Atmospheric water collection material with adjustable heat transfer efficiency as well as preparation method and application of atmospheric water collection material
The invention discloses an atmosphere water collection material with adjustable heat transfer efficiency and a preparation method and application thereof, and belongs to the technical field of atmosphere water collection, the preparation method comprises the following steps: dissolving and dispersing polyethylene glycol in a chitosan solution to obtain a moisture absorption type polymer solution; the preparation method comprises the following steps: fully infiltrating melamine foam into a moisture absorption type polymer solution, and then sequentially carrying out bidirectional freezing casting and freeze drying treatment, so that the moisture absorption type polymer forms an oriented lamellar structure in pores of the melamine foam, thereby obtaining the atmospheric water collection material. According to the invention, hygroscopic macromolecules polyethylene glycol and chitosan interact with melamine foam to prepare an oriented lamellar structure, so that not only can the polyethylene glycol macromolecules be prevented from leaking after absorbing water, but also the prepared atmospheric water collection material can be in mutual contact under applied strain to generate a new heat conduction path; and the heat transfer efficiency is adjusted, so that the capability of quickly releasing water is obtained.
本发明公开了一种热传输效率可调的大气集水材料及其制备方法和应用，其属于大气集水技术领域，其中，该制备方法包括以下步骤：将聚乙二醇溶解分散在壳聚糖溶液中，得到吸湿型高分子溶液；将三聚氰胺泡沫充分浸润吸湿型高分子溶液，然后依次进行双向冷冻铸造和冷冻干燥处理，使得吸湿型高分子在三聚氰胺泡沫的孔隙中形成取向片层结构，得到大气集水材料。本发明通过将吸湿性高分子聚乙二醇和壳聚糖与三聚氰胺泡沫相互作用制成取向片层结构，不仅可以防止聚乙二醇高分子吸水后发生泄漏，而且使得制得的大气集水材料能够在施加的应变下相互接触并产生新的导热路径，实现热传输效率的调节，进而获得可快速释水的能力。
