超疏水棉织物制备及其雾收集性能OACSTPCD

In order to solve the problem of water shortage,cobalt nitrate hexahydrate,urea and ammonium fluoride were used as raw materials to grow cobalt carbonate hydroxide nanorods on cotton fabric by hydrothermal method,and the superhydrophobic cotton fabrics were prepared af-ter surface treatment with stearic acid.The cotton fabrics are characterized by XRD,FTIR and SEM,and the effects of cotton fabric types,collection distance and fog flow on its fog collection a-bility were studied.The fog collection durability and self-cleaning performance of superhydropho-bic cotton fabric were also investigated.The experimental results show that the superhydrophobic cotton fabric has the best fog collection ability,which can reach 1 006.85 mg/(cm2·h).Fog col-lection capacities increase with the decrease of collection distance and the increase of fog flow.When the collection distance and fog flow are 3 cm and 237 mg/h,respectively,the fog collection capacity is as high as 1 514.65 mg/(cm2·h).In addition,the superhydrophobic cotton fabrics al-so have good fog collection durability and self-cleaning performance.
