Photo-thermal response atmospheric water collection material as well as preparation method and application thereof
The invention discloses a photo-thermal response atmospheric water collection material as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials. The photo-thermal response atmospheric water collection material comprises a hydrogel base material, bionic photo-thermal dip-coating liquid and a salt-based moisture absorbent, the surface of the hydrogel base material is coated with the bionic photo-thermal dip-coating liquid, the salt-based moisture absorbent is loaded in the hydrogel base material, and the bionic photo-thermal dip-coating liquid is composed of tannic acid, trihydroxymethyl aminomethane hydrochloride, aminopropyltriethoxysilane, Fe < 3 + > and ethyl alcohol. The photo-thermal response atmospheric water collection material provided by the invention has relatively good moisture absorption performance and moisture release and adsorption performance, and solves the problems that moisture adsorbed by a common atmospheric water collection material is difficult to release and an existing photo-thermal conversion coating is relatively high in price; a material which is low in price and convenient to use is provided for agricultural water collection and agricultural irrigation.
本发明公开了一种光热响应大气集水材料及其制备方法与应用，属于高分子材料技术领域。该光热响应大气集水材料包括水凝胶基材、仿生光热浸涂液和盐基吸湿剂，水凝胶基材表面涂覆仿生光热浸涂液，内部负载盐基吸湿剂，所述仿生光热浸涂液由单宁酸、三羟甲基氨基甲烷盐酸盐、氨基丙基三乙氧基甲硅烷、Fe3+和乙醇组成。本发明提供的光热响应大气集水材料具有较好的吸湿性能和释放吸附水分的性能，解决了常用大气集水材料吸附的水分释放困难以及现有光热转换涂层价格较高的问题，为农业用水的收集以及农业灌溉提供一种价格低廉、使用方便的材料。
