Structural Fabrication and Characterization of Janus-fabric Sail With Directional Water Conveyance
摘要
Abstract
In order to solve the problem of insufficient freshwater supply in some regions,and inspired by nat-ural water harvesting organisms,this paper studies a Janus water harvesting sail with directional water trans-portation function,and characterizes its structure and performance.A mist collection device is used to conduct mist collection and related performance stability tests on the prepared Janus fabric.The effects of the treatment time of fluorocarbon copolymer with hydrophobic function,potassium permanganate oxidation time,hydro-philic finishing solution mass concentration,and SiO2 mass fraction on the water collection effect in the Janus fabric are explored.The results show that the Janus fabric prepared by the floating method performs well in abrasions and water washing resistance tests,and has unidirectional moisture conductivity.It can accelerate the transfer of collected droplets from the hydrophobic side to the hydrophilic side of the fabric,thereby keeping the hydrophobic side exposed to the fog source fresh and dry,and collecting more droplets.When the treat-ment time of fluorocarbon copolymer is 20 minutes,the oxidation time of potassium permanganate is 2 hours,the mass concentration of polyether modified silicone oil(hydrophilicity)is 80 g/L,and the mass fraction of SiO2 in the hydrophilicity finishing solution is 0.8%,the Janus fabric has the maximum water collection within 2 hours,which is 1240 g/m2.关键词
