Embodiment 1

[0029] 1. Preparation of copper surface with nano-block structure by electrodeposition method: first, select a copper needle with a length of 3 cm. In order to remove the pollutants on the surface of the copper needle, ultrasonically clean it with ethanol and deionized water for 5 minutes, and then use 0.1M hydrochloric acid solution to remove the oxide layer. The treated copper needles were electrodeposited by an electrochemical workstation, wherein the copper needles were used as the cathode, the platinum electrode was used as the anode, and the saturated calomel electrode was used as the auxiliary electrode, and the selected electrolyte was 0.5M copper sulfate solution. Deposition was performed for 600 s under the time-current window. The copper needle was taken out, washed with ethanol and dried under nitrogen flow for 3 min.

Abstract

The invention provides a method for collecting water mist with a silica gel block material having a hydrophilic and sliding surface and a tapered copper needle with a superhydrophobic-hydrophilic surface. The present invention includes preparation of copper surface with nano block structure by electrodeposition method, preparation of copper hydroxide nanowire at the tip of copper needle after electrodeposition, preparation of tapered copper needle with superhydrophobic-hydrophilic integrated surface, hydrophilic, Preparation of silica gel bulk material with sliding surface, silica gel bulk material with hydrophilic and slip surface as the substrate and a water mist collection combination assembled with tapered copper needles with superhydrophobic-superhydrophilic integrated surface. The collection rate when one copper needle is assembled on each substrate is about 9.05g / h, and the collection rate when the number of copper needles is six is ​​about 14.19g / h. Therefore, based on the stable and efficient water mist collection ability and the long-term stable wettability of the material surface, this kind of tapered copper needles with hydrophilic and slippery bulk materials as substrates and superhydrophobic-superhydrophilic integrated surfaces are assembled together. The combination of water mist collection can be promoted on a large scale.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to a method for preparing a silica gel block material with a hydrophilic and sliding surface and a tapered copper needle with a superhydrophobic-hydrophilic integrated surface for water mist collection. Background technique [0002] Materials with water-harvesting properties have received increasing attention in recent years. According to reports, water shortage is one of the pressing problems facing the future of mankind. How to quickly and efficiently collect moisture from humid air becomes a challenge. As we all know, fog generally exists in the humid atmosphere in desert or coastal countries. Organisms in nature have evolved surface microstructures that are conducive to water collection, which has inspired scientists for bionic research. Cacti reveal a unique integrated water-harvesting system incorporating cone-spines to accelerate transport of tiny droplets. ...
