Embodiment 1

[0042] Take 10mL of butyl acrylate, 25μL of polyethylene glycol diacrylate, 1.4g of lithium bistrifluoromethanesulfonimide, and 0.14g of 1-hydroxycyclohexyl phenyl ketone, and prepare a set of the same ratio at the same time. However, 10 mg of the precursor solution of the light-to-heat conversion material MXene was added, and the mixture was dispersed uniformly by ultrasonication for 15 minutes.

[0043] The PTFE mold presents a "concave" shape as a whole, and a release film is pasted on the bottom of the PTFE mold. At the same time, paste a diaphragm in the middle of the release film, bend the diaphragm into an "L" shape, the height of the diaphragm is greater than the height of the PTFE mold, and the diaphragm divides the groove of the PTFE mold into two parts. The bottom of the diaphragm is coated with a thin layer of silicone oil so that the "L"-shaped diaphragm is attached to the middle part of the release film.

Abstract

The invention discloses a photo-thermal ionic gel film as well as preparation and application thereof, and belongs to the field of flexible electronic and photo-thermal and thermoelectric functional materials. The photo-thermal power generation ionic gel film comprises two parts, wherein one part is an ionic gel film prepared from an acrylate monomer, a cross-linking agent, an ionic conductive filler and a photoinitiator through a photo-crosslinking reaction; and the other half is an ionic gel film formed by adding a photo-thermal conversion material into the ionic gel film. The two ionic gel films are obtained by adding various precursors into a mold and carrying out copolymerization reaction under the irradiation of an ultraviolet lamp. Under an illumination condition, the ionic gel film can form an internal temperature difference, so an internal potential difference is formed, and power generation is realized. The photo-thermal ion gel film provided by the invention has the advantages of simplicity in preparation, easiness in obtaining raw materials, convenience in large-scale production and the like.

Description

technical field [0001] The invention belongs to the fields of flexible electronics and photothermal and thermoelectric functional materials. More specifically, it belongs to photothermal ionogel film and its preparation method and application. Background technique [0002] With the increasing demand for energy, traditional fossil energy needs to seek new ways of energy acquisition due to its shortcomings such as high emissions, high pollution, and non-renewability. As a result, a series of clean energy acquisition methods such as solar power generation, geothermal power generation, and wind power generation have emerged, and the proportion of these new energy sources in the global energy supply ratio is also increasing. Among them, solar power generation is more and more recognized by people, and has become one of the main ways for human beings to obtain energy. At present, the devices that use solar energy to generate electricity mainly include dye-sensitized solar cells,...
