Example Embodiment
[0028] Example 1:
[0029] The syringe includes a barrel and a dispensing needle,
[0030] See Figure 1 to Figure 3 As shown, an antibacterial high-efficiency air filtration membrane of this embodiment includes a substrate and a composite nanofiber layer, the composite nanofiber layer covers the substrate, and the composite nanofiber layer is completely tightly attached to the substrate. The composite nanofiber layer is woven from at least three materials, the composite nanofiber layer presents a bead string structure, and the shape of the beads is spherical, ellipsoidal, spindle-shaped or elongated spindle-shaped; The average width is 200-2000nm, and the average length is 500-3000nm. The air filter membrane in this embodiment has a double-layer structure.
[0031] In this embodiment, the substrate is a non-woven fabric, and its material is one or more of polypropylene, polyacrylonitrile, polyethylene and the like. The composite nanofiber layer is covered on the substrate by an ...
