Abstract
One‐stage preparation of superhydrophobic stainless steel surface is achieved by combining chemical etching and assembly. The contact angle of the prepared surface reaches as high as 175°. The correlative mechanism between the contact angle and surface morphology is elucidated from the dynamics perspective by controlling reaction conditions. The optimum reaction conditions are then determined. Experimental results demonstrate that the stainless steel surface achieves optimal water contact angle upon the formation of the “honeycomb” 3D network structure. Electrochemical corrosion test shows that the prepared superhydrophobic stainless steel surface possesses 16 times higher corrosion resistance than common stainless steel surface.
