Underwater siphon material and preparation method and application thereof

Abstract

The invention relates to an underwater siphon material and a preparation method and application thereof; the contact angle of the siphon material with air bubbles under water is 0 DEG, and the siphonmaterial is superhydrophobic woolen yarn capable of stably transporting underwater bubbles, which is made by soaking a woolen yarn in a modifying agent FAS-SiO2 / PADMS with low surface energy, carryingout hydrophobic modification treatment on the woolen yarn, and then drying. The preparation process is simple and easy to perform, the reagent is cheap, easy to obtain and environmentally friendly, the underwater siphon device is assembled according to the characteristic that the superhydrophobic woolen yarn is superhydrophobic and super-aerophilic underwater to arrive at underwater gas transportation, experiments prove that the transportation mode can be kept stable for a long time, when a certain part is damaged or broken, transportation can be recovered just by knotting two ends of the woolen yarn, and the advantages are obvious. The underwater siphon material has wide application prospects in the development and application of new technical fields such as directional transportation ofunderwater bubbles, and underwater gas separation and collection.

Description

technical field [0001] The invention belongs to the technical field of superhydrophobic materials, in particular to an underwater siphon material and its preparation method and application. Background technique [0002] Generally speaking, the realization of superhydrophobicity at the material interface depends on two points: one is the construction of rough structure, and the other is the modification of low surface energy substances. So far, there are many methods for preparing superhydrophobic surfaces, such as etching, electrospinning, vapor deposition, etc., but most of the preparation methods have disadvantages such as complicated preparation process, cumbersome process, expensive price and unfriendly environment. . [0003] In addition, due to the excellent non-wetting properties of superhydrophobic materials, it has broad application prospects in many fields such as oil-water separation, self-cleaning, and metal protection. However, most of these applications are b...

Problems solved by technology

[0004] Up to now, pipelines are generally used to realize underwater gas transportation. Although the transportation efficiency is relatively high, it generally needs to provide a large amount of power, and the pipeline itself cannot capture the gas in the water, and can only realize the gas at both ends of the nozzle. transportation

In addition, if a certain part is damaged or broken, on the one hand, it is difficult to repair, on the other hand, the cost is high, and the transportation has obvious defects
