Heat-conducting water vapor adsorbent as well as preparation method and application thereof
The invention provides a heat-conducting water vapor adsorbent as well as a preparation method and application thereof, and relates to the technical field of adsorption water taking. According to the heat-conducting water vapor adsorbent prepared by the invention, a quasi-core-shell structure is formed by the organic silicon microgel, the polydopamine and the metal coating, the organic silicon microgel is coated with the metal coating, and the organic silicon microgel and the metal coating are bonded through the polydopamine; nano-silver catalytic point locations are uniformly distributed on the surface of the polydopamine, and the metal coating is in contact with the nano-silver catalytic point locations. The prepared adsorbent contains a large number of hydrophilic organic groups, and the number of the hydrophilic groups is adjustable, so that the adsorbent can catch water in a wide humidity range. The adsorbent particles are stacked to form an adsorption bed with a three-dimensional heat conduction channel, so that the heat and mass transfer capability can be effectively enhanced, and the water release and water production efficiency is greatly improved. In addition, the prepared adsorbent is stable in property and reusable, the water production cost can be effectively reduced, and the production benefit is improved.
本发明提供了一种导热式水蒸气吸附剂及其制备方法和应用，涉及吸附取水技术领域。本发明制备的导热式水蒸气吸附剂，由有机硅微凝胶、聚多巴胺和金属镀层形成准核‑壳结构，其中，有机硅微凝胶由金属镀层包覆，二者之间通过聚多巴胺粘结；所述聚多巴胺表面还均匀分布有纳米银催化点位，金属镀层与纳米银催化点位相接触。制备得到的吸附剂中含有大量亲水有机基团，亲水基团数量可调，从而使其能够在广湿度范围内捕水。吸附剂颗粒堆积后形成具有三维导热通道的吸附床，可以有效加强传热传质能力，大幅提升释水和产水效率。另外，制备得到的吸附剂性质稳定，可重复利用，可以有效降低产水成本，提高生产效益。
