large pore size, allowing the antibacterial filter to capture
bacteria without increasing air resistance or reducing pressure drop, i.e., it is not easily clogged. The
oxygen-rich nano-carbon in the nano-
copper-carbon composite increases the
surface roughness of the
glass fiber. This increased roughness, combined with the active groups on the surface of the
oxygen-rich nano-carbon, significantly improves the bacterial capture rate of the antibacterial filter. The nano-
copper in the nano-copper-carbon composite provides excellent antibacterial properties.
