Preparation of super-hydrophobic surface on stainless steel

To mimic the lotus leaf structure, binary microstructures at both micro- and nano-scale were constructed on the stainless steel surface by the eletroless plating. Super-hydrophobicity was achieved with a water contact angle of 150° and the sliding angle of 4° by modifying the textured surface by means of HFTHTMS ((heptadecafluoro-1,1,2,2-tetrahydrodecyl) trimethoxysilane).
