The invention provides a kind of film, it includes a coating and a Static Spinning basic unit, the coating contain by oxycellulose microfibre prepare it is cellulose nano-fibrous, the coating is coated in the Static Spinning basic unit.The diameter of the nanofiber of the Static Spinning basic unit is bigger than cellulose nano-fibrous diameter.The film also has a nonwoven support layer, and the Static Spinning basic unit is placed on the nonwoven support layer.The diameter of the microfibre of nonwoven support layer is more than the diameter of the nanofiber of the Static Spinning basic unit.Static Spinning film is applied in microfiltration field, and cellulose nano-fibrous membrane is used for ultrafiltration, nanofiltration and counter-infiltration after being chemically modified. |
