Problems solved by technology

[0002] Solar energy has been widely used as a clean energy source. Among the current photothermal conversion materials, carbon materials have attracted extensive attention because of their good light absorption coefficient, high stability, and excellent photothermal performance. However, due to their Carbon materials with high brittleness, difficulty in film formation, and excellent performance are expensive and difficult to produce, thus limiting the practical application of light-to-heat conversion materials based on carbon materials

Embodiment 1

[0021] Example 1: Preparation method of airgel-polypyrrole photothermal conversion material

[0022] The method includes the following steps:

[0023] Step 1) synthesis of chitosan airgel

[0024] 1.1 Measure 3ml 1.5wt% chitosan solution, 1ml 5wt% PVA and 150uL glutaraldehyde into a clean small beaker in sequence (the mass ratio of chitosan, polyvinyl alcohol and glutaraldehyde is 1.2:1.33:1) .

[0025] 1.2 Add a clean magnet and stir magnetically for 30 minutes at room temperature.

[0026] 1.3 Put it into the freezer and freeze-dry for 36 hours.

[0027] Step 2) in situ polymerization

[0028] 2.1 Add 2.349g of FeCl 3 ·6H 2 O was dissolved in 18 mL of deionized aqueous solution and kept stirring until completely dissolved to obtain FeCl 3 solution.

[0029] 2.2 Place chitosan airgel in 3ml FeCl 3 Completely infiltrate the solution, then add 0.5ml of freshly distilled pyrrole (the mass ratio of pyrrole to chitosan airgel is 1:0.265), seal it with plastic wrap, and le...

Abstract

The invention discloses a preparation method and application of an aerogel-polypyrrole photo-thermal conversion material. Chitosan and PVA are used as substrates; the aerogel-polypyrrole photo-thermalconversion material is obtained by preparing chitosan aerogel, adding pyrrole, carrying out in-situ polymerization on FeCl3 and uniformly attaching the FeCl3 to the chitosan aerogel, the aerogel-polypyrrole photo-thermal conversion material is stable in structure, has excellent hydrothermal conversion performance and light absorption performance, can be used as a photo-thermal conversion material, and is applied to occasions such as sea water desalination and sewage treatment.

Description

Technical field: [0001] The invention relates to a preparation method and application of an airgel-polypyrrole photothermal conversion material. Background technique: [0002] Solar energy has been widely used as a clean energy source. Among the current photothermal conversion materials, carbon materials have attracted extensive attention because of their good light absorption coefficient, high stability, and excellent photothermal performance. However, due to their Carbon materials with high brittleness, difficulty in film formation, and excellent performance are expensive and difficult to produce, thus limiting the practical application of light-to-heat conversion materials based on carbon materials. Invention content: [0003] The purpose of the present invention is to provide a preparation method and application of an airgel-polypyrrole photothermal conversion material, using chitosan and PVA as a base to prepare chitosan airgel, add pyrrole, and use FeCl 3 Make it in...
