| 1 | Superhydrophobic coatings for aluminium surfaces synthesized by chemical etching process显示文摘In this paper,the superhydrophobic coatings on aluminium sur-faces were prepared by two-step(chemical etching followed by coating)and one-step(chemical etching and coating in a single step)processes using potassium hydroxide and lauric acid.Besides,surface immersion time in solutions was varied in both processes.Wettability and surface morphologies of treated alumi-nium surfaces were characterized using contact angle measure-ment technique and scanning electron microscopy,respectively.Microstructures are formed on the treated aluminium surfaces which lead to increase in contact angle of the surface(>150°).Also on increasing immersion time,contact angle further increases due to increase in size and depth of microstructures.Additionally,these superhydrophobic coatings show excellent self-cleaning and corrosion-resistant behavior.Water jet impact,floatation on water surface,and low temperature condensation tests assert the excel-lent water-repellent nature of coatings.Further,coatings are to be found mechanically,thermally,and ultraviolet stable.Along with,these coatings are found to be excellent regeneration ability as verified experimentally.Although aforesaid both processes gener-ate durable and regenerable superhydrophobic aluminium sur-faces with excellent self-cleaning,corrosion-resistant,and water-repellent characteristics,but one-step process is proved more efficient and less time consuming than two-step process and promises to produce superhydrophobic coatings for industrial applications. | Priya Varshney Soumya Sanjeeb Mohapatra Aditya Kumar | 2016 | International Journal of Smart and Nano Materials2016，7，4： | 0 |
