Superhydrophobic surfaces are conventionally prepared employing two steps: roughening a surface and lowering their surface energy. It is known that the cleaned coppers substrates when immersed in an ethanolic stearate ,solution, transforms anodic electrode into the superhydrophobic surface due to reaction between ,copper, and stearic ,acid,.
