Embodiment 1

[0049] (1) Preparation of conductive polymer surface treatment agent based on conductive polymer PEDOT-PSS.

[0050]

[0051] In percent by weight, the raw material consists of:

[0052]

[0053] Add 100mL of deionized water and 1.30g of PSS-Na (sodium polystyrene sulfonate) into a three-neck round bottom flask, stir rapidly at room temperature to fully disperse it. Add 0.26g of EDOT (3,4-ethylenedioxythiophene) dropwise with a micro-injection pump. After the dropwise addition, stir rapidly for about 5 minutes. Then add 0.60g (NH 4 ) 2 S 2 o 8 , add 0.05g of ferric sulfate under rapid stirring, continue to stir for 5min, adjust the pH of the reaction solution with 10% dilute hydrochloric acid to keep it at about 2, and the reaction solution gradually turns blue ink. After continuing to react for 20 h, a dark blue PEDOT-PSS aqueous dispersion was obtained as a raw material for the next step.

[0054] Add a certain amount of PEDOT-PSS aqueous dispersion into the cont...

Embodiment 2～7

[0066] The proportions of each component were changed, and the rest of the method was the same as in Example 1. The influence of the anti-smog effect of window screen fibers made of conductive polymer surface treatment agents of different proportions was investigated. The specific proportions are shown in Table 2.

Abstract

The invention discloses an anti-haze window screen fiber based on conductive macromolecules, and a preparation method and an application thereof. The anti-haze window screen fiber comprises a fiber and a conductive macromolecule surface treatment agent layer attached on the surface of the fiber; a conductive macromolecule surface treatment agent is composed of a PEDOT-PSS aqueous dispersion body, waterborne polyurethane, 3-(2,3-epoxypropoxy)propyl trimethoxy silane, isopropanol, 1-methyl-2-pyrrolidone, a hydroxyethyl cellulose aqueous solution, a waterborne flatting agent BYK-333 and N,N-dimethylethanolamine. The invention also discloses the preparation method and application of the anti-haze window screen fiber. A screen window is prepared by the anti-haze window screen fiber based on the conductive macromolecules, and in the premise of not affecting a ventilation effect, the blocking rate of PM2.5 is enhanced; and the preparation method is simple, and the product has high repeatable use rate.

Description

technical field [0001] The invention relates to window screen fibers, in particular to a conductive polymer-based anti-haze window screen fiber and its preparation method and application. Background technique [0002] Smog is a general term for fog and haze, a weather phenomenon, and a general expression of the excessive content of various suspended particles in the atmosphere. Refers to a large number of extremely fine dry dust particles such as dust, sulfuric acid, nitric acid, and organic hydrocarbons in the air floating in the air evenly, making the air turbid, blurring the vision and leading to deterioration of visibility. Haze weather is a state of air pollution, and haze, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered to be the "culprit" of haze weather. In recent years, with the gradual deterioration of air quality, the frequency of smog weather phenomena has become higher and higher. The...
