Preparation method and application of atmospheric water adsorption polymeric material and atmospheric water collection method
The invention discloses a preparation method and application of an atmospheric water adsorption polymeric material and an atmospheric water collection method, and belongs to the technical field of atmospheric water collection. The preparation method of the atmospheric water adsorption polymeric material comprises the following steps: dissolving an adsorbent in water, and stirring to form a solution A; placing the solution A in a freeze-drying machine for freeze-drying treatment to form a film B; mixing calcium chloride, lithium chloride and water according to a certain mass ratio to form a solution C, immersing the film B into the solution C, and standing and reacting for a period of time to form a precursor D; the precursor D is placed in a freeze dryer for freeze drying, and the adsorption polymerization material is obtained. According to the adsorption polymeric material prepared by the two-step freeze drying method disclosed by the invention, the moisture absorption capacity under low humidity can reach about 1.6 g/g, and the moisture absorption performance of the material is greatly improved.
本发明公开了一种大气水吸附聚合材料的制备方法和应用以及大气集水方法，属于大气集水技术领域。该大气水吸附聚合材料的制备方法包括将吸附剂溶于水中搅拌形成溶液A；将该溶液A置于冷冻干燥机中进行冷冻干燥处理形成薄膜B；将氯化钙、氯化锂、水按照一定的质量配比形成溶液C，将薄膜B浸入溶液C中静置反应一段时间形成前驱体D；将前驱体D置于冷冻干燥机中进行冷冻干燥得到吸附聚合材料。通过本发明的两步冷冻干燥法制备的吸附聚合材料，使得在低湿度下湿度吸水量能达到约1.6g/g，较高地提高了材料的吸湿性能。
