Quaternary bionic fog water collecting material and preparation technology thereof
The invention discloses a quaternary bionic fog water collecting material. The material is prepared through a chemical etching technology and an electrostatic spinning method. Firstly, an ammonia alkali solution is prepared, a copper net is soaked in the ammonia alkali solution, so that Cu (OH) 2 microneedles are generated on the surface of the copper net, the copper net with the Cu (OH) 2 microneedles serves as a receiving substrate, a layer of beaded hydrophobic electrostatic spinning film is electrospun on the surface of the copper net, and the Cu (OH) 2 microneedles and beaded nanofibers are crossed and interpenetrated to form the quaternary bionic Janus material with an asymmetric microstructure and anisotropic wettability. The material has the advantages of multi-element bionic property, hydrophilic and hydrophobic compounding of the micro-nano structure, high specific surface area and simple and convenient preparation process, has a one-way water guide function, reduces secondary evaporation of water, can realize efficient water collection and retention, provides a new thought for relieving fresh water resource crisis, and has a wide application prospect.
本发明公开了一种四元仿生雾水收集材料，该材料通过化学刻蚀技术和静电纺丝方法制备。首先，配制氨碱溶液，将铜网浸于氨碱溶液中使其表面生成Cu(OH)2微针，以具有Cu(OH)2微针的铜网为接收基底，在其表面电纺一层串珠状疏水性静电纺丝膜，Cu(OH)2微针和串珠状纳米纤维交叉互穿形成了兼具不对称微观结构和各向异性润湿性的四元仿生Janus材料。该材料多元仿生，微纳结构亲疏复合，比表面积高，制备工艺简便，且具有单向导水的功能，降低了水分的二次蒸发，同时可实现高效的集水和保水，为缓解淡水资源危机提供了新的思路，具有广泛的应用前景。
