Here, 304 SS Received in revised form 28 June 2015 (stainless steel) was used as substrates and a micro-nano hierarchical structure was obtained by chemical Accepted 4 August 2015 etching with a mixed solution containing ferric chloride. The results showed that the water contact Available online 6 August 2015 angle (WAC) decreased obviously due to surface morphology changing after chemical etching process. However, we obtained a superhydrophobic surface with a WAC of 158.3 ± 2.8◦ after modification by DTS Keywords: (CH3 (CH ) Si(OCH ) ). Furthermo
