The electrochemical deposition of Cu(CH3(CH2)12COO)2 was presented to make the stainless steel surface superhydrophobic. The substrate was polished by abrasive paper firstly to make the micro-structures on the surface, then rough surface was covered with the Cu(CH3(CH2)12COO)2 by the method of electrochemical deposition. By our experiment, the deposition time affects the wettability of stainless steel surface distinctly. When the deposition time is 3 hours, the steel surface has the best hydrophobic property, and the value of contact angle of the steel plate surface is about 154.5°.
