Embodiment 1

[0059] In a 50ml beaker, dissolve 1.2g of ammonium persulfate (purchased from Aladdin) in 10ml of deionized water to prepare a 120mg / ml ammonium persulfate aqueous solution, and pass the obtained ammonium persulfate aqueous solution through a pipette Add it dropwise to a dust-free paper (0609D dust-free paper) with a diameter of 5 cm until the entire dust-free paper is wetted by ammonium persulfate aqueous solution.

[0060] Then, spread the wetted dust-free paper on the smooth and flat surface of the ice cube, and then add pyrrole (purchased from Aladdin Company) drop by drop on the dust-free paper through a pipette to carry out the polymerization reaction , After 1 min, the surface of the dust-free paper can be seen to be blackened (that is, covered with a black layer), indicating that the polymerization reaction is completed.

[0061] Use tweezers or hands to remove the dust-free paper covered with a black layer from the ice cube, wash it twice with deionized water, and the...

Embodiment 2-5

[0063] Carry out the experiment in a manner similar to Example 1, the difference is that the 1-layer two-dimensional conductive polymer solar light absorber obtained by drying in Example 1 is used as a substrate, and the polymerization and The drying steps were repeated 1, 3, 4 and 6 times respectively to obtain 2-layer, 4-layer, 5-layer and 7-layer two-dimensional conductive polymer solar light absorbers (referred to as 2-layer polymer and 4-layer polymer respectively). , 5-layer polymer and 7-layer polymer).

Embodiment 6

[0073] In a 500ml beaker, by dissolving 1.2g ferric chloride powder (purchased from Aladdin Company) in 10ml hydrochloric acid (purchased from Sinopharm Reagent Company; concentration 36%), a mixed solution of ferric chloride hydrochloric acid was obtained, and the obtained The mixed solution was added dropwise to a qualitative filter paper with a diameter of 5 cm (purchased from Sinopharm Reagent Company) through a pipette until the entire qualitative filter paper was wetted by the mixed solution.

[0074] Then, spread the wetted qualitative filter paper on the smooth ice cube surface, then add pyrrole (purchased from Aladdin Company) drop by drop on the qualitative filter paper by pipette to carry out the polymerization reaction. After 2 minutes, the surface of the qualitative filter paper can be seen to be blackened (that is, covered with a black layer), indicating that the polymerization reaction is completed.

[0075] With tweezers or hands, the qualitative filter paper c...

Abstract

The invention provides a preparing method for a two-dimensional conductive polymer sunlight absorber used for solar water vapor evaporation. The preparing method comprises the steps that under the presence of an oxidizing agent and a solvent or under the presence of a solution formed by the oxidizing agent and the solvent, pyrrole is subjected to polymerization reaction on a porous sheet-shaped carrier at the temperature of (-5)-5 DEG C, then drying is conducted, and thus the required two-dimensional conductive polymer sunlight absorber is formed. The two-dimensional conductive polymer sunlight absorber, especially a multi-layer two-dimensional conductive polymer sunlight absorber, prepared through the preparing method has the good sunlight capture capability, the excellent water vapor evaporation capability and outstanding stability and flexibility; and in addition, the two-dimensional conductive polymer sunlight absorber prepared through the preparing method has outstanding industrialization prospects in the aspects of seawater desalination and sewage treatment.

Description

technical field [0001] The invention relates to the technical field of solar water vapor evaporation, in particular, the invention provides a method for preparing a two-dimensional conductive polymer solar light absorber for high-efficiency solar water vapor evaporation. Background technique [0002] Water is the source of life and the basis for the survival and development of all living organisms. Although 71% of the Earth's surface area is covered by water, this is mostly salt water, with only 2.5% fresh water. And this fresh water is mainly in the form of glaciers and groundwater, all lakes, rivers and swamps add up to only 0.3% of the earth's total fresh water reserves. And our country is a serious water shortage country. my country's total fresh water resources are 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world. However, my country's per capita water resources are only 2,300 cubic meters, only 1 / 4 of the world's av...
