Synthesis And Characterization Of Metal Super-Hydrophobic Surfaces

Abstract

In this our dissertation work we prepared superhydrophobic surface on zinc, Aluminum and copper metals surfaces and on fabric surface. On metals surface we created superhydrophobic coating by etching and hydrothermal coting process. In this process we use KOH and NaOH use as etching solutions which creates microstructure on metal surfaces. Our coating material was stearic acid and lauric acid. After coating contact angles of surface with water droplets was measured with the help of image J capture software. Higher contact angle was 159.57° on aluminum surface by etching process, which shows superhydrophobic characteristics. Our Another work on fabric surface. In coating on fabric surface our coating method is novel and not reported yet. In this process contact angle is 153.56° degree, which shows superhydrophobic characteristics.
