Abstract

A pyramid/nanowire binary structure is fabricated on the silicon surface via a NaOH anisotropic etching technique followed by a silver-catalyzed chemical etching process. The silicon surface shows a stable superhydrophobicity with high contact angle of 162° and small sliding angle less than 2° after being modified with octadecyltrichlorosilane (ODTS). The binary roughness of pyramid/nanowire structure presents a stable composite interface of silicon-air-water and responsible for the superhydrophobicity of silicon surface.
