چكيده فارسي :
An innovative, simple and cost effective way has been suggested to the fabrication of a micro-nano structured superhydrophobic on aluminum alloy 2024 just by immersion steps. The water contact angle on the superhydrophobic surface was measured to be 167.1°. Micro-nano roughness was observed by scanning electron microscopy on the surface. The surface chemical composition was performed by EDS analysis and the presence of carbon-containing compounds was determined. The etching time effect on the contact angle was also measured and the best time was measured for 4 minutes. It is estimated that 97% of the surface of the superhydrophobic surface that is in contact with the drop of water is formed from the air. Self-cleaning properties of the superhydrophobic surface were studied. It was also observed that the surface is able to remove various liquids.
